Fits select 1992-2026 Acura, AM General, Aston Martin, and Audi models.

Royal Purple Max Gear 75W90 is a high-performance synthetic gear oil engineered to protect heavily loaded gearsets while maximizing power transfer through the drivetrain. By utilizing advanced synthetic molecules, Max Gear significantly reduces friction and wear, even under the extreme squeeze film conditions found in high-torque applications, low-RPM operation, or sudden shock loads.

This formulation is specifically designed to improve fluidity in cold climates, ensuring immediate lubricity at startup. It is also completely noncorrosive to both ferrous and nonferrous (yellow) metals, making it an ideal choice for differentials and manual transmissions that require a 75W90 weight oil.
