R31-10404-6PK Description:Red Line Oil's 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 Race Oils 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 stock 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 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 Race Oils allow 1-3% more power than a similar viscosity, while providing much more protection. Each reduction in viscosity grade allows 1-2% more power. To reduce the chance of detonation, Red Line Race Oils contain low detergant amounts and are not recommended for street use.
