Without the correct viscosity and additive package, the gears and bearings would suffer from excessive wear, overheating, and premature failure. Corrosion and oxidation inhibitors protect the metal components from moisture and the high temperatures generated during operation, extending the functional life of the fluid itself.
Cost Effective Differential Oil Options and What to Look For
The gear oil’s role is to separate these moving metal surfaces, minimizing friction and dissipating heat generated by the mechanical operation. In front-wheel-drive cars, the differential is often integrated into the transaxle.
One of the most common symptoms is a whining or howling noise that changes pitch with vehicle speed, indicating a lack of lubrication or worn gear teeth. Signs of Degraded or Incorrect Gear Oil Ignoring the differential fluid service interval can lead to a host of drivability issues and expensive repairs.
Cost Effective Differential Oil Options for Extended Gear Life
If the fluid is burnt or smells acrid, it has likely lost its lubricating properties due to heat and oxidation. Common viscosities for passenger vehicles include 75W-90, 75W-140, and 80W-90, with the "W" indicating winter cold-flow properties and the number after the dash denoting high-temperature viscosity.
