Nobody likes old gas, your motorcycle included. Keep your end-of-season fuel fresh and prevent corrosion in your expensive engine by treating the fuel with conditioner and stabilizer before storing. Stabilizer prevents varnish buildup, gumming and all the other nasty things that stale fuel does to your tank and carbs. Good for all types of engines, from a lawnmower to a superbike. Easy storage, easy starting. Treats 17 gallons of fuel.
