Red Line MT-85 is the intermediate viscosity in the GL-4 manual transmission range, a 75W85 synthetic that splits the difference between MTL and MT-90. Packaged in the five-gallon pail.

Key Features

  • Recommended for Nissan 350Z and 370Z, and most Maxima, Altima and Sentra, plus Mitsubishi Evolution, Hyundai, Kia and Quaife synchro manual transmissions
  • Used in many NV4500 truck transmission applications including Chevrolet Silverado and Dodge Ram, for Chrysler specification MS-9070
  • Safe for brass synchros, since it lacks the reactive sulfurs found in most GL-5 oils that cause damage
  • Offers quicker shifts and eliminates notchy shifting, even when cold
  • High-performance gear protection and longer synchro life
  • Satisfies gear oil viscosity requirements of 85W and 75W85, and motor oil viscosities of SAE 30 and 5W30
  • Synthetic polyol ester base stocks with a high viscosity index for stable viscosity across temperature
  • Friction coefficient tuned to synchronize gears in most manual transmission synchronizers
  • Safe for brass and fiber synchros
  • Balanced slipperiness for easier shifting, including in cold climates

Applications

Red Line lists MT-85 for Nissan 350Z and 370Z and most Maxima, Altima and Sentra, Mitsubishi Evolution, Hyundai, Kia and Quaife synchro manual transmissions, and for many NV4500 truck transmissions including Chevrolet Silverado and Dodge Ram under Chrysler specification MS-9070.
