What do you do with Bad Gasoline

topic posted Mon, June 15, 2009 - 2:25 PM by  Dano
Seems an easy question...
I'm sure with a bit more time on the phone may track it down, but so far I am coming up with blanks...

What do you do to properly dispose of Bad (water/dirt contaminated) gasoline? The places that take oil, don't take gas. The stuff is questionable enough that I wouldn't "dry it" (chemically treat it) for use in any engine I own. I dislike having more gas around in my garage than I need.

Oh I'm in N. California... and talking about a just a few gallons.

  • I finally found that there is One site (the primary County disposal site) that will take it but you have to leave the container behind... with the possibility of picking it up later (yeah right). Kinda understandable but also kinda lame, being that they will surely slap you if you bring it in a non-approved container.
  • Non-engine uses of gasoline---

    - lantern fuel
    - camp stove fuel
    - pre-wash stain remover rubbed in with rag
    - fire staff & poi fuel
    - removing road tar & asphalt stains from cars
    - soaking dirt and grease from bike & machine parts
    - pesticide spray, in water solution
    - herbicide spray, in water solution
    - barbecue charcoal accelerant
    - cleaning grease, grime off bare metal surfaces
    - pre-soaking potholes in asphalt driveway to get patch compound to stick better
    - & more....
    • Using gasoline as a fuel for a lantern or a stove gives me some pause.

      • Unsu...
        For nearly a century - -Coleman lanterns have been designed to be used with gasoline.

        • So Briggi, about gasoline as a much do you suggest it should be watered down? How does it compare (in efficacy) to other chemicals such as bleach or brine? I ask because where I live they've decided to ban the use of Roundup and the like for "cosmetic use" (that means around your yard etc.), and I expect to soon have a "weed problem" I need to fix.

          Way back when I used to live in poison ivy country I used gasoline and/or used crankcase oil to knock down those weeds, but back then gas was really cheap so using it full strength wasn't a big deal. But with gas headed back to three bucks a gallon I'm looking for cheap, easy, effective, persistant weed killing in number of places.
          • How much do you have? MY recommendation would *totally* depend on how much gasoline we're talking about. . . .and. . . uh. . . how did you gasoline go bad in the first place?

            • Gas goes bad real easy. Leave some in a can for a year and it smells like varnish and it's sure damn gum up a fuel line if left there for a few seasons. There's a gas stabilizer you can add to it so it stays ok.

              I would not use it for most of the suggestions here.

              To the best of my knowledge, it works in campstoves and lanterns that were specially designed for it. I think we should be clear about this. There are a lot of applications in stoves and lanterns that will go boom. Seems to me it needs to be fed under pressure so's the flame doesn't backtrack to the fuel reservoir. Am i wrong about this?
              • pressure yes, campstoves/ lanterns have a little pump, it will be fine

                one thing i tried you should probably not-

                really bad gas in my lawnmower years ago, poured it out on dirt- we're talking about a quart.

                figured ok, light it up get rid of it.

                WOW what a mistake HUGE fire for way longer than i was ready for, pretty frightening good thing it was on dirt. burned for like half an hour

                the white gas factory recommended actually has a higher flashpoint volatility than unleaded extra.
                Life is a calculated risk.
                Colemans has gone to selling more LED lamps now than fossil-fueled. A sign of the times? Probably an overdose of 9/11, putting too much fear in American hearts & minds.

            suggested app is trial/error. greater concentrations could be total defoliant.
            other weed subduers> planting marigolds, tobacco leaf, garlic, salt, hand-pickin
            the fun is in getting to experiment. look at it as a home science project.
    • - pesticide spray, in water solution
      - herbicide spray, in water solution
      - pre-wash stain remover rubbed in with rag<<<<<<<<<<

