While motor oil gets most of the attention, differentials and transmissions are just as critical to truck performance. These components face extreme pressure and heat during heavy hauling. Preventive maintenance with AMSOIL synthetic gear oils ensures these systems remain reliable and efficient.

Stress on Differentials and Transmissions

Heavy loads put enormous stress on gears, bearings, and fluids. Conventional oils shear down quickly, losing their ability to protect against metal-to-metal contact. Heat accelerates wear, leading to premature failures and costly repairs.

Why Synthetic Gear Oils Excel

Synthetic gear oils maintain viscosity under heavy loads and resist oxidation. They form a strong lubricating film that reduces friction and wear. Their additives protect against corrosion and help manage heat, extending component life.

AMSOIL Gear and Transmission Protection

AMSOIL Severe Gear® Synthetic Gear Lube is engineered for extreme pressure, making it ideal for heavy trucks. It resists thermal breakdown, protects against rust, and extends drain intervals. AMSOIL Synthetic Transmission Fluids, such as Torque-Drive®, provide superior protection for automatic and manual transmissions, ensuring smooth operation and durability under stress.

Preventive Maintenance Tips

Fleet operators should include gear oil checks in routine maintenance schedules. Using AMSOIL products across differentials, transmissions, and drivetrains ensures complete coverage. Pairing with AMSOIL Ea® Filters and diesel oils creates a comprehensive protection system.

Benefits for Fleets

Synthetic gear oils reduce component failures, minimize downtime, and improve efficiency. Extended drain intervals save money and reduce labor demands. Fleets that rely on AMSOIL see longer service life and lower maintenance budgets.

Differentials and transmissions are vital to heavy truck performance. AMSOIL synthetic gear oils deliver the durability and heat resistance needed for extreme conditions. Preventive maintenance with AMSOIL ensures these critical systems stay reliable and efficient.
