Mobilube™ HD Extra
Mobil commercial-vehicle-lube , Canada
Product Description
Mobilube™ HD Extra MG 75W is a high performance commercial gear lubricant formulated from select base oils and an advanced additive system. This lubricant is engineered for performance in heavy-duty commercial manual transmissions, axles, and final drives where severe service with shock loading is expected. It provides an excellent chemical and thermal stability at elevated bulk oil temperatures, good performance at low temperatures, and good rust protection resulting from water contamination and wet conditions. It will provide excellent performance in applications where API GL-6 (Mobilube HD Extra 80W-140) or GL-6/GL-5 (Mobilube Extra MG 75W) lubricants are required. API GL-6 denotes lubricants intended for gears with very high pinion offset where protection from gear scoring in excess of that provided by GL-5 lubricants is required. API GL-6 is no longer active as the original test equipment and procedures are obsolete.
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 optimize operating costs. Longer service intervals place additional demands on the gear lubricant. Mobilube HD Extra gear lubricants are engineered to meet these challenges. The key benefits include:
Features |
Advantages and Potential Benefits |

Excellent rust, staining, and corrosion protection |
Reduced wear and longer component life |
Effective low temperature lubrication |
Reduced wear and ease of start-up |
Wide multipurpose capability |
Reduced number of gear lubricants to simplify inventory and minimize misapplication |
Good resistance to foaming |
Maintains film strength for effective lubrication |
Compatible with typical automotive seals and gaskets |
Minimum leakage and reduced contamination |
Applications
• Heavy-duty manual transmissions, axles, and final drives requiring API GL-6 (inactive) or GL-5 level performance
• On-highway light and heavy-duty trucks, busses, vans, and cars
• Off-highway industries including: construction, mining, quarrying, and agriculture
• Other heavy-duty industrial and automotive applications involving hypoid and other gears operating under conditions where high speed/shock load, high speed/low torque, and/or low speed/high torque conditions prevail
• Mobilube HD Extra gear lubricants are intended for top-off, and refill of enclosed commercial gearing in manual or semiautomatic transmissions where gear lubricants are recommended including drive axles and final drives
• Not recommended for applications requiring API GL-4 Level performance
• Not intended for transmissions for which engine oil or automatic transmission fluids are recommended
