So I drained the gas out of my new project with a new fuel filter in the drain line. I've never seen gas so bad. damn near black / brownish about 2 gallons worth, amazing the damn thing ran on it to be honest.. anyways, need my gas can back for our riding trip next week. everyone says its fine to burn off a gallon or two with a tank full of fresh gas. but its a 400 mile road trip, and I don't wanna fup my car as its one of those grand designed fuel systems with a filter in the tank.. so other than burning it, any other good ways to dispose of it?
