  • Torco SGO 100% Synthetic Racing Gear Oil SAE 250

    Select Your Package

    Torco SGO 100% Synthetic Racing Gear Oil SAE 250 is designed to maximize power efficiency and provide the highest level of gear protection under the most severe speed and load conditions. It is formulated using a combination of Group IV/V synthetic base oil chemistries and additive technologies providing high shear resistance and 4-5 times the film strength of conventional oils. This combination of base oils and extreme pressure chemistries offers superior wear protection, improved power throughput, longer component life, and prevents rust and oxidation.


    Features & Benefits

    - 100% Synthetic Formula
    - Superior shock load and wear protection
    - Increases power throughput
    - Reduces operating temperatures
    - A balanced concentration of race-proven chemistries
    - API GL-6

    Note: For limited-slip or positraction differentials use Torco Limited Slip Friction ModifierType F (for all applications except GM) or Type G (for all GM applications)

    Technical Data


    SGO 100% synthetic racing gear oils are engineered using high molecular weight Group IV and Group V mPAO and Ester base oils for exceptional film strength and fluidity. The high concentration of Torco’s proprietary Extreme Pressure, race-proven additive system extends the life of gears, bearings, and metal surfaces by quickly reaching and clinging to components during initial startup and will not sling off during severe speed and load. This combination of synthetic base oils, 0-5 SSI Polymers, and Extreme Pressure chemistries resist shear while protecting vital components, improving power throughput to the wheels, and resisting oxidation, foam, and rust.

    • 100% synthetic Group IV and Group V heavy mPAO and Ester base oils for exceptional film strength and
    fluidity to quickly reach and cling to components without slinging off during high speed or load.
    • The balanced concentration of Torco’s Extreme Pressure additive system provides superior shock-load
    and wear protection.
    • Forms a strong layer of iron-sulfide on gear surfaces.
    • The low coefficient of friction reduces operating temperature while improving power throughput.

    Commonly used in race vehicles including cars, trucks, desert and rock racers in extreme speed and load
    applications. 75W-90 & 75W-140 is recommended for use in differentials, manual transmissions, transaxles
    found on high-performance street, racing, heavy & light truck 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)
