Mobil Delvac 1 ATF  

Mobil Delvac 1™ ATF

Mobil Delvac 1™ ATF is a fully synthetic fluid recommended by Allison Transmission, Inc. approved against the Allison TES-295 Specification. The fluid is designed to meet the demanding requirements of modern heavy duty automatic transmissions. The synthetic base oil composition enables excellent performance even in some of the harshest of operating conditions. It offers outstanding gear shifting and power transfer performance. Versus conventional ATF fluids, the inherently high viscosity index and stability of Mobil Delvac 1 ATF protects against thermal breakdown at high operating temperatures, while still providing outstanding performance atsub-zero temperatures.

Mobil Delvac 1 ATF advanced technology has demonstrated extended drain, long-term friction retention, and low-temperature capability. Further, it improves overall transmission durability and cleanliness. Key features and benefits include:

FeaturesAdvantages and Potential Benefits
Enhanced, long-term frictional properties.Helps improve overall and extends transmission efficiency, smooth shifting performance and fuel economy.
Exceptional thermal and oxidation stability.Keeps transmissions clean to extend life and performance even under some of the harshest driving conditions.
Outstanding film-strength and antiwear properties.Significant wear reduction and long transmission life.
Excellent low-temperature fluidity.Provides prompt and reliable lubrication at sub-zero ambient temperatures down to –54º C.
Exceptional shear stability.Leads to viscosity retention even under the severest heavy duty, high temperature operating conditions.
Compatible with mineral ATF fluids.Reduced concern in top-off situations and excellent seal materials leakage control.


Mobil Delvac 1 ATF is recommended by ExxonMobil for use in modern high performance trucks, buses, utility vehicles, haulers, vans and other equipment requiring Allison TES-295 or MB-Approval 236.91 performance levels.
