Mobil Delvac 1 Gear Oil 75w90 (16 Gal. Keg)

Mobil 122043

Designed to meet the demands of extended drain and warranty requirements in heavy-duty drivetrains, Mobil Delvac 1 Gear Oil 75W-90 is a fully synthetic lubricant incorporating synthetic base stocks and advanced additives that provides significant advantages over conventional gear oils. Mobil Delvac 1 Gear Oil 75W-90 is intended for use in on-highway light- and heavy-duty trucks, buses and vans that require gear lubricants with excellent load-carrying capability and where extreme pressures and shock loading are expected. Other applications of this product include equipment for industries such as mining, quarrying, agriculture and construction.

The advanced technology in Mobil Delvac 1 Gear Oil 75W-90 delivers first-rate performance, helps to guard against thermal degradation and oxidation, contributes to reduced wear and corrosion, and provides exceptional shear stability and extended service capability.

Not suggested for use in API GL-4 applications or manual, automatic or semi-automatic transmissions where engine oil or automatic transmission fluids are recommended.

Product Data Sheet

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 contribute to extended gear and seal life, smooth operation, improved fuel economy potential and high load high torque capability over a wide range of applications. The key benefits of Mobil Delvac 1 Gear Oil 75W-90 include:

Features 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 and high speed scoring Increased load-carrying capability.
Helps to reduce maintenance costs and long equipment life
Exceptional shear stability Helps to retain viscosity and film strength under severe operating conditions to prevent wear
Enhanced friction reduction properties Has potential for fuel economy and reduce operating costs
Outstanding low temperature fluidity versus conventional oils Helps to Reduce wear and ease of start-up
Good resistance to foaming Helps to maintain film strength for reliable lubrication
Compatible with typical automotive seals and gaskets Minimum leakage and reduced contamination
