Synthetic ATF

D SATFMobil Delvac™ Synthetic ATF
Advanced technology synthetic automatic transmission fluid

Mobil Delvac Synthetic 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 Synthetic ATF protects against thermal breakdown at high operating temperatures, while still providing outstanding performance at sub-zero temperatures.

Mobil Delvac Synthetic 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.
