NGC - What to do with bad 2-stroke gas

[Gliderjohn]

I had about two gallons of mixed two stroke gas go bad on me. Never had that happen before. If it was regular gas I would use it in my old tractor as it will burn just about anything. Have a big bonfire? Could I maybe put about a quart at a time in tractor tank and burn it?

I would. I've done the same with some older 2-stroke fuel, used it in an old mower. Smoked a little, but not a problem.

YMMV, but that's me. I can be a hack sometimes and other times super precise and accurate with stuff. Depends on the love I have for a machine. Since I hate mowing the lawn, well... then my mower gets that same amount of love...

The amount of oil in modern 2 stroke premix is amazingly small, but even the old 5% mix will burn fine in a tractor. Heck, the oil actually seems to make the gas last longer, and will also likely make the tractor run better.

The other alternative is put it in a bucket and light it.

And then after it is lit how about shooting with a .243 form a safe distance of course in a dirt field at about dusk?

Yeah!
But if you have a .243, and a few gallon milk jugs, all you need to find would be some of those exploding targets.

Fill jugs, tape targets to jug, wait til dusk, shoot at 50 yards (unless your nose hairs need grooming).

I put it in baby food jars or their like and mix penetrating fluid outa it.  Great for dragging out with a brush for tractor lug nuts, implement hardware and such. Sometimes some kroil'll get thrown in, sometimes I'll have to cut it with a bit more gas or acetone if it gets gummy.

I quit messing with trying to use bad gasoline when I had an exhaust valve stick from it.

One of our major wildfires this year came courtesy of just that sort of shit-for-brains asshat.  There was a delay in bringing him in because they couldn't find a bus short enough.

Two gallons in a white bucket with a lid makes a nice solvent dip tank.  The more oil and crap you contaminate it with the better it sticks and penetrates built-on crud.  A guy I knew mixed his old gas with kerosene or stove oil and used it in a solvent tank with a pump.

[kevinkaren2011]

You could throw it into your neighbors yard to kill his grass,,lol..

I've used it for solvent cleaning drive chains or soak your chainsaw chain in it..

I mix up small quantities of mixed gas so I can get fresh more often..I always us 100% gas also.

[Gliderjohn]

Thanks for the suggestions. Several good ideas. I will try and refrain from any "hold my beer", youtube recordings. But if I do will post here first.

I put nasty old gas in my car. It care-eth not. A gallon of poor fuel in a tank of new is the cleanest, and maybe the only legal, way to dispose of it.

If it's so bad that it stinks, well, it will evaporate.

Got an old diesel car or truck (pre electronically controlled) or know someone with one?  They'll eat up old gas no matter how far gone like a fat kid with an ice cream cone.

I routinely have coworkers ask me what to do with their old mower gas/ two stroke gas or whatever.  My 260,000+ mile Mercedes 240D has gotten a lot of free fuel over the years.  Just throw a gallon or two per tank in and no worries.  If I see any sediment, I run it through a pre filter before adding it.

Does it make the engine run leaner as its drawing in 5% less combustable fuel each cycle??????

[Aaron D.]

Leaner?!

funny, the scooter world is full of people saying stuff like this. some people have "theorized" that too much oil will cause a seizure!

No, it would run leaner if the reduction in gasoline was taken up with air-but it isn't, it is taken up with cooling oil. Dyno tests back in the day showed 2 strokes ran cooler and made MORE power the more oil that was added.
And besides, it is SOOOO minor.

I drove tanker for 25 years. For spills we sopped 'em up with pads and let the gas evaporate.

Thanks for not pouring it on far ant mounds, gopher hills, etc.

"In the old days" the manual for a diesel car said to use one gallon of gas per tank of diesel in cold weather to help starting.

Most probably because of the amount of wax or paraffin, I think it is, in poorly refined diesel fuel.  This causes the diesel fuel to solidify and not flow properly in colder conditions

Certainly in Australia, which doesn't have extremes of cold, there used to be a difference between summer and winter grades of diesel fuel, for this reason.  I'm not sure what the story is now, with Aussie diesel down to 5ppm sulphur. I don't know if that extra refining affects the wax content.

I have a chuckle every time I read the fable on US diesel pumps "Ultra low sulphur content - 15ppm."  ;-)

 Uh , hmm , Jim old buddy , 2 strokes don't ... never mind

Don't use it to start a fire.

Also never use gasoline, in any amount, in a kerosene heater.  After a co-worker tried it many years ago, it was only a year of skin grafts before he was able to return to work.
