I just use the old gas to start the burn piles. The oil in the stuff really lowers the volatility and gives me enough time to get away when throwing in the match. Straight gas go boom!! if I let the vapors spread too long.

Altavillan,

Unless the guy is buying a whole lotta gas at a time stabilizers just won't serve any purpose. In 1 to 5 gallon lots he should be able to use it up before it degrades. The stuff in most gas stations that have any kind of patronage gets turned around every few days, with some stations re-filling twice a day. I know because I used to fill the stations. Now if he lives out on a farm somewhere in Ohio then he just might have a bulk tank and need stabilizers for the other stuff running the gas.

As for dumping 5 gallons of mixed gas all at once into a car, that's silly. What's wrong with only doing a little at a time?
