Fuel Additive FAQs
Adding fuel additives to your vehicles or equipment can help protect your machines against low quality fuel and improve performance. AMSOIL fuel additives have been rigorously tested and proven to fight corrosion, improve fuel lubricity, increase horsepower, and much more.
AMSOIL Upper Cylinder Lubricant was tested and shown to deliver 18% more lubricity than Lucas and 20% more than Sea Foam. AMSOIL P.i. restored up to 14% horsepower based on third-party testing in a 2016 Chevy Silverado. And, testing AMSOIL Diesel All-In-One was shown to significantly improve lubricity in diesel fuels found all across the U.S., which results in improved wear protection.
The amount of fuel additive per gallon of fuel varies between different additives. Check the bottle to know precisely how much you need. For many (not all) AMSOIL products, it's recommended that 1 oz. of additive treats 2.5 gallons of fuel.
