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.

    75W140NS GL-5 A heavier product what works well over a wide range of loads and temperatures, contains additional friction modifiers suitable with clutch-type limited slip 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.

    Lightweight ShockProof A unique gear oil designed to lubricate racing transmissions and transaxles which see serious loads (not recommended for most syncro-type transmissions). It has excellent low-temperature flow which allows easier shifting when cold. May be used to obtain maximum power transfer in racing differentials which do not see high temperatures. Similar to a 75W140 gear oil, but with the lower internal friction of an SAE 30 motor oil.
    Used in most road-racing differentials with moderate power and dogring racing transaxles.

    Heavy ShockProof A unique lubricant containing a suspension of solid microscopic particles as an extreme pressure agent--unique solid dispersion which cushions gear teeth to help prevent tooth breakage and allows the use of lower viscosities.
    Recommended for heavily-loaded racing differentials and transmissions, Off Road racing and problem gearboxes. The viscosity characteristics allow the lubricant to resist throwoff and provide a film thickness similar to a 75W250 grade, while providing the same low fluid friction as an SAE 75W90.
