Marathon Full Synthetic 75W90 Gear Oil is a high-performance lubricant engineered to provide superior protection, durability, and efficiency in today’s demanding driveline systems.

This 75w90 gear oil is formulated with premium synthetic base stocks and an advanced additive package. It delivers exceptional results in both extreme temperatures and high-load operating environments.

Whether you’re dealing with heavy-duty commercial vehicle axles or passenger car differentials, this 75w90 gear oil meets the standards of API GL-5 and MT-1. Its high viscosity index ensures protection over wide temperature ranges, while its low pour point guarantees excellent fluidity during cold weather.

This gear oil is specifically designed to protect critical components such as gears, bearings, and synchronizers. It resists oxidation and thermal breakdown under high stress, preventing sludge and deposit formation while improving long-term cleanliness and performance. With dependable seal compatibility, it reduces the risk of leaks while extending the life of seals and gaskets.

Marathon Full Synthetic 75W-90 Gear Oil also helps combat rust and corrosion in transmission and differential components. This is especially valuable for vehicles used in wet, off-road, or high-humidity environments. Its enhanced extreme pressure (EP) formulation ensures smooth shifting and robust wear protection, even under severe service or towing conditions.

For fleets or performance-focused drivers, this 75w90 synthetic gear oil also supports extended drain intervals—up to 250,000 miles. Its anti-foam properties promote consistent lubrication, while its thermal stability prevents viscosity breakdown at high operating temperatures.

Suitable for domestic and imported vehicles, as well as non-synchronized manual transmissions and transfer cases, it delivers long-lasting gear protection. If you’re seeking a high-performance gear oil 75w90 that performs across all conditions, this lubricant offers reliability.
