Ensure robust protection and smooth operation for the demanding gearboxes and differentials in your classic or heavy-duty import with Motul HD 80W-90 Gear Oil (P/N: 105781), available at Straight Six Imports. This high-performance, mineral-based Extreme Pressure (EP) lubricant is specifically designed for transmissions and differentials operating under high loads, shocks, and elevated temperatures.

The 80W-90 viscosity provides an ideal balance of reliable lubrication at cold start-up and a thick, protective oil film under strenuous operating conditions. The robust EP additive package (API GL-4 / GL-5 compliant) is crucial for protecting the hypoid gears often found in rear-wheel-drive differentials (such as in the Nissan Z, Toyota Supra, or Mazda RX-7) and for use in manual gearboxes requiring a high level of shear stability. Motul HD 80W-90 is the dependable choice for maintaining reliable gear shifting and component longevity in older performance vehicles and heavy-duty applications where a high-quality mineral or semi-synthetic GL-5 fluid is specified.
