Mobilube LS 85W-90 

Mobilube™ LS 85W-90

Mobilube LS 85W-90 is an extra high performance, automotive gear lubricant formulated from select base oils and an advanced additive system specifically for limited-slip differentials. This lubricant is recommended by ExxonMobil for use in applications requiring API GL-5 performance such as heavy duty differentials, axles, and final drives where extreme pressures and shock loading are expected.

Today’s truck and automotive equipment applications place higher performance demands on drive train lubricants. Higher speeds, higher torque, heavier loads, and limited-slip capability require improved formulations to maximise differential life and optimise performance. Longer service intervals place additional demands on the gear lubricant. Mobilube LS 85W-90 gear lubricant is engineered to meet these challenges.   The key benefits include:


Advantages and Potential Benefits

Excellent frictional properties

Effective limited-slip performance

Good thermal stability and resistance to high temperature oxidation

Extended gear and bearing life due to minimal deposits and longer seal life

Protects against low speed/high torque wear and against high speed scoring

Increased load carrying capability reducing operating costs

Excellent rust, staining, and corrosion protection

Reduced wear and maintenance costs

Effective low temperature lubrication

Reduced wear and ease of start-up

Good resistance to foaming

Maintains film strength for reduced wear

Compatible with typical automotive seals and gaskets

Minimum leakage and reduced contamination

Recommended by ExxonMobil for use in:

  • Limited-slip differentials, axles, and final drives requiring API GL-5 level performance
  • Passenger cars, on highway light and heavy duty trucks, busses and vans
  • Off highway industries including: construction, quarrying, and agriculture
  • Other 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
  • Initial fill, top-up, and refill of enclosed automotive type gearing where SAE 85W-90 limited-slip gear lubricants are recommended
  • Not intended for transmissions or transaxles for which engine oil or automatic transmission fluids are recommended
