Shell Spirax S4 AX 80W-90 Heavy-Duty Automotive Gear Oil

Shell Spirax S4 AX 80W-90 delivers dependable protection for gears operating under heavy loads and demanding conditions. Formulated with extreme-pressure additives, this multigrade hypoid gear oil helps reduce wear, resist scuffing, and maintain reliable drivetrain performance.

Its thermal and oxidation stability helps resist oil breakdown at high temperatures while controlling deposits around seals and bearings. Suitable for qualifying passenger vehicle and heavy-duty equipment applications, it provides reliable lubrication where SAE 80W-90 gear oil is specified.

Key Features & Benefits

• Strong load-carrying protection: Extreme-pressure additives help protect gear surfaces against scuffing and wear, even under demanding operating conditions.

• Resistance to heat and oxidation: Helps maintain lubricant performance at elevated temperatures and reduce harmful deposit formation.

• Cleaner bearings and seal areas: Helps keep critical surfaces clean to support reliable operation and minimize wear.

• All-season versatility: Multigrade performance can reduce the need for seasonal lubricant changes where ambient temperatures and equipment requirements permit.

• Potential fuel-economy benefits: Designed to reduce frictional energy losses and support drivetrain efficiency.

Applications

For suitable differentials, final drives, and other drivetrain gear systems requiring SAE 80W-90 and the applicable performance specifications. Use in transmissions, transfer cases, or steering mechanisms only where recommended by the equipment manufacturer.
