I have seen a "Biocide/ anti-fungal" intended for use in gasoline, at a local marine store. I have heard of it for diesel, but never for gas. Is it "Snake oil", or does it have some utility ?
Just saw in a JEGs magazine a additive the will make your exhaust smell like strawberries or rootbeer or 10 other things. $12.00 a bottle will treat 35 gallons.
