Red Line Synthetic Racing Oils have gained a reputation as the ultimate racing lubricant. Marketers of other lubricants unsuccessfully claim to be "as good as Red Line Racing Oils." Our lubricants are used by many teams who have found that the improved performance and equipment durability is the key to winning. Red Line race oils are made with the most thermally stable synthetic base stocks available and provide the best high-temperature lubrication and a higher film strength than any petroleum or synthetic product marketed. The ability of Red Line Racing Oil to lubricate hot metal has enabled many cars to not only finish, but to win races after losing coolant, without serious damage to the engine. Even though Red Line Race Oils are straight grades, their low-temperature properties make them exceptional multigrades. Red Line Racing Oils allow 2-4% more power than an oil of similar viscosity, while providing much more protection. Each reduction in viscosity grade allows 1-2% more power. To reduce the chance of detonation, our race oils contain very few detergents and are not recommended for street use.

• SAE 10 (0W10) - For drag racing and circle track qualifying where the lowest internal friction is desired. Many drag racers run this oil for 10 to 12 passes before changing, with no sign of shear or loss of viscosity.

• SAE 20 (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.

• SAE 30 (10W30) - Suitable in well balanced racing engines for sustained high-speed use where low internal friction is desired.

• SAE 40 (15W40) - For use where temperatures may be high and when a wide range in RPMs and speeds will be encountered.

• SAE 50 (15W50) - For use where extremely high temperatures may be encountered and when engine durability is the primary concern. SAE 60 (20W60) - For supercharged alcohol engines like NHRA and IHRA Top Alcohol and Pro Modified classes.

• SAE 70 (70) - Traditionally used by NHRA Top Fuel, fuel Funny Car, and Nostalgia Top Fuel teams.
