Mobilube™ HD 80W-90
Product Description
Mobilube HD 80W-90 is high performance, heavy duty gear lubricant formulated from high performance base oils and an advanced additive system. The lubricant is engineered for automotive applications including heavy duty axles and final drives where extreme pressures and shock loading are expected. It is recommended by ExxonMobil for applications where API GL-5 service is required.
Features and Benefits
Today’s heavy equipment applications place higher performance demands on drive train lubricants. Higher speeds, higher torque, and heavier loads require improved formulations to maximise equipment life and optimise operating costs. Longer service intervals place additional demands on the gear lubricant requiring effective basestock and additive systems. Mobilube HD 80W-90 is engineered to meet these challenges. The key benefits include:
| Features | Advantages and Potential Benefits |
| Exceptional thermal stability and resistance to high temperature oxidation | Extended gear and bearing life due to minimal deposits
Longer seal life |
| Outstanding protection against low speed/high torque wear and against high speed scoring | Increased load carrying capability
Reduced maintenance costs and longer equipment life |
| Excellent rust and corrosion protection | Reduced wear and longer component life |
| Effective low temperature lubrication | Improved startability |
| Compatible with typical automotive seals and gaskets | Minimum leakage and reduced contamination |
Applications
Recommended by ExxonMobil for use in:
– Heavy duty axles and final drives requiring API GL-5 level performance.
– Passenger cars, on highway light and heavy duty trucks and commercial vehicles.
– Off highway industries including: construction, mining, quarrying, and agriculture.
– Other heavy duty industrial and automotive applications involving hypoid gears operating under conditions where high speed/shock load, high speed/low torque, and/or low speed/high torque prevail.
