Red Line MT-90 Synthetic Gear Oil 75W-90 GL-4 (1 Quart)

Since most GL-5 gear oils for differentials are too slippery for manual transmissions, Red Line offers this MT-90 Synthetic Gear Oil that ensures proper shifting while providing ultimate wear protection. Red Line formulates fully-synthetic oils and chemically-advanced additives using the world’s finest base stocks. Rather than cutting costs by blending in petroleum products, Red Line's motor oils and gear oils use superior ester base stocks that provide extreme stability at high temperatures and superior film strength at lower viscosities where more power can be produced.

• 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

About Red Line Gear Oil For Manual Transmissions:

• Appropriate coefficient of friction for most manual transmission synchronizers (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
