Redline MT-90 is popular for owners with manual-transmission cars. Redline MT-90 does not contain the reactive sulfurs found in most GL-5 oils that cause damage, so it's safe for most manual transmission synchros. Other synthetic gear oils are often too slippery for proper synchro engagement, but MT-90 has the appropriate coefficient of friction, so it offers excellent gear and synchro protection, plus balanced slipperiness for easier shifting.
MT-90 is a 75W90 GL-4 gear oil recommended for use in manual transmissions on the track (excluding '06+ Xi manual transmission). MT-90 is a thicker 75W90 version of MTL, and the shear stability and oxidation stability is excellent, so its characteristics change very little with use. 

Not recommended for street use in cold climates.
  • Offers quicker shifts, perfect synchronizer coefficient of friction
  • Eliminates notchy shifting
  • High-performance gear protection and longer synchro life
  • Recommended for GL-1, GL-3, and GL-4 applications as well as where most special synchromesh fluids are specified
