Popular in Nissan Mazda Mitsubishi VW/Audi Lotus Elise/Exige Toyota Mendeola transmissions and Atlas transfer cases for Off Road
Offers quicker shifts perfect synchroniser 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 engine 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
RED LINE MT-90 HIGH-PERFORMANCE GEAR OIL is a fully-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 synchroniser coefficient of friction and offers stronger film strength for better wear protection.
Appropriate coefficient of friction for most manual transmission synchronisers (other's synthetic gear oils are often too slippery for proper synchro engagement)
Red Line offers lubricants to pinpoint nearly every transmission application
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-mile transmissions
Compatible with petroleums and other synthetics
