Description
Product Description
Shell Spirax S2 A 85W-140 is a high-quality mineral-based extreme pressure (EP) axle lubricant formulated for heavy-duty automotive axles, hypoid differentials, final drives, and other heavily loaded gear systems operating under severe service conditions. It combines premium mineral base oils with a proven sulphur-phosphorus EP additive package to provide excellent protection against wear, scuffing, rust, corrosion, and oxidation. It is suitable for passenger cars, commercial vehicles, agricultural machinery, construction equipment, and industrial gear applications requiring an API GL-5 SAE 85W-140 lubricant.
Features and Benefits
Excellent Extreme Pressure Protection
The advanced EP additive technology provides outstanding protection against:
- Heavy loads
- Shock loading
- Gear tooth wear
- Scuffing
- Surface fatigue
helping extend axle and differential service life under demanding operating conditions.
High-Quality Mineral Base Oils
Premium mineral base oils provide:
- Stable lubricating film
- Good oxidation resistance
- Reliable viscosity retention
- Effective protection at high operating temperatures
The lubricant maintains an effective oil film between gear teeth under severe loading conditions.
Reliable Oxidation & Thermal Stability
The formulation resists:
- Oxidation
- Oil thickening
- Sludge formation
- Deposit build-up
providing dependable long-term performance and extended lubricant life.
Excellent Corrosion Protection
Protects gears and bearings against:
- Rust
- Moisture
- Corrosion
- Water contamination
helping maintain clean and reliable drivetrain components.
Good Low-Temperature Flow
Despite its high operating viscosity, Shell Spirax S2 A 85W-140 maintains good pumpability and flow during cold starts within its designed operating temperature range.
