Mobil commercial-vehicle-lube , Canada

Advanced Technology Synthetic Automatic Transmission Fluid

Product Description

Mobil Delvac 1™ ATF 668 is a fully synthetic transmission fluid recommended by Allison Transmission, Inc. that is approved against the Allison TES 668® Specification, and is backwards compatible for applications recommending Allison TES 295®. 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 668 helps protects against thermal breakdown at high operating temperatures, while still providing outstanding performance at sub-zero temperatures.

Features and Benefits

Mobil Delvac 1™ ATF 668 advanced technology has demonstrated extended drain, long-term friction retention, and low-temperature capability. Further, it helps improve overall transmission durability and cleanliness. Key features and benefits include:

Features	Advantages and Potential Benefits
Enhanced, long-term frictional properties.	Helps improve overall and extends transmission efficiency, smooth shifting performance and fuel economy.
Outstanding film-strength and anti-wear properties.	Helps reduce significant wear and improve long transmission life.
Exceptional thermal and oxidation stability.	Keeps transmissions clean to extend life and performance even under some of the harshest driving conditions.
Excellent low-temperature fluidity.	Provides prompt and reliable lubrication at sub-zero ambient temperatures down to –54º C. Disclaimer: ASTM D97 Pour Point testing data
Exceptional shear stability.	Leads to viscosity retention even under the most severe heavy duty, high temperature operating conditions.
Compatible with mineral ATF fluids.	Reduced concern in top-off situations and excellent seal materials leakage control.
