"Should I get MT-85 or MT-90?" 

In the Transfer Case - You can go with either MT-85 or MT-90, they're both in spec (other than Gen1s, technically) and the differences between them are very minor in the transfer case. MT-85 may have a slight edge in MPGs and be a better fit for the daily driver/occasional offroader. Whereas MT-90 may be better for the purpose built offroad rig that spends a lot of time in 4 wheel drive because of the slightly greater protection it offers at higher temps. 

In Manual Transmissions - Red Line only recommends MT-85 for Mitsubishi manual transmissions because it results in smoother shifts.

MT-90

  • 75W90 GL-4 gear oil (similar to SAE 5W40/10W40 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 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

Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers these products that ensure proper shifting while providing ultimate wear protection.

  • Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
  • MT-LV, MTL, MT-85 & 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 mileage transmissions
  • Compatible with petroleums and other synthetics
