Amsoil Fuel Additives.  PI Performance Improver is the most potent gasoline additive available today. In engines with accumulated deposits it provides improved fuel mileage up to 5.7%, reduced emissions, restored power and performance, reduced need for higher octane fuel, reduced carbon rap and pre-ignition, provided better drivability and smoother operaton after only one (1) tank of gasoline.

For diesel burning engines, Amsoil offers Cetane Boost Diesel Fuel Additive, Diesel Concentrate, and Diesel Cold Flow Improver. Cetane Boost improves combustion efficiency to release all the power your engine has to offer. It improves low temperature starting, fuel ignition quality, and reliability. Cetane Boost raises Cetane 3 to 7 numbers.

Diesel Concentrate is a total system cleaner and lubrisity improver for all types of heavy and light-duty diesel engines. This product controls the problems created by EGR systems by neutrilizing acids during combustion, minimizing acidic cylinder wear, reducing the rate of TBN depletion and maintaining oil quality. It improves the oxidation and thermal stability of diesel fuel, improves fuel economy up to 5%, restores horsepower and protects against water contamination.  Completely compatible with all types of diesel exhaust systems.

Amsoil Cold Flow Improver is recommended for low temperature application below 40⁰F. It effectively modifies wax crystal formation to depress diesel fuel pour point and improve cold flow filtration properties. Lowers the cold filter plugging point by as much as 20⁰F and decreases the need for diluting #1 diesel with kerosene. It is compatible with all diesel particulate filters (DPF's).

Amsoil Motorcycle Oil, SAE 20W-50 Advanced Synthetic Motorcycle Oil Is recommended for Harley-Davidson, Buell, KTM, Ducati, Aprilia, BMW, Triumph and many other motorcycle engines. There are no friction modifiers added and this product is wet clutch compatible.
