2005-2010 Corvette Motor Oil

Royal Purple® Motor Oil is a tough, long life, high performance oil that delivers superior protection and enhanced performance to gasoline and diesel engines. It gains its performance advantages from a blend of synthetic oils plus Royal Purple's proprietary, synthetic Synerlec® additive technology. This technology is the force behind Royal Purple motorsports' exceptional performance. All Royal Purple products have super-tough film strength, outstanding viscosity stability, a very low coefficient of friction and tenacious adherence to metal surfaces. This enable engines to produce more horsepower and torque with less wear over much greater periods of time. Royal Purple lubricants have the ability to reduce heat from friction as a result of incredible film strength, thereby increasing part life. Royal Purple's motor oils are API certified and will not void new car warranties. Plus they are compatible with other mineral and synthetic motor oils.

Red Line Engine Oils are designed to provide the highest degree of protection and cleanliness with 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 polyol ester base stocks, the only lubricants which 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 multigrade property. Red Line has superior long-drain capabilities and recommends oil changes in a normally functioning engine between 10000 - 18000 miles for gasoline engines, and 10000 - 12000 for diesels, or at least once a year, whichever is shorter.

5W20, 5W30 AND 5W40 - Provides the easiest startability and lubricates fastest on startup. Reduces turbo lag and provides more power and economy in a properly functioning engine, while providing 25% thicker oil films than a petroleum of comparable viscosity.

10W30 - Reduces turbo lag and provides more power and economy in a properly functioning engine, while providing thicker bearing oil films than a petroleum 10W40.

10W40 - Best all-weather viscosity grade. Provides oil film thicknesses greater than a petroleum 20W50 in hot weather and exceptional flow properties in cold weather.

15W50 AND 20W50 - The ultimate in high-temperature protection. Recommended for hot-running engines, especially air-cooled. Provides 25% more bearing viscosity than petroleum 20W50's.

15W40 - Diesel Engine Oil is highly resistant to thermal breakdown. Provides double the detergency and acid neutralizing ability of conventional petroleum oils for maximum engine cleanliness.

Red Line Race 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-temperture lubrication and a higher film strength than any petroleum or synthetic marketed.  The ability of Red Line to lubricate hot metal has enabled many not only to 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 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.

SAE 20 (5W20) - For drag racing, circle track qualifying and race engines designed for low-viscosity oils.

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 durablility is the primary concern.
