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 maximize equipment life and minimize operating costs. Longer service intervals place additional demands on the gear lubricant requiring effective basestock and additive systems. Mobilube HD 80W-140 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 Longer component life |
| Effective low temperature lubrication | Reduced wear and ease of start-up |
| Wide application capability | Reduced number of gear lubricants required |
| Compatible with typical commercial 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
- On-highway 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
