It maintains its viscosity and film strength even when the internal temperature of the differential rises. This heat resistance prevents the oil from breaking down into harmful byproducts or forming sludge.
Highway Cruising Efficiency with Synthetic 80w90 Gear Oil
Synthetic 80w90 formulations utilize carefully engineered molecules that offer superior uniformity compared to conventional mineral oils. Furthermore, the oil's resistance to shear forces ensures that the viscosity remains consistent even under extreme pressure.
The "90" rating reflects the oil's viscosity at high operating temperatures, ensuring it maintains a stable film thickness to prevent metal-to-metal contact. This is particularly beneficial for vehicles used for towing or hauling, where gearboxes are subjected to immense pressure.
