Phillips 66 Lubricants has added two new heavy-duty synthetic transmission lubricants to its commercial product line: Triton Synthetic MTF and Kendall SHP Synthetic MTF.

The manual transmission fluids are fully synthetic, fuel-efficient transmission lubricants designed for use in heavy-duty commercial manual transmissions operating in extreme temperatures and extended service intervals.

Both products are approved for service fill under the Eaton PS-386 specification, which superceded Eaton PS-164 Rev 7.

Both lubricants are designed for “all-climate” performance, with better low-temperature properties and oxidation resistance, as well as thermal stability at high temperatures.

The products also offer improved fuel economy over previous generation SAE 50 manual transmission fluids, good shear stability and anti-wear properties and longer service life of up to 500,000 miles in line-haul applications.
