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.
FEATURES & BENEFITS:
• 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.
APPLICATIONS:
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)
