Red Line MT-90 75W-90 GL-4 Gear Oil

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

About Red Line Gear Oil for Manual Transmissions

  • Appropriate coefficient of friction for most manual transmission synchronizers (other synthetic gear oils are often too slippery for proper synchro engagement)
  • Red Line offers lubricants to pinpoint nearly every transmission application
  • MTL, MT-85 and MT-90 are not for use in differentials with hypoid gears
  • Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
  • Excellent for high- and low-mile transmissions
  • Compatible with petroleums and other synthetics
