  • Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota, Mendeola transmissions and Atlas transfer cases for Off Road
  • Satisfies the gear oil viscosity requirements of 75W90, 80W90, 90 and motor oil viscosities of SAE 40, 10W40 and 15W40
  • Recommended for GL-1, GL-3 and GL-4 applications, as well as where most special synchromesh fluids are specified
  • Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
  • 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
  • Offers quicker shifts, perfect synchronizer coefficient of friction
  • High performance gear protection and longer synchro life
  • Eliminates notchy shifting, even when cold

Red Line MT-90 75W90 Gear Oil is a GL-4 lubricant designed for manual transmissions, transaxles, and transfer cases requiring compatible gear oil or special synchromesh fluid. It satisfies viscosity requirements for 75W90, 80W90, and 90 gear oils, as well as SAE 40, 10W40, and 15W40 motor oils.

Key Features & Performance Benefits

  • Synchro protection: Safe for brass synchronizers because it lacks the reactive sulfurs found in many GL-5 oils.
  • Improved shifting: Offers quicker shifts with a coefficient of friction designed for synchronizer operation.
  • Cold-shift performance: Helps eliminate notchy shifting, including when the lubricant is cold.
  • Gear and synchronizer protection: Provides high-performance gear protection and supports longer synchronizer life.
