Extreme Semi-Syn Gear Oil 75W/90 represents an advanced, next-generation gear oil engineered to provide superior lubrication for a wide range of applications. This includes differentials in cars, trucks, and tractors, as well as other final drives, transfer gearboxes, steering gearboxes, and manual transmissions.


Extreme Semi-Syn Gear Oil 75W/90 is designed to provide:

• Outstanding thermal and oxidative resistance

• Significantly enhanced longevity of oil seals

• Substantial improvements in durability for gear surfaces

• Remarkably improved corrosion protection for yellow metals in both wet and dry environments.

Extreme Semi-Synthetic Gear Oil 75W/90 features specially formulated oxidation-resistant paraffinic and hydro-treated base oils, meticulously blended with high-performance extreme pressure (EP) additives, anti-corrosion agents, and anti-foaming compounds. This unique composition is designed to guarantee extended operational longevity for transmissions and drive lines.

Extreme Semi-Syn Gear Oil 75W/90 uses the characteristics of these components to address the current strains put on modern gear oils:

  • Alterations in vehicle aerodynamics
  • Expanded utilization of driveline retarders
  • Enhanced “Power Density” for transmission and rear axles
  • Prolonged periods of slow speeds and high loads
  • Elevated ambient temperatures
  • Augmented horsepower
  • Extended warranties and reduced maintenance requirements


Extreme Semi-Syn Gear Oil 75W/90 meets or exceeds the following demanding performance requirements:

API GL-5 API MT-1 SAE J2360 MIL-L-2105D


Mack GO-J
