How long does fuel last with stabilizer?

With fuel stabilizer, your gasoline stays fresh and usable for up to 24 months. Without it, gasoline begins to break down and form gum within 3-6 months of storage.

Is this safe for all engines?

Yes, it's compatible with all gasoline-powered engines—cars, trucks, motorcycles, boats, ATVs, generators, and lawn equipment. It works with both ethanol and traditional gasoline.

One gallon treats up to 480 gallons of fuel. For most vehicles and equipment, you'll only need a small amount added to the fuel tank before storage.
