The differential gears allow the car wheels to spin at different speeds, which is especially important when turning corners. Differential fluid protects the moving metal surfaces from friction and wear. As with all fluids, the differential fluid needs to be changed periodically. We recommend every 30,000 miles. Consult your owner’s manual for manufacturing recommendations for your vehicle.
