Quickare is a fuel treatment that can be used at every fill-up and will keep fuel fresh for up to 3 months. Specialized formula will maximize engine performance with all grades of gasoline and help control corrosion, gum, and varnish buildup and phase separation associated with ethanol-blended fuel. Regular use will also control moisture and corrosion problems associated with non-ethanol-blended fuel. Use in all 2 and 4-cycle fuel-injected gasoline engines including cars, trucks, motorcycles, ATVs, snowmobiles, marine engines, lawn mowers, and more. Safe for catalyzed engines. 1 oz. treats 10 gallons of fuel.
