Frequently Asked Questions
85W-140 gear oil is thicker, offering higher protection under extreme load conditions.
Typically, gear oil should be changed every 40,000–60,000 km, but always refer to your vehicle’s manual.
Consider viscosity grade, gear oil price, and manufacturer recommendations for your car or tractor.
Old gear oil loses lubrication properties, causing increased wear, overheating, and possible transmission failure.
