RE: leftover gas

[Jim Buck]

Last year my 2 stroke outboard only used about 3 gallons of gas from my six gallon tank. I put fuel stabilizer in it but I'm kind of afraid to use it. I'd like to fill the tank with fresh gas and the proper oil mixture. Can anybody recommend what to do with the three gallons? I've thought of putting it in my truck but the oil in the gas worries me. Any experience or suggestions would be most appreciated. Thanks.

I have a one gallon tank. I also use about 2-3 gal/season, and I've put 1/2 gallon in the SUV tank before with no problem. Don't know about 3 gal though.

Hi Jim, I mix the 2-stroke gas with the gas in my F-150 and have had no problems. I add it to a nearly full tank and pour in 1-2 gal of mixed gas. Too much could damage a catalytic converter, that would be a costly mistake. However, oily gas diluted within 15-20 gal of regular gas should not cause any problems.

That's my humble opinion.

It always goes in my 1950s Ford 8-N tractor. That things would burn just about anything and not care all that much.

Lacking a vintage farm machine the above advice seems sound enough, Steve.

I use old gas in the lawn mower. Usually half and half old gas new gas.

I have a can of old gas that I have been trying to get rid of for awhile, living aboard full time means I dont have lawnmowers and such to stick it into. Have tried giving it away many times but of course no one wants it!

Burning the old 2 Cycle gas is a great idea, but where can one dump old gas without effecting the environment?

This is a good question in light of the ethanol issue

Since you used a fuel stabilizer, I would be inclined to mix fresh gas with the old gas and use it in the outboard. The biggest threat with old gas is by gumming up the carburetor. The fuel stabilizer would minimize that and the new gas would compound the cure.

A drop in octane rating may be a concern, but a two-stroke outboard is not a high compression engine, and the fresh gas should be adequate to prevent any knocking. If you notice any knocking, use a higher octane fuel for mixing.

The only other concern would be carbon build-up in the combustion chamber, but since a two stroke burns oil, I don't see that as a major concern, because it is inevitable anyway, and generally doesn't cause much trouble.

That's my two cents.

Gas stations have a waste portal you can poor into, they may charge you a couple bucks.

I can see posts 50 years from now..."I had to reach all the way back behind the PBBF, (portable beer-brewer/freezer) to replace my hydrocell pack! WAPITA!
