Red Line Racing oils provide more wear protection than motor oils for passenger vehicles, however, these products contain fewer detergents and are not suitable for street use. Red Line Synthetic Racing oils are reformulated for improved frictional properties. Red Line Racing Oils contain special detergents for improved lubricity providing reduced detonation at the limit. Polyol ester base stocks provide more stability and film strength when exposed to excess fuel dilution. Red Line Racing Oils each have no less that 2200ppm of zinc and phosphorus for anti-wear. Trust Red Line Oils to take you to the podium.