      all of these put the toxic wast into the water supply, a Major NO NO. And ridicules suggestions. But then out'a sight, out'a mind .
      Water and gas don't mix, gas just floats on top of the water, how would you suggest the two be mixed into a " water solution" any way ?
      Gas will not work as a charcoal lighter, it burns off long before the charcoal gets hot enough to ignite. And throwing a match on gas soaked anything, will give you a sudden flash of fire, and removal of unwanted, and wanted body hair !
      The gas in question, being contaminated with water can't be used as lantern of stove fuel. the water stays on the bottom, where the pick up tube draws the fuel from. Would you just " burn off" the water until you get to the gas ;-) Neither item would even light with this mix in them.]
      All in all, pretty ill conceived suggestions for such a dangerous, and toxic material.
      • Dan>
        The thing that puts toxic into the water supply is when you pour gasoline into the water suply. Otherwise gasoline will evaporate, or have its constituent hydrocarbons broken down upon interaction with soil-based microbes, long before reaching the water table.

        Getting water and gasoline to mix? Employ a surfactant like Tide. Apparently he can't get water and gas to NOT mix is why he's asking to begin with.
        WWII fighterplane engines had a water injection system to slow carburation ignition and actually get a greater RPM HP output for that extra burst of power..

        The charcoal absorbs gasoline enough to act as a wick for it to catch on. Or use some gas soaked newspaper balls and twigs to hold flame in getting the BBQ blaze happening .

        Fire can be dangerous. If you are stupid enough to slowly hang in after lighting up some volatile material, then you deserve what you get. Every kid knows to leap back when lighting up fireworks.

        If you can't stand the heat then get out of the kitchen. If you feel insecure about some twitty little perceived danger then move to Russia where Big Brother takes care of you.

        Remember you're trying to get rid of the stuff in a useful practical manner because it's a pain in the ass having to haul it to approved government facilities.
        • I think there is some middle ground between being idiot over coddled children of a nanny state ( i don't think russia qualifies anymore, Scandinavia maybe) and being a reckless endangerment to cellf and others. I googled around a little, and it looks to me like gasoline does get into the water table at least under some conditions. I reckon it would depend on how much gas, how deep the water table and the soil type. Gas goes boom!!!!! It is also quite toxic. No need to be fearful if we are respectful and mindful. I know i've done some pretty stupid things with it and am lucky to be here to tell about it.

          If i have a few gallons go bad, i use it to start brush fires or such. I have also just let it offgas itself gone. If i have a little water in gas, i just add some regular isopropyl rubbing alcohol.
          • Wil >

            "Russia" is a metaphor for America. Fasten your safety belt.

            Rusting holding tanks under an abandoned service station ? ---maybe.
            3 gallons splashed directly on a beach 20 feet from a lake? --- never make it there.

            Toxic? 3/4 of the cosmetics in your home --- and most of the food you eat is toxic.

            Yes, respect something that may harm you. Fire has been a powerful yet respected friend to humankind all throughout history. Why outlaw fire now. Use fire with respect but don't insist that it wear a hazard label. ( I resent the ninnyfication of America).

            Cars are both toxic and quite dangerous. Shall we outlaw them?
          • Unsu...
            you just wait. We are sliding into a nanny state like the world has never seen.
            And the weird thing is the people seem to be clamoring for it.

            Tell me what to do. Regulate this, prohibit that, force me to make choices you pre-select.
            It's horrible to watch stupid people en masse who lack a sense of unintended consequences.
            • In loco parentis.

              We are so goddam stupid that the business of government & education has become to foster draconian regulation to keep us from harming our dumb selves.
              • I am all for you harming yourself Briggi. As Dan stated that right ends when you start harming me... And yes FYI pour gas 20 yards from a lake will put it in the system. The old head in the sand thing. You don't see it but one of the biggest problems with water is not our lack of it but rather the fact that we have grossly polluted a shitload of it.

                The fact that you consider it no big deal to dump hazardous waste and actually recommend it demonstrates, for the defense of others, even more regulation and higher fines are needed. I would like to see personal fines for illegal dumping of hazardous materials in the 25,000 to 50,000 dollar range plus cleanup costs. It is pretty amazing how little asbestos makes it's way to landfill now that Washington is fining 10,000 for illegal dumping of hazardous waste.

