These products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers (except NS) for proper limited-slip operation
Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
Exceed API GL-5 specifications
Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
This is Red Line’s most popular product, most commonly used in rear differentials. It stands out from other oils for its very constant viscosity over a wide range of temperatures and operating conditions, providing excellent lubrication in all situations.
This is a GL-5 oil, which isn’t good for manual transmissions. GL-5 oils contain sulfurs that can damage synchros. It’s better to use GL-4 oils like MT-85 or MT-90.
