    Technical Data


    RGO is an ultra-high-performance Racing Gear Oil engineered using the most advanced additive system and premium paraffinic mineral base oils. This combination of premium base oils and Torco’s race-proven additive system provides exceptional film strength cushioning gears and provides anti-wear performance without slinging off in high-speed and shock load applications. Our unique high adhesion polymers are used for increased shear stability and film strength. The balanced concentration of extreme pressure (EP), antioxidation, anti-corrosion, and anti-foam additives prevent fluid degradation and extend the life of critical racing driveline components.

    • High shock load and extreme pressure racing chemistry.
    • Exceptional film strength cushions gears in high-speed shock loading applications.
    • Outstanding thermal and shear stability.
    • Extends life of all driveline components.
    • Race grade formula with high concentration of extreme pressure additives.
    • Safe for yellow metals.

    Recommended for racing applications where extreme shock load, speed and temperatures are common. 80W-90 is recommended for differentials, transmissions, and transfer cases requiring SAE 80W-90, 90 GL-5 gear oil. 85W-140 is recommended for differentials, transmissions, and transfer cases requiring SAE 85W-140 GL-5 gear oil. 250 is recommended for dragster and severe on-road and off-road racing applications.

    For limited-slip or posi-traction differentials, use Torco Limited Slip Friction Modifier Type G (for all GM
    applications) and Type F (For everything else)
