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.
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.
