Description
SHELL SPIRAX S2 A 85W-140
Heavy-Duty Extreme Pressure (EP) Automotive Gear Oil (API GL-5) for Differentials, Axles, Final Drives & Heavy-Duty Gear Systems
Product Description
Shell Spirax S2 A 85W-140 is a high-quality mineral-based extreme pressure (EP) gear oil formulated for a wide range of automotive axle and transmission applications operating under heavy-duty conditions.
It uses selected mineral base oils combined with a balanced sulphur-phosphorus EP additive system to provide:
- Excellent anti-wear protection
- Good oxidation stability
- Reliable load-carrying performance
- Protection against shock loading
- Stable lubrication under high-temperature operation
It is particularly suitable for hypoid axles, differentials, final drives, and heavily loaded gear sets.
