Red Line uses the most stable synthetic components available and formulate their products for wear protection across a wide range of engine operating conditions.  Red Line lubricants are unique because they contain PE 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, which means that large amounts of unstable polymeric thickeners, like those used in petroleum oils, are not required to manufacture  Red Line multigrade oils.  A motorcycle transmission will completely tear apart these polymeric thickeners which are used in petroleum oils and many synthetics, causing rapid loss of viscosity, which can result in inadequate lubrication.  Red Line Motorcycle Oils are completely shear-stable. In addition, Red Line provides enhanced zinc and phosphorous antiwear additives for the best wear protection available, and friction reducers designed for perfect clutch compatibility.


Because Red Line oils rely on the polymers natural multigrade properties you can use a lower grade oil in your engine without damage.  If your engine requires 10W40, you can safely run 5W30 without any worry of oil film breakdown.  For every single lower grade viscosity of oil you can expect a 1-2% power increase from the reduced viscosity.  Red Line 5W30 oils meet the API requirements for 10W40 oil.  The levels of zinc and phosphorus blended into these lubricants are among the highest in the industry and combine well with Red Line's chemistry, designed to seal piston rings for more power, fight fuel dilution, extend drain interval and provide stronger film strength over a range of temperature.  This oil also features lower levels of friction modifiers for superior wet clutch operation.  Excellent thermal stability, oxidation resistance, cleanliness, and ability to lubricate hot metal make Red Line High Performance Motor Oil a superior lubricant.  Recommended for JASO MB, API SJ, SG, & SH.

Viscosity recommendations:

• 0W20 is the lightest oil available. Recommended for new cars by several manufacturers for maximum fuel economy.
• 5W20 is specified in many new car owner's manuals for better protection at start-up without sacrificing economy.
• 5W30 provides the best lubrication on start-up and reduces turbo lag. Best choice for maximum power and economy.
• 5W40 provides more power and economy than a petroleum 5W40 or 10W40, while providing 25% thicker oil films.
• 5W50 protects high-performance engines like the 5.4L Supercharged Ford engine in Ford GT and Shelby GT500, especially in hot climates.
• 10W30 provides excellent economy and power while providing thicker oil films than a petroleum 10W40 oil.
• 10W40 is the best all-weather viscosity. Oil film thicknesses exceed that of 20W50 petroleum oils when hot but flow much better when cold.
• 10W60 is specified for newer BMW M-series such as E46 M3 and E60 M5.
• 15W50 and 20W50 offer the ultimate protection at high temperatures and are especially recommended in air-cooled, turbocharged, and Mazda rotary engines.
