Red Line Motor Oils are designed to provide the highest degree of protection and cleanliness for your automotive, motorcycle, or marine engine. We use the most stable synthetic components available and formulate our products for wear protection across a wide range of engine operating conditions. Red Line lubricants are unique because they contain PE Polyol Ester base stocks, the only lubricants which can withstand the tremendous heat of modern jet engines. This high temperature stability makes our motor oil a necessity to properly lubricate a turbocharger or hot running engine. The synthetic base stocks have a natural multigrade property, which means that large amounts of unstable polymeric thickeners, like those used in petroleum oils, are not required to manufacture our multigrades.