                Motor oil makes it to the waterways. So does gasoline. They are toxic and contaminate many thousands of gallons of water per oz. This is even more disturbing since you live in Utah you are in the drainage basin for the Colorado. Currently one of the most polluted and essential water sources for the entire SW.

                Now we are done with this topic
                • J-sinn >

                  Don't hurt yourself ----it's not worth it.

                  With regard to your ecological sensibilities, let us revise that figure to 150 feet from open water --- same as USFS parameters.
                  Feel better now?
                  • This is the maximum depth. Additional responses will not be threaded.
                    The movement of the gasoline towards the water table is going to be greatly affected by how much or whether it rains and soil type. Factors we can't factor. It feels just plain out and out wrong to pour it on the ground.
                    • Natural systems have the ability to absorb SMALL quantities of industrial substances. And will break down some hydrocarbons through soil chemistry and bacteria. Developing new strains of microbes for remediation of industrial polution is a fast growing sector of genetic engineering. They are working on a bug to break down radioactivity as well. They sell clutures to remediate oil spills. That's big business for you.

                      Another interesting area of research is Ayurvedic Medicine, where the hair of the dog that bit you is prescribed --- much like homeopathy. Application of SMALL quantities of unnatural substances/poisons to nature will jumpstart that natural system working to find and develop an antidote.

                      Be mindful here that I am proposing various theories for open discussion. I am not "reccomending" anything. So If folks have any problem with this, then just simply default to the " playing it safe" mode.

                      Personally I've never poured out nor discarded old gasoline. I've always found some use for it. My Mom taught us boys to not be wasteful.

                    briggi you need to get out more and read newspapers and watch 60 minutes and 20/20 and such if im recalling it right 60 minutes a few yrs back had an episode where they tested the water in a resovoir lake for washing dc that water that people drink had all types off stuff in it from birth control medicines anti depressants chemicals of all types and etc from people dumping stuff into the gutters on the streets or putting on the ground as you suggest for weed control to people flushing expired or medicine not taken any more down the toilet. you need to make sure that what you do does not harm the enviroment bottom line. I'm not saying be a tree hugger but be responsible.
                    • Mark you are sooooo right.
                      Now tell it to the farmers of America.
                      What pesticide, what herbicide, routinely utilized in conventional non-organic standard agrobiz farming, in MASSIVE quantities, does NOT have a substantial petrochemical component? And this is 95% of the shit you buy and eat from the supermarket. Are we supposed to think that our backyard garden practice is going to make a really huge difference?
                      Until American agriculture gets up to speed and gets held accountable, it may matter very little what the other 2% of The People with their private gardens do to add to that filth in your lake.
                      I'm really tired of the common man having to shoulder the burden for what corporate industrial and corporate agricultural interests routinely do as if it were the common man responsible.

                      Have 60 minutes do a show on this.

                      60 minutes did a show telling how 6 and 7 year olds were growing breasts and beginning menstruation due to anti-biotic growth hormones being injected into meat-cows to promote growth and then the families of these children purchased the tainted meat. ... are we consumers supposed to take the guilt trip rap for that too?

                      I can be a totally clean green example but WTF good does that do in a world that is totally full of shit filthy? Go reform industry. Go reform agriculture. And stop beating up people who are simply doing the same thing that mutlinational industries worldwide are doing.

                      And there you have proof of the old adage:

    • using gas to clean not a good idea bud gas is flamable and it would leave the residue behind and if your wearing the jeans or what ever you clean the stain off of it might light if near a flame -not a good idea my dads neighbor was telling me yrs ago about how he cleaned stuff with gas (clothing engine parts etc) and they did light even after being washed off
      • Great.
        Now tell that to the dry cleaning industry, and tell that to the makers of spot removal fluid --- both of which have refined petrochemicals as their major active ingredient. At worst, by using gasoline to get a stain out of your jeans, you are doing the same thing as the clothes cleaning industry is doing worldwide in citys around the globe.
        Why not prosecute the industries who daily literally pour petroleum residues into waterways and oceans instead of the guy who does the same dang thing in his home ? You want to raise awareness? Go do that.
      • Unsu...
        ************and they did light even after being washed off *************

        I rather suspect that the "washed" part of the story was not a reality in the actual incident but, merely something invented after the fact as the story was retold.
        Such a scenario is entirely out of the question if the washing is done with soap and water.

