Allison recommends TES 668® approved oils to extend drain intervals and improve transmission performance and durability in all operating environments.

Allison TES 668® approved oils are recommended for use in Allison 1000 Series™, 2000 Series™, 3000 Series™, 4000 Series™ and H 40/50 EP™ on-highway products.

Petro-Canada DuraDriveTM HD Synthetic 668

The toughest and most demanding test for any oil is to meet the factory fill standards demanded by the world’s leading OEMs.

Allison Transmission, Inc, the leading global supplier of commercial automatic transmissions, has chosen Petro-Canada Lubricants as the sole global factory fill supplier of the new TES 668™ specification fluid.

Petro-Canada Lubricants’ DuraDrive HD Synthetic 668 has met and exceeded the TES 668™ specification with full compatibility with TES 295®.

Petro-Canada DuraDriveTM HD Synthetic 668

Now Allison Transmission customers will experience the durability, performance and equipment protection provided by Petro-Canada Lubricants’ automatic transmission fluids.

Allison created the new TES 668™ specification in order to provide its customers with a fluid capable of performing more functions, such as providing better friction performance and improved anti-wear protection for their transmissions.

DuraDrive HD Synthetic 668 is the first fluid to complete Allison’s rigorous validation program, receive license approval and earn Allison’s global factory fill program.

DuraDrive HD Synthetic 668 will be backward compatible with all Allison heavy-duty and medium-duty transmissions that currently require an approved TES 295® automatic transmission fluid.
