Originally posted by CJ3Flyr True but you'd have to buy it the summer in some places and in others it's not availible as true, pure (with an incredible shelf life) gasoline. EPA's seasonal requirements and the addition of alcohol and other additives. That applies to all the gas including that from the BP. Coleman fuel and 100 Octane race gas are about the purest, longest lasting gasoline on a consistent basis.
Shelf life seems to be very important to you so here is a product that is a one time device that insures gas stays fresh!
