Description
SHELL SPIRAX S4 AX 80W-90
Heavy-Duty Extreme Pressure (EP) Automotive Gear Oil SAE 80W-90 for Hypoid Differentials, Final Drives, Transmissions & Heavy-Duty Equipment
Product Description
Shell Spirax S4 AX 80W-90 is a premium mineral-based extreme pressure (EP) automotive gear oil designed for heavy-duty and severe-service applications. It is formulated with high-quality base oils and an advanced sulphur-phosphorus EP additive system to provide excellent load-carrying capability, wear protection, thermal stability, and oxidation resistance.
The SAE 80W-90 multigrade formulation provides reliable performance across a wide temperature range and is suitable for heavily loaded drivetrains, including hypoid gears, differentials, final drives, transfer cases, and manual transmissions where API GL-4 or GL-5 performance is required.
