Mobil Delvac 1™ ATF

Advanced technology synthetic automatic transmission fluid

Mobil Delvac 1 ATF is a fully synthetic fluid recommended by Allison Transmission, Inc. and approved against the Allison TES-295 and TES-468 Specifications. 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 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 at sub-zero temperatures.

Mobil Delvac 1 ATF is recommended by ExxonMobil for use in:

  • Modern high-performance trucks
  • Buses
  • Utility vehicles
  • Haulers
  • Vans
  • Other equipment requiring Allison TES-295 and TES-468 or MB-Approval 236.91 performance levels

Features and benefits

  • Enhanced, long-term frictional properties help to improve and extend transmission efficiency for smooth shifting performance and fuel economy potential
  • Exceptional thermal and oxidation stability keep transmissions clean to extend life and performance even under some of the harshest conditions
  • Outstanding film-strength and anti-wear properties help provide significant wear reduction, which can contribute to long transmission life
  • Excellent low-temperature fluidity helps to provide prompt and reliable lubrication at sub-zero ambient temperatures
  • Exceptional shear stability ensures viscosity retention even under some of the severest heavy-duty, high-temperature operating conditions
  • Compatible with mineral ATF fluids and all common seal materials, which can help reduce concern in top-off situations and provide excellent leakage control
