Phillips 66 Lubricants has announced the addition of two new heavy-duty synthetic transmission lubricants to its Commercial product line—Triton Synthetic MTF and Kendall SHP Synthetic MTF. The new manual transmission fluids are full-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 new Eaton PS-386 specification (supersedes Eaton PS-164 Rev 7).

“Our Triton Synthetic MTF and Kendall SHP Synthetic MTF were developed to provide excellent shear stability and anti-wear properties to protect synchronizers, reduce component wear and promote longer transmission life,” said Tony Negri, Phillips 66 Lubricants’ director of marketing, commercial lubricants. “Both products are ideal for use in newer, higher torque manual transmissions coupled with increased horsepower engines.”
