disposing of old race gas

I have between 1-2 gallons of gas from a race kart that I don't trust is fresh enough to use. Some has oil mixed in and some is still straight VP110. How do I get rid of this stuff?

I dump all my boat gas into my lawn tractor tank. The trick to keeping the two stroke fuel from fouling the plugs is to add a splash of acetone.

Put it in your car or truck and run it. If you're fouling plugs from using premix in a 4 stroke, you have a problem.

Acetone? Really? Where do you people get these crazy ideas from?

Unless it's a the fuel is very dilluted, don't burn it in your car- VP110 is leaded. At least a modern car. Mower is a good idea- not much will be affected by the lead. Dillute the oiled fuel as much as you can, to keep the smoke down.

Just run it in your lawn equipment. You could mix a gallon in a tank of gas in your car and probably be ok. If you dont want to use it, just set it outside with the jug open and let the gas evaporate. Dispose of the remaining oil as you normally would.

Playing with solvents is bad and dangerous if you don't know what you are doing. If you want some acetone in your tank, pour in a bottle of Seafoam.

I have a huge bonfire every year and use all my bad gas as an accelerant. Lighting it is tricky, the last two times I used a flaming arrow.

Acetone helps keep the oil in suspension and also helps get the slow gas lit.

How does the oil fall out of suspension of gasoline? Even if the specific gravities were different, is it really that much of an issue? (Speaking of gasoline, which is oily, vs. methanol, which is watery. Been too long since high-school chem to remember which is polar and which is nonpolar)

Acetone is, by some happy accident, miscible with polar and nonpolar, so it does act as a good way to keep oil suspended in alcohols.

I realize using acetone in fuel is controversial to some folks but it truly helps keep the plugs clean. It wont boost performance and it wont increase your MPG but it keeps the plugs spotless.

The bad.. Acetone will dissolve the coating on cork floats and you don't want to use it on older two stroke engines with a lot of carbon build up.

Here, hold my beer and give me your lighter!

This may, or may not be, how this situation is handled at Aussie's Compound...Boom

Pour it into a plastic milk jug. Wrap tightly with about 5 rolls of duct tape and 1 M80. Place inside 55g drum. Light M80. Run like hell.

I am not a "look at me" type person, if you want more details or to see what I did you have to ask.

Here is last years bonfire. This years video will be better but I don't have it up yet because it just happened yesterday.

Edit: Since no one comented on the video I won't bump this thread for this years video that will be available soon.

Dump it in the lawnmower.

What if you have some gas with a little water in it? Siphon out all but the last couple inches (where the water is) and dump it in the DD? I have approx 20 gallons to get rid of. All my lawn equipment is manual/electric and my car is diesel. All that's left is boats and the girlfriends Corolla.

That's some height, how much old gas was used in the 2014 bonfire?!?

Any you know this why?

Fire Pit!*

*Please note that at the time of doing to, I was removing the "empty" rust-addled fuel tank on my CSX, and it ended up having about 5-10 GALLONS of old, orange gas in there. Much of it spilled out and I had quite the contact high. I decided to dump the rest into various containers over the fire pit in my backyard. Later that night, we set it on fire using even more of the rusty fuel, and there was quite the fireball. Not one of my better life choices.

It was about 4 gallons of bad gas and 2 gallons of some unmarked liquid I found in the garage that was highly flammable. I thought it was too dangerous to transport so I figured incineration was the best was to dispose of it.

Nice job.

Bonus points for any home video that includes both a Radio Flyer wagon and fire.

I run my old kart fuel in the yard equipment. The snow blower seems to run pretty well on 110 octane. IIt's exhaust also then smells a bit like my kart, which makes me smile when it's 20 below zero and I'm blowing out another 6-8 inches of snow.

Might work as an interesting tire-softener, too.

I've used 50/50 Xylene/Toluene. I bet gasoline-soaked tires would be pretty fun when you "light 'em up."

For fun and show, sometimes drag racers would put gasoline instead of water in the waterbox.
