Disposing of old gasoline?

I was about to empty the tanks of both of my old Fiat Spiders. Neither car has run in about 6 or 7 years, maybe 8. When I drain the tank, how do I properly dispose of the old gas? I assume it's no good, so I can't use it.

Bonfire!

Most parts of the country have provisions for hazardous waste disposal, without knowing where you live I'd suggest checking with your local waste disposal or city government. Another possibility is to do a search using this website: http://earth911.com/recycling/hazardous/

Depending on how bad the gas is, you may be able to use it up in your regular car - just mix in a gallon with each tankful of fresh gas and it will be gone pretty soon.

IF you filter it first and mix it with new gas you should be able to burn it in any gasoline engine. I would prefer a lawn mower or something similar.

Are your yard implements less picky about fuel? If it hasn't turned to varnish, you could use it in those.

I agree with the whole mix and use in yard implements although I've never tried it with anything that old. I've mixed 3yr old gas with two stroke oil and run chainsaws & weedwackers though.

Yup, throw the old fuel on the tire pile n light 'em up on Earth Day.

Put it in your DD.

1/2 and 1/2 with new and into the lawnmower or snowblower.

Yep, lawn mower or snow blower. Works every time.

I have put 4 year old gas into my Miata and RX-7 a gallon or 2 at a time. It worked fine.

Have some annoying tree or weeds around your house? Pour it on them and give it a week or so and thet'll be gone.

I just top off my lawn mower or DD if I've got 3/4 tank of fresh gas in it already.

I saw an ad on craigslist with someone giving away old gas. They said some... I dunno. Something about diesels and they like to add a little gas to it for some reason and old gas is fine for that?

Meh. Worth a shot.

You'd be surprised how fast it evaporates on a hot day layed out on cookie sheets, oil catch pans, newspaper, etc.

Interesting to hear the replies. I'd have guessed that with gas that is 7-8 years old, nobody would recommend using it in any combustion engine, even if mixed with fresh gas. Wouldn't it be pretty goopy by now?

Briggs and Stratton powered lawnmowers and snow blowers would just about run on urine I think. Mixed with a little fresh gas I wouldn't hesistate like I said earlier. All of the volitiles would be out of it so the fresh gas helps with stsrting etc.

I wouldn't put it in a car though.

Add 1 gallon of old to every fill up on the DD.

Plus one on filtering it using a coffee filter and then putting it to use.

However, after trying to use 7 gallons of gas in a lawn mower, I wound up using the last 4 gallons in my daily driver. I only have half an acre, though.

put in old five gal plastic can set by your curb watch it disappear, keep daughter inside during this process

I've been running my lawnmower for about 2 years on 5 gallons that came out of my old accord's tank when i swapped the pump. I have a pretty small yard lol. The mower doesn't seem to mind.

storm sewer...

Here in CA, that is a hefty fine if you get caught dumping it in the sewer. I have used it as week control at a house I was renting, but do not recommend this as the odor lingered for quite a while. If you can use it in a lawnmower or similar, go for it. If older carb vehicle, mixed in small amounts may be OK, but my Dirt bike does not like it one bit. As for Diesel, I have seen an owner of a BMW diesel (before they were imported here) put 2 gallons of super, 1 qt of marvel mystery oil and top off with diesel at least once a month. I was kinda surprised that his oil was not black (like most diesels) but looked like most gasoline cars when I had to check it.
