Disposing of Old Fuel?

What is the proper way of disposing of old fuel? (I'm pretty sure I know what the Hongs would do, but I said proper.)

I need to drain a fuel tank. My guess is that the fuel is several years old. I'm hoping that the fuel gauge works ("Empty") because its a 22 gallon tank. If it's more than a couple of gallons, it will take me at least a full year to mix it in with fresh lawnmower fuel.

Camp fire?

lawnmower

I toss a gallon or two into the DD.

We've discussed this before. Dump it in the DD.

If you've got any appliance car or truck, this.

If you don't want to put it in your car or lawnmower etc, your municipal landfill/recycling center probably has a program for disposing of hazardous household chemicals, usually for free (so that people don't just dump them down the drain because they don't want to spend money). Mine takes old fuel, oil, paint, household cleaners, etc.

one pile of brush.. and whatever amount of fuel you have.. problem solved.

Burn it through your DD.

^this. That's the best method

I found that a carbureted RX-7 will run on 8+ year old fuel just fine. Pulled it straight out of the dead car and dumped it into the Mazda, worked just fine.

Or, if you are not that adventurous, or are merely cursed with exclusively owning piston-engined cars, you could find a shop heated by waste oil and donate it to them. Waste oil furnaces will generally burn up to a 25% mix of gasoline/oil with no ill effects, and it's hard for a shop to generate enough oil to meet their heat needs unless they're a LARGE busy shop.

I tend to put it in my co-workers vehicles 2-3 gallons at a time, then sell them fuel filters or injection cleaning services shortly after ;)

I can't wait to go back to work!

I enjoy my cars too much to risk running old varnish through them. I just dump it into my neighbors rat attracting shrub that I've been trying to kill for years.

JK, local disposal company will take it, along with old paint, whatever.

Another for Lawnmower.

Find a local repair place with a waste oil furnance. 4 or 5 gallons of gas into 250 gallons of waste oil just makes for more heat

It will eventually evaporate. The warmer it is the faster it goes. Have a 5 gallon bucket in the back of the garage that was full to the top in Oct. Now there is less than 2 gallons in there. If it wasn't winter I would have just used it up in the lawnmower. Since we haven't had any snow to speak of, the snowblower option is out of the question.

The doc is right. It's just old gas. Use it.

open fires need a permit in most towns.. easier to haul to free disposal sites..

Our local landfill facility has a separate building on site where you can take any hazardous materials free of charge. Check to see if yours has the same type of set up.

for a small quantity, you might mix the gas (petroleum distallate) with used motor oil (petroleum distillate) and put it in the used oil container at your local parts store

Fun fact: A lot of parts stores WON'T take oil that has gasoline in it.

I guess the oil dumped off at parts stores makes its way into ships and is used as fuel.

We get plenty of waste oil that way. We have a deal with the parts stores to send people our way if they have gasoline in the oil. The furnace burns about 50 gallons per week in the winter, we don't do nearly that many oil/fluid changes, so we're ALWAYS looking for more. (We joke about having a surcharge on people who come in with their cars 3 quarts low on a 4 quart system, but sad fact is, that kind of abuse already does come with its own surcharge)

OTOH, we were at a decent sized trans shop for a seminar, and were drooling over their in-building ~2000gal tank and auxiliary tanks, complete with pump lines and stuff. One building, 15-20 bays and the workload to keep them full, no problem keeping the heat machine fed.

My Urban Revolutionary Guidebook says to mix it with Tide laundry detergent and make Molotov Cocktails that stick better to the walls.

Hey, 5.0, that was a joke.

I mix it in my wife's car, one gallon to her full tank. She hasn't figured it out yet.

If ever I am blessed with old gasoline, I will dump it in the tank of my C-30 Dooley. At 9 mpg, it will burn a fair bit of it up in short order. Only slightly less thirsty is my John Deere lawn tractor, which might get some as well.

That's what I do.

Ya'll need to be really careful with your gasoline. When I ran the burn unit for a month, you guys' antics was one of my best sellers. I'll spare you the details, but you don't want to end up like that.

if you're worried about the quality of it then just use a couple of gallons at a time in the DD
