Full Synthetic MT-90 75W90 GL-4 Gear Oil, 1 Quart - Pack of 3

MT-90 75W90 GL-4 GEAR OIL

• 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

Product Details

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-mile transmissions
• Compatible with petroleums and other synthetics

OEM Compatability

RED LINE MT-90 HIGH-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.
