Red Line Gear Oils & Manual Transmission Fluids

Product images may differ from actual product appearance.

Red Line Gear Oils and manual transmission fluids are designed to give improved gear protection at high temps. They reduce differential temps 10-70°F. Efficiency improvements between 1-5% are typical. The synthetic base stocks and additives allow the gear oils to carry higher loads compared to petroleum lubricants. Try Red Line manual transmission fluids in your vehicle.

MT-90 75W90 GL-4 Popular in Nissan, Toyota and Mazda manual transmissions and transaxles as well as other selected applications, this is a 75W90 GL-4 Gear Oil that's slightly heavier than MTL. Provides excellent protection of gears and synchronizers and its balanced slipperiness provides a perfect coefficient of friction, allowing easier shifting.

    MT-85 75W85 GL-4 Recommended for Nissan 350Z and 370Z (also most Maxima, Altima & Sentra), Mitsubishi Evolution, Hyundai, and Kia applications. Many NV4500 truck transmission applications like Chevy Silverado and Dodge Ram. Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage. Offers quicker shifts, perfect synchronizer coefficient of friction. Recommended for GL-1, GL-3 and GL-4 applications, as well as where most special synchromesh fluids are specified.

    75W90 GL-5 Our most popular gear oil, this is the preferred product in nearly all car and light truck differentials, both conventional and limited-slip. 75W90 is preferred for most racing applications. It contains friction modifier which is recommended for limited-slip units. 75W90 Gear Oil can be used in many transmissions and transaxles; however, other Red Line lubricants have better frictional properties for rapid synchronization. Exceeds API GL-5.

    75W90NS GL-5 This GL-5-type gear oil doesn't contain the friction modifiers for limited-slip hypoid differentials. This makes the transmission synchronizers come to equal speeds more quickly, allowing faster shifting and much easier low-temperature shifting. Can also be used in racing limited-slip differentials where weak spring design causes too much wheel spin.
