    Probably a little late on this, 15 years is a long time. I pus some old gas in my tractor. I will never do that again.. the old gas gummed up the valve stems real bad. Took a long time to get it running right again. Some one mentioned week killer. The old gas stink stays around a long time. Stan

    If it is sealed up, I don't see what it would have happen, other than maybe depositing most of the gum in it, as someone mentioned long ago in the thread.

    If the volatiles in it can get away, then maybe it would degrade But a decent seal ought to prevent much of that. "Gasoline" of the old type was Ok in the ground for millions of years. Maybe modern "cracked" gasoline has enough odd molecules to degrade more. I have heard that, but not from any source with "sound science" behind it.

    With no headspace, there would be minimal entry of water vapor, which otherwise would be sure to get in as the air expanded and contracted. Somehow things that hold pressure often fail to hold a vacuum. Depends on the "seal direction".

    I worked at a manufacturing plant awhile back where the gas from an old leaking underground gas tank was migrating toward a water well. The company hired a professional company to come in and correct the situation. They pumped our the old gas, removed the tank, and then dug up the contaminated soil and placed it on large tarps and turned the soil every couple of days until the gas was vaporized by the sun. Then they put the same soil back into the hole that the tank came out of. Makes me wonder if you couldn't just place the tanks in the sun with caps off and let it vaporize??

    Use it 50/50 with fresh gas in whatever you drive or run. Small equipment or tractors will eat that stuff up. Heck I used to run old 50:1 gas/oil in my Sears 12hp, it ran just fine Just be sure you don't get sediment or water from the old cans. Even bad smell gas will burn.

    I'm with BCRider. Burn it in your car or whatever you have that uses gasoline. Just mix it like half and half. You won't have any problems at all. I have experience with using old gas.

    Just a thought- if that gas was left in a carb for a while, it would varnish up the jets, etc. If left in a can, it could varnish up the inside of the can, but the fuel itself might be ok. Getting it through a fuel system fairly quickly would probably not cause any problems at all. And we all know how quickly we can go through a tank of gas-

    The other thing that came to mind was to filter it before diluting in into fresh gas in the vehicle. I'll bet you would find a lot of crap in the filter by the time you're done using it up. So- what to use for a filter?

    The smell should give you a pretty good idea if the gas has gone bad.
    Try some in an old lawn mower.

    I'll take a couple cans if your looking to part with them.

    He doesn't want to get rid of the cans !!

    Run a 20ft aircraft cable through the handles, padlock it to the truck and leave a funnel, so they'll take the gas and leave the cans.

    They'll also probably still be at the scene of the crime, considering they just topped off with 15 year old stale gas.

    Pour about half a can in your car or truck tank, (gasoline engine) and it will be so diluted thay you will never know. Back in the 70's when I was working with aircraft instruments, the cleaning specification was revised. Benzine was found to be carcinogenic and was replaced by trichloroethane 111. We had a couple of gallons and I put it in my tank. All of it in a tank with only about 4 gallons of petrol (gas) was a big mistake, the engine pinked badly (preiginition?) and I had to top up with high octane and drive carefully.

    I've got enough old junk around here still running that I could make use of it. Shame you're too far away.

    Know anyone with an old tractor? They could mix it 50/50 with fresh gas and run it.
