I found that adding old gasoline to my Farmall Cub tractor caused severe
valve sticking. I recently talked to someone removing heads from an air
cooled VW who had done the same thing. It is highly variable, you may very
well be able to mix it with fresh fuel and burn it without trouble.

I have a couple of gallons of old gasoline, probably at least a year old.
I suppose I could dispose of it properly, but I was wondering of it could
be "revived" somehow or used instead?
