Mobil 1 LS 75W-90 Synthetic Gear Lube - MIL-PRF-2105E

Mobil Delvac Synthetic Gear Oil 75W-90 is a synthetic drivetrain lubricants engineered to meet the most demanding extended drain and warranty requirements. This product is designed for use in heavy-duty drivetrains that require gear lubricants with relatively high viscosity and excellent load-carrying capability and where extreme pressures and shock loading are expected. Mobil Delvac Synthetic Gear Oil 75W-90 incorporates the latest technology in synthetic basestocks and advanced additives providing significant advantages over mineral gear oils.

The state-of-the-art technology in Mobil Delvac Synthetic Gear Oil 75W-90 delivers unsurpassed performance for low and high temperature application, protection against thermal degradation and oxidation, reduced wear and corrosion, improved shear stability, extended service capability, and excellent fuel economy. This product meets or exceed the requirements of API service MT-1/GL-5 EP gear oil service classification and is recommended by ExxonMobil for use in applications requiring the MIL-PRF-2105E specification.

The outstanding performance of this product is confirmed by its approval for final drives covered by Eaton Roadranger (E500) 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.

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 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 Mobil Delvac Synthetic Gear Oil 75W-90 include:

Features Advantages and Potential Benefits Exceptional thermal stability and resistance to high temperature oxidation Extended gear and bearing life due to minimal deposits Longer seal life Outstanding protection against low speed/high torque wear and high speed scoring Increased load-carrying capability. Reduced maintenance costs and longer equipment life 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 and reduced operating costs Outstanding low temperature fluidity versus mineral 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
