The state-of-the-art technology behind Mobilube 1 SHC 75W-90 delivers outstanding viscosity-temperature properties necessary for wide temperature range applications, optimised protection against thermal degradation and oxidation, wear and corrosion, shear stability, extended service capability, and potential fuel economy improvement. Mobilube 1 SHC 75W-90 incorporates the latest technology in synthetic basestocks and advanced additives providing significant advantages over conventional gear oils. This technology also ensures effective lubrication since this product remains fluid without channeling at subzero temperatures. Mobilube 1 SHC 75W-90 meets or exceeds the requirements of the API Service MT-1/GL-4/GL-5 gear oil 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 higher levels of performance, increased productivity, and reduced 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. Mobilube 1 SHC 75W-90 is engineered to deliver exceptional performance and reduce total lube-related operating cost in modern heavy duty drivetrains. The key benefits include: Features Advantages and Potential Benefits Exceptional thermal stability and resistance to high temperature oxidation Long gear and bearing life due to minimal deposits Long seal life Outstanding protection against low speed/high torque wear, spalling, and against high speed scoring Increased load-carrying capability. Reduced maintenance costs and long equipment life Excellent 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 Improved synchroniser performance and long component life Enhanced frictional properties Fuel economy potential and improved shiftability Outstanding low temperature fluidity versus mineral oils Reduced wear and ease of start up--even in arctic conditions Wide multipurpose capability One lubricant for heavy-duty manual transmissions and rear axles Good resistance to foaming Maintains film strength for effective lubrication Compatible with typical automotive seals and gaskets Minimum leakage and reduced contamination
