Triton® Synthetic MTF

# LBPH830036

Phillips 66® Triton Synthetic MTF (Manual Transmission Fluid) is a full-synthetic, fuel-efficient transmission lubricant designed for use in heavy-duty commercial manual transmissions operating in extreme temperatures and/or extended service intervals. It combines outstanding low-temperature properties with outstanding oxidation resistance and thermal stability at high temperatures to provide excellent all-climate, year-round performance. It provides improved fuel efficiency of up to 1.5% compared with previous-generation SAE 50 manual transmission fluids.

Features & Benefits

• Extended drain, all-season performance

• Outstanding oxidation resistance and thermal stability to minimize sludge and varnish formation

• Improved low-temperature properties for easier shifting in cold weather

• Improved fuel efficiency

• High shear stability

• High load-carrying capacity

• Protects against component wear and gear micropitting

• Protects against rust and corrosion

• Good foam resistance

• Excellent seal compatibility


• Heavy-duty manual and semi-automatic transmissions in commercial vehicles where the OEM specifies a non-EP SAE 40 or SAE 50 API MT-1 transmission fluid, an API GL-1 SAE 90 gear oil, or an SAE 40 or SAE 50 heavy-duty engine oil
