Fuel Additives FAQs

Is it worth adding fuel additives to a vehicle's fuel system?

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.

How much fuel additive is needed per gallon?

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.

How often should I use AMSOIL P.I.?

AMSOIL recommends using AMSOIL P.I. every 4,000 miles. But I add a bottle every time I fill up my gas trucks, especially with the declining quality of fuel nowadays.

AMSOIL P.I. (Performance Improver) cleans your entire fuel system and restores up to 14% horsepower in one tank of gasoline. AMSOIL Performance Improver reduces noise from carbon rap and pre-ignition, controls pre-ignition "knock" and improves fuel economy. One bottle of P.I. treats up to 30 gallons of gasoline.

How do you use AMSOIL Gasoline Additives?

All AMSOIL Gasoline Additives are easy to use. Simply add to your tank right before filling up to ensure an even mixture. Double check the instructions on the bottle to verify proper dose recommendations. Most passenger vehicle applications will require no more than one full bottle.

Does AMSOIL Diesel Injector Cleaner work?
