Pennzoil GoldSynthetic blend motor oil provides better protection than conventional oil in severe driving conditions
The Proof is in the Pennzoil.
Pennzoil® Axle 80W-90 is a high quality, mineral axle oil for use in vehicle differentials and gears where SAE 80W-90, API GL-5 performance is needed. It offers improved low temperature flow compared to SAE 90 axle oil and full protection of hypoid gears in axles or differentials in vehicles where recommended by the manufacturer. The extreme pressure additives used bond to the metals surfaces to help prevent metal to metal wear where gears teeth slide across each other. Metal surfaces are also coated with an oil layer to help prevent corrosion in wet environments and in off road equipment.
A number of trucks and SUVs have limited slip differentials. Pennzoil® Axle 80W-90 contains limited slip additive sufficient for vehicles calling for SAE 80W-90, API GL-5 oil. Its limited slip capability provides controlled friction in limited slip axles, and provides a high quality performance all around.
