Differential fluid, a lubricant vital for the proper function of a vehicle’s drivetrain, minimizes friction and wear within the differential. This component allows the wheels on an axle to rotate at different speeds, crucial during turns. Without adequate lubrication, internal parts would experience excessive heat and premature failure.
Maintaining appropriate fluid levels and quality ensures optimal performance and longevity of the differential. Neglecting this maintenance can lead to noisy operation, reduced fuel efficiency, and costly repairs. Historically, vehicle manufacturers provided general guidelines, but increasingly, specific recommendations tied to vehicle usage and operating conditions have become the norm.
