Tomatos grown in gasoline soaked ground... Hummmm!!!

You could always mix it up with fresh two cycle gas a little
at a time. No valves to get stuck. Might run a bit crappy though.

I would again mix it either with fresh gas and run it in a lawnmower or

snowblower.

OR

Use it as a nice good weedkiller. Just pour it in small amounts.
Enough to kill the grass but not enough to soak in a do some
soil damage. You might be even able to use it in a spray bottle to
kill the weeds....
