What to do with old gas and oil?

    I have about a gallon of pre mixed oil and gas in a plastic gas can that has been outside all winter long and I'm wondering what to do with it. I really don't want to put it in my engine (I'd rather recycle it and get some new gas) so what do I do with it?

    all of the oil recycling places here in California will not accept contaminated oil... so dont mix it in with your used/recycleed car oil because then you just have more contaminated oil.

    I suggest putting it in your bike and car a small amount at a time with fresh gas. Shouldn't hurt anything, just a little bit every tank until its gone.

    Burn it in your car. Just add several ounces at a time to a full tank. The 2 stroke oil will help lube your fuel pump.

    Yes, put it in your car, a little 2 stroke oil doesn't hurt in fact Pablo has reported an increase in gas mileage when he does it. I don't pay that much attention to my car gas mileage so I can't comment.

    Unfortunately I only have the one gas tank so I can't keep it in it until I use it up here and there in my car because I can't wait that long to ride my bike.
    What if I just add another gallon of fresh gas (it's a two gallon tank) and a new bottle of oil to the mix?

    Add to:
    a) car
    b) lawnmower
    or any internal combustion engine that will burn it up quickly.

    no... never put injector cleaner with your 2 stroke mix. Im no chemist but I dont think detergents and lubricants should be mixed togather.

    For the record... unless you ride very frequently, its easier to mix a small amount of fuel at time instead of a whole gallon or 5 gallon jug. I use a syrenge and a measured funnel with a valve I bought at autozone and pour it right in the tank. You can find very precise ratio calculators online that will tell you exactly how many ml of oil to gas.

    I got tired of old stale gas sitting in my garage... its better for your bike too. You shouldnt let mixed gas sit for long periods of time.

    I mean a fuel stabilizers.
    All the gas is all the same in the state for that octane. It when they put gas in to the tanker and the addivite is added when it changes. You can buy Chevron addivate in the parts store the same they put in the gas. You may what to check Home depot in the lawn tools. I remember seen a black stuff you add to gas to refresh it.

    Gasoline shelf life : According to Chevron.... "Gasoline stored in a tightly closed container in a cool place will stay good for at least a year. It is better if the container or gas tank is almost (95%) full. If the container or gas tank will be in the direct sun or will be heated above 80 degrees F. much of the time, add an aftermarket fuel stabilizer to the gas when you first buy it. Gasoline-oil blends for two-stroke cycle engines stored under the proper conditions will keep as well as gasoline itself."

    I wouldn't want to burn it in anything, just pour it over a pile of wood somewhere or in a barrel light up a ball of paper or something heavier and chuck it in heh. Invite some friends around for a hobo barrel fire bbq.

    Injector cleaners are used in diesels......

    do diesels have an internal oiling system... or does the fuel act as a lubricant???

    Just burn it or pour it on the ground and light it Dont be a **** hippy! If you really cared that much you wouldn't be riding a 2Smoke you would have a 5k 1speed like Kevin Bacon in Quicksilver and have a sweet spandex suit you dress up in so every one can see you smugglin grapes!

    Better yet write your name in the street and light it!:whistling:

    Or Best idea is to just put it in a can or jar and let it evaporate!

    If you have a chain link fence it is good to edge it with old gas....kills weeds. Here in Texas I like to use old fuel on fire ant mounds. Or you could dispose of it in your communities hazardous wast pick up. Most have them atleast once a year (I keep missing ours so I have 5 Gallons of Paint that is slowly drying out for regular pick up).I have heard of disgruntled postal workers bottling it and giving it as a christmas present complete with flaming rag on the top, but I would not suggest that. It is just wrong.

    If you aren't willing to burn it your MB then don't even think about your car.

    I like the above suggestions, bonfire, weedkiller, ant and bee control are good.

    I would check for water and contaminants, if clean cut it with a fresh gallon of gas and the appropriate amount of oil. A couple months shouldn't be a big issue.

    In a pinch I've put 2 stroke mix in my 4 stroke lawn mower without a problem. If you try to put it in a modern car you'll f*** up the emission senors and have the check engine light on till you pay a shop to turn it off via computer. Find a friend with an old pickup and they'll be glad for some free gas.Please don't dump it on weeds or burn in an open fire it really pollutes a lot.

    Most diesels have a dedicated pressurized oiling system. They do last a long time because they are often over built to handle the high compresion and combustion pressures. The rings and valves benefit because the fuel is essentially a light oil. (that's why diesels are referred to as "oil burners" by some)
