85w140 Spirax S4 AX Gear Oil 20 Liter Pail

Shell Spirax S4 AX 85W-140 Heavy-Duty Gear Oil — API GL-4 / GL-5 / MT-1

Shell Spirax S4 AX 85W-140 is a premium multigrade gear oil engineered to protect drivetrain components under heavy loads and demanding operating conditions. Its extreme-pressure additives help minimize wear and prevent scuffing, providing dependable lubrication for suitable heavy-duty equipment and passenger vehicles.

With excellent thermal and oxidation stability, this lubricant resists breakdown at elevated temperatures and helps control deposits around seals and bearings.

Key Features & Benefits

• Excellent load-carrying protection: Helps protect gear surfaces against scuffing and wear during demanding service.

• High-temperature performance: Resists thermal breakdown to maintain effective lubrication under heat and load.

• Cleaner critical components: Helps limit deposits around seals and maintain clean bearing surfaces.

• All-season versatility: Multigrade performance can reduce seasonal oil changes where operating temperatures and equipment requirements permit.

• Potential fuel-economy benefits: Helps reduce frictional energy losses for more efficient drivetrain operation.

Recommended Applications

Suitable for qualifying hypoid, spur, bevel, helical, spiral-bevel, and worm gear systems. Designed for use in differentials, final drives, and certain transmissions, transfer cases, and steering mechanisms where SAE 85W-140 and the applicable performance specifications are recommended.