        Maybe they washed it with alcohol or kerosene or just gave it a good rubbing but definitely they did not use soap and water.

        The stench from Gasoline is powerful and can survive a washing - or two but, the stench is not capable of accelerating any flammability in the material.

        Dry cleaners use Tetrachloroethylene. It is supposed to "completely" evaporate from the material.
        I know of no research that shows this to be fact or false.

        All that being said:

        "Gasoline is a refined product of petroleum consisting of a mixture of hydrocarbons, additives, and
        blending agents. The composition of gasolines varies widely, depending on the crude oils used, the
        refinery processes available, the overall balance of product demand, and the product specifications.
        The typical composition of gasoline hydrocarbons (% volume) is as follows: 4-8% alkanes; 2-5%
        alkenes; 25-40% isoalkanes; 3-7% cycloalkanes; l-4% cycloalkenes; and 20-50% total aromatics
        (0.5-2.5% benzene) (IARC 1989). Additives and blending agents are added to the hydrocarbon
        mixture to improve the performance and stability of gasoline (IARC 1989; Lane 1980). These
        compounds include anti-knock agents, anti-oxidants, metal deactivators, lead scavengers, anti-rust
        agents, anti-icing agents, upper-cylinder lubricants, detergents, and dyes (IARC 1989; Lane 1980). At
        the end of the production process, finished gasoline typically contains more than 150 separate
        compounds although as many as 1,000 compounds have been identified in some blends (Domask
        1984; Mehlman 1990). Information regarding the chemical identity of gasoline is located in
        Table 3-l."

        I don't think I'd want anything exposed to all that crap to be in contact with my skin all day long after just one ( even two) washing. The chances that you'll get it all out in the wash are slim, slim to none actually.
        Flammability notwithstanding that's a lot of crap and if you can smell something after a washing then it's a sure bet that there's something still in the material. It may not burn but, it might be toxic.
        • Gawd. Even though i kinda like the sharp sweet stink of gasoline, tuning and repairing carburated bikes constantly in an otherwise tidy, ventilated shop still SUCKED cuz of the wreckage it wreaked to skin, hair, clothes, throats, nasal passages, sandwiches, foreskins, factory manuals, custom paintjobs, etc.
  • Damn... Only on the Internet... never thought a simple question would lead to so much fun and hijinx.

    Here is what I did with my 3 gallons of bad gas... I ordered a free Oil Pickup container from my recycler (as I DO have curbside oil pickup IF you call for it) . The container is a 2 Gallon "approved" container. I put most of my bad gas in there and will take it to the central toxics facility and leave it. (so I don't have to buy and leave a container or use a milk jug) .

    The rest (about 3/4 gallon) I am using to clean motorcycle parts (great for soaking off old gaskets... wire-brush cleaning old spokes and also just for degreasing engine parts... I use a big stainless steel mixing bowl for cleaning in and then let what gas is in the bowl degas (a 1/2 cup is evaporated in a day or so)

    Thanks for the all opinions ;)
  • I have read through all of the replies before making this response. Very entertaining, thank you!!! Although against popular belief, gasoline in its liquid form does NOT burn. If you do not believe me, then please consider this: If your car engine (not always fuel-injected) becomes "flooded" due to excessive peddle pumping, why will the engine not start? Reason is, it's flooded! It has nothing to do with the spark plugs being "wet." So, how is it that an engine runs on liquid gasoline? Answer: It does NOT. Have I raised a few eyebrows, yet?

    Gasoline was a nuisance by-product from refined oil back before the car engine was invented. It was simply thrown away into the dirt. If you think that was amazing. At around the same time, when copper ore was smelted for refining, a dark blue substance was its by-product and that was simply thrown away, too! It was later discovered that the blue substance was "Silver," something that has increased in value over the years, used in Minting U.S. Coins, and became an industry standard for consumption in many of our electronic products. (So, do we really get smarter with age?)

