Choosing the Right Gear Oil
Selecting the right gear oil involves understanding your vehicle’s requirements and the environment it operates in. Consider the viscosity grade, type of vehicle, and compatibility with components. Synthetic oils tend to offer better performance and longer life, especially for high-performance or severe duty vehicles.
What is the difference between GL-4 and GL-5 gear oils?
GL-4 gear oils are suitable for vehicles with brass or bronze synchronizers as they have lower levels of active sulfur, which can harm these components. GL-5 oils have a higher concentration of extreme pressure additives, designed for higher load-carrying capacities, often leading to less compatibility with yellow metals.
Can gear oil affect transmission noise?
Yes, using the correct type and viscosity of gear oil can reduce transmission noise by providing better lubrication and reducing friction between components.
