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.
• 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