    Liquid Gasoline does not burn, especially out in the open air. It is the vapors, known as a "GAS," is what ignites. The vapors are so volatile, it burns rapidly enough to give the "impression" that the gasoline is on fire when, in fact, as vapors are being created from the liquid form - it burns from the surface of the liquid gasoline.

    Consider this: If liquid gasoline actually burns, it would not be safe enough to store on our vehicle gasoline tanks. And if you were actually wondering how a "Flooded" car engine is corrected; simply keep the gas peddle pressed to the floor (without pumping) and keep cranking the engine (at 20 second intervals - 30 seconds apart) until the cylinders start firing up. Back off the gas peddle a little to keep the RPMs from exceeding 3000 until all liquid gasoline is flushed past the exhaust valves and you have a stable engine idle.

    As for what "Bad Gasoline" really is... It's not considered bad when you have dirt & water mixed in. Water will always collect within a gas tank due to plain atmospheric condensation. It usually occurs more frequently in the mornings, when it's cooler. For instance: You purchase a cup of cold soda at the fast food restaurant and go outside. A few minutes later, you have managed to collect moisture all around the outside of your cup - the drink is NOT leaking, it just collected water out of plain air that's all around you. Our gasoline tanks go through the same process and collect water in the same fashion. The easiest way to reduce this water collection, is to keep your gas tank full as much as possible - do not run the fuel down to near empty. When you do let the tank get to near empty before fill-ups, you create more surface area for the water to condense on (within the tank).

    Contrary to popular belief, too, is that water also evaporates. Try this at home: Use a clear jar and fill it with water before closing the jar's lid. Place that small jar of "sealed-in" water on a shelf. To speed things up, the shelf should be a window shelf that has the Sun shining on it in the morning. Check it in about a month to see if that "sealed-in" water is still ALL there.

    The point here, is that water in gasoline also evaporates, too. As for dirt: That dirt & rust is caught in the fuel tank mesh filter which is most likely replaced after 20 years of service. The mesh filter is so good that it also expands to keep water from going through, too. Sometimes, it's so good, that it will also keep the gasoline from passing through it when it's saturated with water! (See below, for options.)

    Bad Gasoline is actually a fuel that has decomposed, the properties have separated making it unable to vaporize properly to burn in an engine cylinder when compressed. Bad Gasoline occurs ONLY over time. If you only have a water/dirt contamination issue, then do NOT bother with disposal. You will just waste your time & money. Others have suggested on this thread, to simply mix with fresh fuel and that IS the correct solution. It is a natural process & it occurs in nearly every automobile.

    However, if the Bad Gasoline is actually bad from sitting over many years, then the liquid fuel has changed its properties. It will smell like varnish and work like varnish. It is still volatile and will work to clean oily items such as tools and other engine parts, so it should be stored in a sealed metal container IF you plan to use as such. Otherwise, do not bother with trying to empty your gas tank of suspected Bad Gasoline. If you are certain your existing fuel is bad, have your vehicle towed to a garage who handles vehicle gas tanks. Pay them for their expertise in removing your gas tank to wash it out clean. They have the professional ability to put it back together so that there will NOT be leaks and you can go about your business at the gas pump like the rest of the people who can concentrate on the more important things in life - such as life itself!
    • Gregg, Being new to this tribe here are a few things I'd like to point out.
      #1 We're not a bunch of 5th graders, so your run on about liquid gas , condensation etc. is more of an insult than anything.
      #2 Your assertion that water will evaporate from a sealed container is.......well, stupid.
      #3 Copper and silver have been mined, and separated in SW NM. for over 400 years, starting with the Pueblo tribes. ( Silver City NM. }
      #4 Advising that someone with car problems, should take it to a, " professional " at a garage. ......That just makes our skin crawl. This is DIY, Do It Yourself !

