Red Line MT90 GL4 75W90 Gear Oil

  • Description
  • Additional information


  • Red Line formulates its gear oils specifically for the appropriate coefficient of friction for most manual transmission synchronizers (other’s synthetic gear oils are often too slippery for proper synchro engagement)
  • Rather that offering a one product suits all across GL-4 & GL-5 Red Line offers lubricants to pinpoint nearly every transmission application
  • 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 engine oil viscosity)
  • Popular in Nissan, Mazda, Mitsubishi, VW/Audi, Lotus Elise/Exige, Toyota
  • 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 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
