Red Line Motor Oils are designed to provide the highest degree of protection and cleanliness which the lowest friction for your gasoline, diesel, motorcycle, or marine engine. We use the most stable synthetic components available and formulate our products for wear protection and friction reduction across a wide range of engine operating conditions. Red Line lubricants are unique because they contain ester base stocks, the only lubricants that can withstand the tremendous heat of modern jet engines. This high-temperature stability makes our motor oil a necessity to properly lubricate a turbocharger or hot-running engine. The synthetic base stocks have a natural multi-grade property. Red Line has superior long-drain capabilities and recommends oil changes in a normally functioning engine between 10-18,000 miles for gasoline engines, and 10-20,000 for diesels, or at least once a year, whichever is shorter.

Red Line racing oils have gained a reputation as the ultimate racing lubricant. Marketers of other lubricants unsuccessfully claim to be "as good as Red Line." Our lubricants are used by many teams who have found that the improved performance and equipment durability is the key to winning. Our 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 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 2-4% more power than an oil of similar viscosity, while providing much more protection. Each reduction in cviscosity grade allows 1-2% more power. To reduce the chance of detonation, our race oils contain very few detergents and are not recommende for street use.
