Supreme performance transmission lubricant

Mobil Delvac 1 Transmission Fluid 50 is a full synthetic, manual transmission lubricant engineered to meet some of the most demanding extended drain and original equipment manufacturer (OEM) warranty requirements.

Mobil Delvac 1 Transmission Fluid 50 is recommended for year-round lubrication of manual transmissions in light- to severe-duty on- and off-highway equipment operating in a wide range of environments.

Designed to provide maximum protection and extended operating life to heavy-duty transmissions, Mobil Delvac 1 Transmission Fluid 50 provides significant advantages over conventional sulfur-phosphorus gear oils, including outstanding high-temperature performance, oxidation stability, wear protection and corrosion control.

Outstanding performance is confirmed by approval against the Mack TO-A Plus 500,000 mile extended service classification for Mack T300 series manual transmissions. Mobil Delvac 1 Transmission Fluid 50 meets or exceeds the requirements of the API service MT-1 classification and is recommended by ExxonMobil for use in transmissions and gear cases where API Service GL-1 through GL-4 (non-EP) gear protection is required.
