Red Line MT-85 75W85 GL-4 Synthetic Gear Oil is a premium manual transmission lubricant engineered to improve shift quality and protect internal components. Formulated to provide the ideal coefficient of friction for synchronizers, this synthetic fluid eliminates "notchy" shifting even in cold temperatures. Unlike many standard gear oils, MT-85 is completely safe for brass synchronizers because it lacks the reactive sulfurs found in GL-5 oils that cause corrosion and premature wear.

This 75W85 formula satisfies the viscosity requirements for 85W gear oils as well as SAE 30 and 5W30 motor oils often specified for manual gearboxes. It is a direct solution for transmissions requiring Chrysler MS-9070 specifications or those used in heavy-duty NV4500 applications.

  • Enhanced Shift Performance: Provides quicker, smoother engagement and consistent synchronizer friction.
  • Component Protection: High-performance synthetic base provides superior gear protection and extended synchro life.
  • Broad Compatibility: Recommended for GL-1, GL-3, and GL-4 applications, including special synchromesh fluid specifications.
  • Brass-Safe Chemistry: Non-corrosive to yellow metals, ensuring the longevity of synchronizer rings.
  • Common Fitments: Ideal for Nissan 350Z, 370Z, Maxima, Altima, Sentra; Mitsubishi Evolution; select Hyundai and Kia models; and Quaife manual transmissions.
