Mobil Delvac 1 Gear Oil 75W-90 

Mobil Delvac™ Synthetic Gear Oil 75W-90

Mobil Delvac™ Synthetic Gear Oil 75W-90 is a  fully synthetic drivetrain lubricant engineered to meet very demanding extended drain and warranty requirements. This product is 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. 
Mobil Delvac Synthetic Gear Oil 75W-90 incorporates synthetic basestock and advanced additives providing significant advantages over conventional gear oils.

The state-of-the-art technology in Mobil Delvac Synthetic Gear Oil 75W-90 delivers excellent performance, helps to protect against thermal degradation and oxidation, contributes to reduced wear and corrosion, improved shear stability and extended service capability.

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:

FeaturesAdvantages and Potential Benefits
Exceptional thermal stability and resistance to high temperature oxidationLong gear and bearing life due to minimal deposits
Long seal life
Outstanding protection against low speed/high torque wear and high speed scoringIncreased load-carrying capability.
Helps to reduce maintenance costs and long equipment life
Exceptional shear stabilityHelps to retain viscosity and film strength under severe operating conditions to prevent wear
Enhanced friction reduction propertiesHas potential for fuel economy and reduce operating costs
Enhanced friction reduction propertiesImproved fuel economy and reduced operating costs
Outstanding low temperature fluidity versus conventional oilsHelps to Reduce wear and ease of start-up
Good resistance to foamingHelps to maintain film strength for reliable lubrication
Compatible with typical automotive seals and gasketsMinimum leakage and reduced contamination
  • Heavy duty non-synchronized manual transmissions, axles and final drives requiring API GL-5 and MT-1 performance
  • On-highway light and heavy duty trucks, busses and vans
