DISCONTINUED - The recommended replacement product is Mobil Delvac Synthetic Gear Oil 75W-90, 80W-140.

Mobilube SHC 75W-90 and 80W-140 are fully synthetic drivetrain lubricants engineered to meet the most demanding extended drain and OEM warranty requirements. These products are designed for use in heavy duty drivetrains that require gear lubricants with excellent load-carrying capability and where extreme pressures and shock loading are expected The state-of-the-art technology in Mobilube SHC 75W-90 and 80W-140 delivers unequalled performance for low and high temperature applications, including outstanding oxidation stability, wear protection, corrosion resistance, improved shear stability, extended service capability, and excellent fuel economy.

These products meet API MT-1/GL-5 EP gear oil service classifications and are MIL-PRF-2105E quality level. The outstanding performance of these products is confirmed by their approvals for use in axles covered by Eaton Roadranger (E500TM) and ArvinMeritor Extended Warranties of 750,000 miles, with extended oil drains of 500,000 miles. They are also approved by Mack against GO-J Plus (75W-90) and GO-J (80W-140) extended service classifications.

The performance capabilities of today's heavy duty on- and off-highway equipment have vastly improved in terms of load, torque, speed, and reliability through innovative powertrain designs. These designs have increased demands on axle lubricants, requiring them to deliver higher levels of performance. For heavy duty axles, friction control, wear protection, thermal stability, shear stability, rust and corrosion prevention, and seal protection are features that must be balanced to provide extended gear and seal life, smooth operation, improved fuel economy and high load, high torque capability over a wide range of applications. The key benefits of Mobilube SHC 75W-90 and 80W-140 include:

Features	Advantages and Potential Benefits
Exceptional thermal stability and resistance to high temperature oxidation	Extended gear, seal, and bearing life
Outstanding protection against low speed/high torque wear and high speed scoring	Increased load-carrying capability.
Exceptional shear stability	Retains viscosity and film strength under severe operating conditions to prevent wear
Excellent rust, staining, and corrosion protection of copper and its alloys	Reduced wear and longer component life
Enhanced friction reduction properties	Improved fuel economy
Outstanding low temperature fluidity versus conventional oils	Reduced wear and ease of start-up
Good resistance to foaming	Maintains film strength for reliable lubrication
Compatible with typical automotive seals and gaskets	Minimum leakage and reduced contamination
