Red Line® synthetic motor oils use the most stable synthetic lubricant base stocks available and are formulated for wear protection and friction reduction across a wide range of engine operating conditions. Red Line® lubricants are unique because they contain polyol ester base stocks, the only lubricant base stock that can withstand the incredible heat present in modern jet engines. Red Line® 20W50 Motorcycle Oil is the most popular choice for use in Harley® engines.
