TRIAX DTF-2 Professional 75W-85 is a full synthetic differential and drive train fluid for a wide range of vehicles, especially many late generation BMW, Audi, Ford, GM, Lexus, Mercedes Benz, Toyota, Dodge RAM, and Nissan. It contains built-in friction modifiers to allow full compatibility with limited slip gear systems (front and rear differentials) without requiring the use of additional friction modifiers. This fluid surpasses the performance of most OEM fluids and top tier brands - emparts by synthetic / ester base oil use, high stability additive system which allows FILL FOR LIFE oil changes in sealed systems, offers better gear engagement, and more wear protection than most other fluids.
