Mobil Commercial Vehicle Lube, Finland

Multi-Purpose Drivetrain Lubricant

Product Description

Mobilube™ S 80W-90 is an extra high performance drivetrain lubricant engineered to provide excellent  lubrication for state-of-the-art, heavy duty manual transmission components used in on-highway commercial vehicles and cars. Potential benefits include excellent shifting performance, good low temperature fluidity, and high temperature viscosity retention.  Mobilube S 80W-90 provides API GL-4/5 level performance.


Features and Benefits

Today's technology has vastly improved the performance capabilities of on-highway vehicles in terms of load, speed, and control through inno-drivetrain designs. These designs have increased the requirements of components and lubricants to deliver a higher level of performance. For heavy-duty applications, friction control, wear reduction, thermal stability, shear stability, rust and corrosion inhibition, and seal protection are features that must be optimally balanced to contribute to long gear and synchroniser life, smooth shift control, fuel economy, and high load capability over a wide range of applications. Mobilube S 80W-90 delivers outstanding performance in current as well as older units. The key benefits include:

Features Advantages and Potential Benefits
Outstanding load carrying, anti-wear, and extreme pressure performance Helps to promote long transmission life.
Excellent prevention of deposits and lacquer formation Helps to promote long seal life, extended drain, and service intervals
Excellent protection from corrosion of copper and its alloys Helps to promote long life of synchronisers and smoother shifting performance
Effective thermal and oxidation resistance at high operating temperatures Helps to promote reduced wear and long component life
Excellent shear stability Maintains effective viscosity and film strength during severe operation
Good low-temperature fluidity Easier, smoother shifting and quicker starts



      Recommended by ExxonMobil for use in:

  • Cars, on highway light and heavy duty trucks, busses, and vans
