TECHNICAL DETAILS
20 WT (5W20): For drag racing, circle track qualifying, and racing engines designed for low-viscosity oils. Many drag racers run this oil for 10 to 12 passes before changing, with no sign of shear or loss of viscosity. Popular with bracket racers looking for extra performance.
30 WT (10W30): Suitable in well-balanced racing engines for sustained high-speed use where low internal friction is desired. Popular in bracket engines, 355 Sprint Car engines, and World of Outlaw 410 engines.
40 WT (15W40): For use where temperatures may be high and when a wide range in RPMs and speeds will be encountered.
50 WT (15W50): For use where extremely high temperatures may be encountered and when engine durability is the primary concern.
Red Line Racing Oils contain special detergents for improved lubricity and less detonation. Remember to change these oils more frequently than regular motor oils.
