ExxonMobil and Allison Transmission have teamed up to release a new synthetic transmission fluid that meets the demanding requirements of the TES-295 certification.
Branded Mobil Delvac Synthetic ATF,
the new lubricant will be available in drums, pails and gallon jugs, and will replace the current severe-application ATF sold under the same name. The TES-295 specification is one of the industry's most stringent specifications for automatic transmission fluids.
The new Mobil Delvac Synthetic ATF meets or exceeds these specifications and is ideal for use in trucks, buses, utility vehicles, haulers and vans.
Yeong Kwon, Commercial Vehicle Lubricants' product offer adviser, ExxonMobil Lubricants & Specialties, said, "For this new product, we worked in close cooperation with Allison's engineers to test and evaluate the new Mobil Delvac Synthetic ATF so that it will deliver the exceptional performance required for extended drain intervals, as well as extended product coverages."
Allison certified the new Mobil Delvac Synthetic ATF as a TES-295 fluid based on the exceptional results of a number of different performance tests, including the fluid's resistance to oxidation, viscosity stability, antifoaming capabilities, extreme temperature performance and antiwear properties. This performance was demonstrated in the laboratory, as well as during extended field tests.
Taking advantage of ExxonMobil's and Allison's extensive distribution and sales networks, the new Mobil Delvac Synthetic ATF will be available globally for the first time.
"Allison designs its transmissions for the most severe on or off-highway conditions, so any fluid that we certify as TES- 295 has to deliver first-rate performance under these extreme applications," says Lou Gilbert, Allison Transmission's North American marketing manager. "ExxonMobil manufactures industry proven products, so we were happy to work with the company to provide the new Mobil Delvac Synthetic ATF."
