Red Line Racing Oils are reformulated for improved frictional properties with special detergents that improve lubricity and less detonation. Polyolester base stocks provide more stability and film strength when exposed to excess fuel dilution. Red Line race engines oils have no less than 2200ppm of zinc and phosphorus for antiwear. Red Line's Racing oils provide more wear protection than standard motor oils for passenger vehicles, however, these products contain fewer detergents and are not suitable for normal day driving use.
