    Every year about this time, I put my fishing boat in the water. I always have about 3 gallons of oil/ gas mix for the 2 cycle outboard left from last year. I am reluctant to run this after sitting all winter. I have heard that you can add it to a full tank of gas in your car and it will be so diluted it won't hurt anything. I'm not sure. Any ideas? Thanks

    If you car is carbureted, then sure, it should be fine.

    Fuel injected, I wouldn't take a chance.

    put some fuel stabilizer in the can of gas before you leave it for the winter, it works for my boat, weed eater, chain saw gas. i put some in every gas tank also and run it before i park it for the winter except for the cahin saw, it never seems to get parked.

    I've done it several times, works fine, just make sure it's "diluted" enough so it won't foul the plugs.

    DH says you might damage the catalytic converter, which could cost you big bucks if it stops up. Both in fuel economy, and replacement.

    He suggested that you consider burning it in the lawnmower, or an old gasoline tractor maybe.
    Or, just sweeten it with fresh gasoline mix, and burn it in the outboard.

    just a thought.

    The key here is finding a mechanica that will just bypass the cat converter for you. My MPG will go up, your engine power will go up, and no big bucks for replacing platinum parts in your car!

    We had a car with a carbeurator. Stupid BIL put his dirt bike 2 cycle gas (less than 1 gallon) in our car (4 cylinder, half tank of gas). The car smoked, ran rough, wouldn't idle right. Took 3 or 5 tanks of gas to get it to start running decent but it never did run right again.

    That depends. Some vehicles are very carefully engineered for the back pressure that the cat provides and altering the exhaust can throw the engine management system out of whack and it can have a detrimental impact on both mileage and performance. On older and simpler vehicles you can often get away with removing the cat or bypassing it but on newer vehicles sometimes it doesn't work out as well.

    Once upon a time they wouldn't pass you through vehicle inspection if the cat was removed. Some enterprising individuals took to taking old cats, gutting them, and welding a straight pipe through them. Looked to all the world like a functioning cat under there but in fact it was just a shell around a section of straight pipe.

    That's what I do. Every summer I pour my leftover chainsaw gas in the riding lawnmower and cut grass with it. Come fall, I pour my leftover weedeater gas in the riding lawnmower to haul wood to the porch. No waste here.

    I have a fuel injection car
    I have use old 2 stroke /cycle fuel in the car both in a emergency ( ran out) and to just to get rid of it ( old) but in both cases I filled the car up with gas after I put in the tank, as it dilutes the oil content of the 2 cycle fuel

    car still runs and no problems. however I my car is 10-15 years old. have no idea how it will effect newer model vehicles

    This qualifies as scientific proof that placing "less th[e]n 1 gallon" of mixed gas into an automobile is a suicidal proposition.

    Seriously, dump the stuff in your car, fill the tank with straight gas and continue loving life. The two drops of oil per gallon will do absolutely nothing whatsoever.
