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). 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. Red Line MT-85 Hight Performance Gear Oil is a full-synthetic ester-based lubricant designed for use in manual transmissions and front-wheel-drive transaxles. This shear-stable formula resists breakdown for extended periods and offers more consistent viscosity in warm and cold temperatures for less gear noise and improved shifting. This fluid is less slippery for improved synchronizer coefficient of friction and offers stronger film strength for better wear protection. Red Line offers lubricants to pinpoint nearly every transmission application Details: Sold as 1 Quart Recommended for Nissan 350Z and 370Z (also most Maxima, Altima andSentra), Mitsubishi Evolution, Hyundai, Kia and Quaife synchro manual trans applications Many NV4500 truck transmission applications like Chevy Silverado and Dodge Ram, for Chrysler spec MS-9070 Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage Offers quicker shifts, perfect synchronizer coefficient of friction Eliminates notchy shifting, even when cold 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 Satisfies the gear oil viscosity requirements of 75W, 80W, 85W and motor oil viscosities of SAE 30 and 5W30 Suitable replacement for: Castrol BOT 0063 Castrol BOT 402 Castrol Syntorq LT Chrysler/Dodge 4637579 Chrysler/Dodge 4874459 Chrysler/Dodge 4874464 Chrysler/Dodge MS-9070 Fiat/Alfa 9.5550-MZ1 Fuchs-Titan Pro SRG 75 GM 1940182 GM 10953477 GM 12346190 GM 88862472 GM 88862473 GM 93165290 GM 93740319 Hyundai/Kia 04300-00110 Hyundai/Kia 04300-00140 Hyundai/Kia 08950-00020-A Hyundai/Kia 08950-00020-B Kia API GL-4 SAE 75W-85, fill for-life MB 235.4 MB 235.5 MB 001 989 14 03 MB MAN 341 Typ Z4 Mitsubishi 3717610 Mitsubishi DiaQueen Transmission Oil MZ313376 Nissan MTF HQ Multi 999MP-MTF00P Nissan KE916-99931 Nissan KE916-99932R Nissan KE916-99942R Nissan KE916-99962 Nissan KLD26-75802 Nissan MT-XZ Opel B 040 2071 VW/Audi G 052 190 VW/Audi G 055 190 API Service Class GL 4 SAE Viscosity Grade (Motor Oil) 5W30 SAE Viscosity Grade (Gear Oil) 75W85 Vis at 100 degrees C 12.0 Vis at 40 degrees C 64.3 Viscosity Index 186 Pour Point, degrees C neg 48 Pour Point, degrees F neg 54 Brookfield Viscosity at neg 40 degrees C, Poise 160
