It has been proven on-track to bring down high engine oil sump temperatures by 20 degrees F, which speaks directly to its ability to reduce friction, promote power and inhibit wear. Such engines include vintage and classic motorcycles, often equipped with air-cooled engines, and specifying straight grade SAE 60 oils. Rust inhibition is is especially important for engines subject to frequent short-trip operations or frequent periods of storage.
Acid neutralization protects engines from damage caused by corrosive by-products of combustion.
