Mobil Delvac 1 Transmission Fluid Arctic  

Mobil Commercial Vehicle Lube, Canada

Supreme Performance Drivetrain Lubricant

Product Description

Mobil Delvac 1 Transmission Fluid Arctic is a supreme performance, synthetic drivetrain lubricant engineered to meet the demanding requirements of major manufacturers of heavy-duty commercial equipment in extremely cold climate applications. It is recommended by ExxonMobil for use in truck and other commercial transmissions where Caterpillar TO-4 and Allison C-4 performance specifications are required.  Mobil Delvac 1 Transmission Fluid Arctic provides outstanding clutch and brake compatibility and friction control along the widest temperature range performance.

The state-of-the-art technology behind Mobil Delvac 1 Transmission Fluid Arctic incorporates the highest performance components formulated to provide optimum protection against wear, corrosion, thermal degradation, and oxidation. The product is very shear stable as it contains no viscosity modifiers. It also provides extended clutch and transmission life and longer component life compared to other types of fluids previously used in these applications.


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 1 Transmission Fluid Arctic delivers exceptional performance in today’s drivetrains where extremely cold ambient temperatures are encountered. The key benefits include:

Features Advantages and Potential Benefits
Excellent load carrying, anti-wear, and extreme pressure performance Extended transmission life and reduced cost of operation
Outstanding protection against deposit formation Longer seal life, extended drain, and service intervals
Maximum protection from corrosion of copper and its alloys Protects and extends the life of synchronizers
Optimized thermal and oxidation protection Cleaner transmissions live longer and run smoother
Excellent shear stability with no viscosity modifiers Maintains effective viscosity and film strength during severe operation
Exceptional low-temperature fluidity and pumpability Easier smoother shifting with quicker starts and better lubrication
Extended drain and service interval capability Lower operating costs and higher productivity
Improved frictional properties Optimum 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
  • On-highway commercial light and heavy-duty trucking, busses, and vans using Allison manual, powershift, or automatic transmissions
  • Off-highway industries including: construction, mining, and agriculture
  • Applications where extended service intervals are required and especially in extremely cold environments
  • Final drives requiring Caterpillar TO-4 fluids