      "So, how is it that an engine runs on liquid gasoline? Answer: It does NOT. Have I raised a few eyebrows, yet?"

      Answer: Yes, you have raised a few eyebrows, and they all seem to be asking, " who is this Twit ? "
      Your approach would be better served on Wikipedia, I understand a lot of kids go there for homework info.

      PS. And I'm not even the most cantankerous of the lot, close though.

        Amen to that. PLUS the worst thing in the world is to have some god dammed "professional" mucking about with your car. Why on earth would you let a school teacher, Doctor, Lawyer, or priest ?? I mean Come on man use your head.

        Now taking it to a Skilled Tradesman might be the right idea but never - - EVER - - take your car to a professional.

        Trades persons are NOT professionals. I'd never insult a tradesman with such a pejorative.

        Professionals are people who have given their lives over to some "higher calling " or so they think it is.
        The term has nothing to do with earning money or doing a thing well or having any education or how you dress. None of that has anything to do with professional. That's all stupid made up crap that people cling to because ( for reasons that baffle me) they are insecure about what they do so they feel some need to pretty it up using a world they absolutely do not understand. In the end they only look ignorant.

        Every time a Trades man or an Avocational Expert like an Engineer takes up the instruments or tools of his vocation he brings order to an other wise chaotic universe. There is no profession that can make such a claim.

        • ? I don't think white collar guys are the only professionals......what about the world's oldest professionals. I use it just to mean someone who is dedicated to doing what they are doing and not an amateur.
          • Unsu...
            I think the bastardization of the world "professional" started in the 1960s

            America's has squads and squads of kids who were the first in a whole family's history to have a college degree.
            irst whole generation. When sonny with the diploma came home he was treated like a Greek god, wore clean shirts and didn't get his hands dirty and earned more money in a month than his dad in a whole year.

            Suddenly it became popular to identify with what it was you did for a living instead of who you were as a person.

            It was all down hill from there.
            Every one who actually did a thing wanted to be an "engineer" of some species or other. Secretaries were suddenly Administrative Assistants and Howard Cosell converted every moron who could move a ball from point A to point B as a PROOOOOOOFESSIONAL.

            Then after a while the affectation "engineer" lost it's flair when every Janitor was calling themselves engineers. and other pseudo feel good affectations weren't working so well because every body knew that the person adopting them was not really educated in the field the pseudo title suggested . Suddenly every one was casting about for a word that ( to their uneducated minds ) didn't have any fixed meaning but, still a word that sounded important.. Eventually people started using the word professional and then it too took on a life of it's own being bastardized to stand in for "business attire, "business decorum." earning an income from a vocation, the level of education one had, and yah that level of expertise that differentiates a rank amateur from an expert which used to be said plainly and well using the world "expert" but, god damn if the word "professional" was not bastardized into service for that too.

            Now thanks to scads of people who don't speak their own language, the term is all but meaningless.

            Pretty soon Snoop Dog's "Faschizzle madrizzle" will lose it's meaning too.

  • I noticed I have a 5 gallon can of gasoline has been knocked over by my dog onto loose dirt under my cottage. I covered it with unpolluted dirt. Is this enough to "let the microbes do their business?" If it is not completely covered how long is the dirt a fire hazard for? I am not near a water table and I think about 3 gallons spilled. Would watering down the dirt be helpful to make it absorb quicker?
    • How to make bad gasoline "badder" -- mix it with dirt. Since the volatile vapors of gasoline are what makes it so much fun to play with in combination with matches, I'm guessing from a fire hazard perspective, even a day or two in the company of a whole bunch of dirt is going to really put a damper on the flamability side of things.

      I vaguely recall experimental validation in this regard (though not in s strictly scientific sense) involving ant hills and a couple of ten year old boys (at least one of which prefering to remain anonomous-cough-).

    Take the gas camping with you and have some fun around the campfire. Once the fire is going throw the gas into the fire one cup at a time. FuWOOOOF! crackle pop crackle FuWOOOOF! Great fire balls of fun!


    Poor about a cup of gas in a large flat pan and place it in the sun to evaporate everyday until it is all gone.

