Valvoline Light & HD Axle Oil 80W-90 is a heavy-duty axle oil formulated for buses, trucks, and commercial vehicles that require robust drivetrain lubrication. Enhanced with extreme-pressure (EP) additives, this oil provides superior gear protection under the severe loads and high torque conditions typical of heavy commercial vehicle operation.

The 80W-90 viscosity grade offers a practical balance between cold-weather capability and high-temperature protection. At low temperatures, the oil provides adequate flow for startup lubrication and smooth gear engagement, while at elevated operating temperatures it maintains a strong protective film that prevents metal-to-metal contact between heavily loaded hypoid gears and bearings. This makes it a versatile choice for vehicles operating across a range of seasonal conditions.

Valvoline Light & HD Axle Oil delivers comprehensive protection for both transmissions and differentials where GL-5 performance is specified. Its EP additive technology effectively prevents gear tooth wear, pitting, and scuffing, even under sustained heavy loads during uphill climbing, heavy towing, and fully loaded operation. The oil also provides excellent oxidation resistance that extends service life, strong corrosion inhibition for internal components, and effective foam suppression for reliable lubrication.

This axle oil is recommended for the complete range of commercial vehicle sizes — from light-duty delivery vans and medium trucks to heavy-duty long-haul tractors and city buses. It is an economical and dependable solution for fleet operators who need reliable drivetrain protection across their vehicle roster. With its proven formulation and wide applicability, Light & HD Axle Oil 80W-90 helps reduce maintenance costs and extend axle and transmission component life in demanding commercial transportation applications.
