Understanding the Differential and Its Role To appreciate the importance of differential oil , one must first understand the component it protects. Without it, the metal-on-metal contact would generate immense heat and destroy the system within minutes.
Differential Oil Temperature Management Strategies
Viscosity Grade Best For Typical Application 75W-90 Cold climates, daily drivers Passenger cars, light trucks 80W-90 Balance of comfort and performance SUVs, vans, older performance cars 85W-140 Heavy loads, high temperatures Commercial vehicles, heavy-duty trucks Signs of Degraded Fluid Over time, differential oil breaks down due to heat, contamination, and metal shavings from normal gear wear. Composition and Viscosity Explained Modern differential oil , often called gear lube, is formulated with a high-quality base oil and a complex additive package.
This is essential when turning a corner, as the outer wheel travels a longer distance than the inner wheel. Most manufacturers recommend a drain and fill every 30,000 to 60,000 miles, though severe driving conditions may necessitate more frequent service.