    BE SURE to place the pan on a non-burnable surface away from anything that can catch fire.

      Some how I rather suspect that the Greeners will object to those.

        "Some how I rather suspect that the Greeners will object to those. "

        Not everyone is a Greenie though and that being said, the recommendations could have included dumping the gas in a sewer drain or a public water source or for use for huffing or immolation so all things said it could have been worse. Besides how many of those Greenies are attend Burning Man the world renowned waste of environmental pollution through the use of fossil fuels in everything from travel to cooking to art?

        The point is still well taken however...I propose this: use the stuff to light fires as a firestarter or filter the gas throught a couple of filters including a water remover filter or after filtering the solution down to crap gas and some water you add some Heet or some such water remover gas treatment and then mix the solution 10 gal good gas to 1/2 gallon of the crap and burn it anyway cause the stuff is as good as gas mileage if nothing else.

          I ain't no greener but I am pretty much opposed to pollution of any sort.

          Of course the definition of what a pollutant is, constitutes a sticking point the warmers have with me ( or I with them).
          But as a general proposition I think that irresponsible or deliberate or willful mis-handling of things like VOCs, petroleum products, highly reactive polymers (like PCBs etc.) atomic waste, etc., etc., is wrong.

    I've read most of the posts but not all for sure so if I repeat anything, excuse me...

    I've removed gas out of boats that has turned to laquer (the octane has evaporated) and if run through the engine it will always gum up everything and expect a carburator rebuild...

    Resaleing the old laquered gas is what we do! Anyone say that yet?

    If we have any big wood piles to burn with alot 'green' wood in the mix then we save 5 gallons or so for ourselves so for the starting of the dozed wood piles...

    Other people will pay for this same gas at half the price of regular gas prices these days for burning and other purposes... So I suggest what we do, sell it! Gas sells pretty easily even if it is old...
    • Mixed with old crankcase oil, "bad gasoline" becomes an effective and inexpensive treatment for wood roofing shingles, or unpainted "natural" wood siding. The oil saturating the wood is what adds longevity in protecting exposed wood surfaces. Dispersed through a pump up "garden sprayer" this is a fast and easy way to protect exterior natural wood surfaces. Spraying roof shingles or shakes with this mixture (used oil, mixed with old gas or diesel fuel), was a common method of treatment to keep shakes and shingles waterproof and from cracking, though today this should only be considered for outbuildings and or where building and fire codes would not be infringed.

      Another excellent use is to again use the gasoline with old oil and spray it on form boards as a concrete release agent. Another use related to concrete construction is to pour the gasoline on Styrofoam form "block outs" to dissolve the foam after the concrete is poured.

      Still another use for gasoline, though this is an extreme instance of a desperate use, is when a glazer told me he was working on a job far from any medical facilities and he sliced his arm open on broken plate glass. Unable to stop the flow of bleeding, he used raw gasoline to cauterize the wound, and he said that while it hurt like Hell, it did the job.
      • SO you purpose using gas and motor oil to coat wood buildings / bonfires ? the fire hazard is the first, " this is not a good idea !" thought that comes to mind. The second is the smell, can you imagine the stink from dispersing bad gas from a sprayer all over a roof ? Then there's the pollution problem, heat will sweat the oil out of the wood and the oil will hit the ground with the rain. And lastly there is the $10,000 EPA fine for improper disposal of the oil and gas .
        Please don't " guess" at things concerning safety, and offer them as a solution.

        BTW Ceder shingles need no " protective coating", that's why Ceder is used in the first place.
        • "Ceder shingles need no " protective coating"

          they totally do, but good post otherwise.
          • Soaking posts in crankcase oil is a pretty standard early 20th century remedy against ground rot, termites, etc. You'll find this technique featured in old 1020s Popular Mechanics. Crancase oil also useful for it's anti-fungal properties.
            Loose hammer heads or axe heads soaked in crankcase oil will swell up the wood and get the tool tight.
            These is not much, or any dripout of oil as the wood pretty much drinks it up.

