Mobil commercial-vehicle-lube , Canada

Fully Synthetic Heavy Duty Drivetrain Lubricant

Product Description

Mobil Delvac 1™ Axle 75W-85 Performance gear oil is a fully synthetic heavy-duty drivetrain lubricant. Mobil Delvac 1™ Axle 75W-85 Performance oil is specifically formulated to maintain factory efficiency and performance.


Features and Benefits

Today's technology has vastly improved the performance capabilities of heavy-duty on and off-highway equipment load, torque, speed, and control through innovative drivetrain designs. These designs have changed and increased the requirements of lubricants to deliver this higher level of performance, increase productivity, and reduce operating costs. For heavy-duty final drives, friction control, wear protection, thermal stability, shear stability, rust and corrosion prevention, and seal protection are features that must be optimally balanced to contribute to extended gear and seal life, smooth operation, improved fuel economy potential and high load high torque capability over a wide range of applications.



Advantages and Potential Benefits

SAE 75W-85 viscosity grade

Potential for improved fuel economy versus higher viscosity products such as SAE 75W-90 or 80W-90.

Advanced synthetic-based oil and additive technology

Allows up to 3X oil drain intervals compared to mineral oil technology for long-haul use.

Excellent oxidation resistance

Helps prevent oil breakdown at high operating temperatures; promotes cleanliness and minimizes sludge formation.

Outstanding shear stability

Stay-in grade viscosity for improved wear protection and longevity.

Excellent low temperature viscometrics

Effective lubrication at low temperatures; better cold start performance compared to SAE 80W-90 grade oil.



Mobil Delvac 1™ Axle 75W-85 Performance oil is specifically formulated and extensively tested to meet the demanding requirements of Detroit and Daimler axles. Mobil Delvac 1™ Axle 75W-85 Performance oil is the preferred axle oil formulation for both Top Performance and Standard Performance final-drive axles in Freightliner and Western Star trucks.
