B2B BUYER GUIDE
Gear Oil Selection for Distributors and Fleets
Gear oil selection depends on the gearbox, axle or differential design, the required API service category and the viscosity specified for the equipment. GL-4 and GL-5 describe different performance requirements and should not be treated as interchangeable labels.
Review the stated application and viscosity on each product page. Before ordering, compare the current technical data with the transmission, axle or final-drive requirement for the target vehicle or equipment.
