Features and Benefits

Today’s technology has vastly improved the performance capabilities of heavy-duty on and off-highway equipment in terms of load, speed, control, and reliability through innovative drivetrain designs. These designs have increased the requirements of drivetrain fluids to deliver higher levels of performance, increase productivity, and reduce operating costs. For heavy-duty transmissions, 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 synchronizer life, smooth shift control, fuel economy, and high load capability over a wide range of applications. Mobil Delvac Synthetic Transmission Fluid Arctic delivers exceptional performance in today’s drivetrains where extremely cold ambient temperatures are encountered. The key benefits include:

FeaturesAdvantages and Potential Benefits
Excellent load carrying, anti-wear, and extreme pressure performanceExtended transmission life and reduced cost of operation
Outstanding protection against deposit formationLonger seal life, extended drain, and service intervals
Maximum protection from corrosion of copper and its alloysProtects and extends the life of synchronizers
Optimized thermal and oxidation protectionCleaner transmissions live longer and run smoother
Excellent shear stability with no viscosity modifiersMaintains effective viscosity and film strength during severe operation
Exceptional low-temperature fluidity and pumpabilityEasier smoother shifting with quicker starts and better lubrication
Extended drain and service interval capabilityLower operating costs and higher productivity
Improved frictional propertiesOptimum clutch-friction retention and slippage control, improved brake performance (anti-chatter), reliability, fuel economy, and lower operating costs


      Recommended by ExxonMobil for use in:

  • Heavy-duty automotive type manual transmissions and gear cases
