Mobil Delvac™ 1 Gear Oil LS 75W-90

Fully Synthetic Limited Slip Gear Lubricant

Product Description

Mobil Delvac™ 1 Gear Oil LS 75W-90 is a fully synthetic, limited-slip gear lubricant that been formulated from synthetic base oils and an advanced additive system. It is designed for use in light and heavy duty drivetrains, it provides excellent load-carrying capability in axles and final drives where extreme pressures and shock loading are expected Mobil Delvac 1 Gear Oil LS 75W-90 provides outstanding thermal and oxidation stability, high Viscosity Index (VI), extremely low pour point, and low-temperature fluidity.  Mobil Delvac 1 Gear Oil LS 75W-90 is suitable for service fill use in many limited-slip hypoid differentials.


Features and Benefits

Today’s technology has vastly improved the performance capabilities of heavy duty on and off highway equipment of load, torque, speed, control and reliability through innovative drivetrain designs.  These designs have changed and increased the requirements of drivetrain fluids to deliver higher performance including limited-slip capability, increased productivity, and reduced operating costs.  For heavy duty final drives, friction control, wear protection, thermal stability, shear stability, rust and corrosion protection, and seal protection are features that must be optimally balanced to provide extended gear and seal life, smooth operation, fuel economy and high load high torque capability over a wide range of applications. Mobil Delvac 1 Gear Oil LS 75W-90  is engineered to deliver exceptional performance and low total lubrication-related operating costs in many modern heavy duty final drives requiring limited-slip capability.  The key potential benefits 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.
 Contribution to reduced maintenance costs and long equipment life
Exceptional shear stabilityRetains viscosity and film strength under severe operating conditions to help prevent wear
Enhanced frictional propertiesHelps to improve fuel economy and reduce operating costs
Outstanding low temperature fluidity versus mineral oilsContribution to reduced wear and ease of start up
Good resistance to foamingMaintains film strength for reliable lubrication
Compatible with typical automotive seals and gasketsMinimum leakage and reduced contamination