            The addeition of gasoline to the crancase oil will render it more spreadable by brush as in application to siding or thin coats onto lumber. The gasoline has a very quick rate of evaporation so that there will be very little to no dripout of toxics.

            Being eco-conscious is wonderful, but let's keep it real.

              Now we've used diesel with creosol as a wood preservative while making a cattle corral... You desolve the creosol in the diesel and paint it on or soak the wood in it and it will withstand insects and weathering for years~!

                I've preserved wood with old oil even brand spanky new oil.
                I've rot and bug proofed wood with antifreeze.
                It' is illegal in most states.

                If you have bugs in your cellar timbers antifreeze sprayed on will kill 'em when they chew on it.
                It doesn't degrade like most pesticides and doesn't have much of a vapor pressure so it won't contaminate the air.
                Probably illegal too.

                Everything that actually works, it seems, is illegal.

    I've reread your original post and seems like by now you probably have done something with those 'few' gallons of old, dirt and water infested gasoline but you can safely remove the water from the gas by pouring it in a glass container and you will see the water settle on the bottom of the jar and you can suck the water out with a bulb... Actually the dirt will settle out too and can sometimes be sucked out with the water and then a bottle of 'octane' booster purchased from the local hardware store can be added and the gas used in small engines and the sort, your lawnmower...
    I just rebuilt a carburetor on my four-wheeler and I use old gas in a coffee can to clean parts so I never like to just throw out old gas, too expensive if you know what I mean... Good luck :)...

    I think the I think the county HAZMAT collection suggestion s get top marks.
    • Hello all, I just wanted to let you in on how I get rid of my bad gas. First of all I have 5 kids and 4 of them have dirtbikes and or atv's so if they don't take care of there own machine I sometimes end up with bad gas in the garage. The first thing I do is put the bad gas in a one gallon water jug. Then I drive across town to my mother inlaws house and I sneak it into her kitchen. Then when she's not looking I pour it in her fish tank.
      Good Luck!
  • Keep it in an adequately marked container. Not for use in Gas operated Machinery.
    You ask why? Gas has a shelf life of about 4-6 months when not mixed or agitated
    with newer fuels. Why? Old gasoline "settles" out and certain oil based products
    evolve. The worst of these is Varnish. In large amounts it has solvent-like
    abilities, smaller amounts it takes on a property similar to partially dried polyurethane
    finishes. When it is used in gasoline engines or left in gasoline engines it
    can occlude filter screens, fuel lines and coat carbueration surfaces with a
    honey like glaze that when broken down and moved can gum up needle valves and
    fuel Jets. Best use Varnish solvents, weed killer mixed 1:2 with luke warm water
    used in a garden sprayer. Fire starter for burning branches and yard debris. It still
    has its aerosol ability so beware of flashbacks. Very few recycling centers accept
    used gas because of the previous reason.
  • i know this is an older post but seems the problem is timeless lot of interesting answers what about using seafoam? anyone use this before?
    • Unsu...
      Foam from the sea?
      Or SeaFoam Deep Creep?

      Before you go and spend a pile of dough on these sprays in the cans consider that maybe they are not worth the asking price.
      They might be if the can and spray are so convenient and your use won't ever justify buying the constituent components in pints or quarts or gallons - which is how you can buy 'em.

      But Spend a few minutes on the all seeing all knowing Google and dig up the MSDS sheets for these things and chase the CAS numbers down for the components. WD40, Boeshield T9, SeaFoam Deep Creep any of 'em.

      You'll find they are mostly all the same shit:

      Deoderized Kero, mineral spirits Naptha, Pump oil, Parrafin oil. Fuel Oil.
      In one case I found a company used a version of #2 Fuel oil that is refined to get the wax out and has a hard to track down CAS number for Jet Fuel, which is just de-waxed Kerosene. I suspect they chose that constituent because it would be tougher for the layman to figure out and no other reason.

      Anyway these things are not anything special, they are merely handy.

      For Bad Gasoline I've recently discovered this crap:
      They say it restores
