It uses synthetic base stocks and a sulfur‑phosphorus extreme‑pressure additive package to protect gears from wear, high torque, and thermal breakdown. The SAE 50W viscosity helps maintain a strong fluid film under high loads, reduces foaming and corrosion, and supports smooth, quiet transmission operation over extended drain intervals. It is intended for transmissions that call for a non-EP, SAE 50W fluid meeting specifications like Eaton PS-386, Meritor O-81, and ZF Freedomline.
