Best Uses for Old Gasoline?

Sometimes I end up with old gasoline despite my best efforts. I know, I know, I should automatically add fuel stabilizer as soon as I get it. But even that has limits.

What should i do with it? I'm certainly not dumping it on the ground.

I use some in an old hand mower, mixed with fresh gas and fuel stabilizer. But I won't use it in any good equipment because of the risk of gumming up the carburetor.

I do have an old MSR XGK camping stove that can handle it. Maybe that's the best move?

What do you folks think?

I tend to dilute with good gasoline and put it in my mower/wacker/pressure washer as I need to use them.

I have an older vehicle and would trickle some into it if it wasn't too old. If anything it will inspire me to change the fuel filter more often than not.

Back when I still had a petrol car (old 4WD Corolla wagon, real workhorse) I would put about half a liter of old fuel into a full tank. I figured since the dilution rate was 1:80 at that concentration nothing would cause an issue.

Howdy,
I also have just mixed in with my running vehicles fuel. I have even put old fuel mix from 2 cycle engines in my running vehicles, usually something like 10gal to 1 gal or less(old fuel).  

I use it first for cleaning tools, and/or motor parts, collecting it an open basin.  I pour that back into a gallon jug, and use it again for lighting burn piles during spring fire abatement.

There seems to be a consensus about using it in vehicles (in very small ratios compared to fresh gas).

Though personally, I would never add any gas+oil mix to fuel in a modern vehicle. That could seriously overheat and damage the catalytic converter, and they ain't cheap.

You can throw some in a diesel tank and run it through a diesel engine with no problem,
as long as it doesn't have water in it.
You might want to add some 2-stroke oil to compensate for putting such a thin fuel in there, add lubricity, thicken it up some.
But that's a good idea even when you put diesel in the tank.

There is another post about this and someone didn't like my idea but wouldn't say why.
But it's pretty common to mix things into diesel fuel.
Old gas is better than some stuff they mix with diesel.
ATF, vegetable oil, used motor oil, old gas especially old 2-stroke gas because it already has the lube in it, etc.
