Red Line Oil 58304 75W-90 NS Gear Oil Synthetic GL-5 - 1 Quart

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)
Red Line offers lubricants to pinpoint nearly every transmission application
MTL, MT-85 and MT-90 are not for use in differentials with hypoid gears

Details:
Sold as 1 Quart
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
Designed for transmissions and trans axles - helps to slow synchros for easier shifting across a broad temperature range
Popular in Ferrari, Porsche and Subaru trans axles
Muscle Car applications like Ford Top Loader, Muncie transmissions, Borg-Warner T-10 and Super T-10
Contains extreme pressure additives like our 75W90 GL-5 oil, but lacks friction modifiers to balance slipperiness
Improved copper corrosion protection to prolong synchro life
Helps with lock-up on weak limited-slip differentials-compatible with Red Line Limited Slip Friction Modifier for tuning slippage
Also used with clutch-type LSDs in racing for maximum lock up
Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360
RED LINE 75W90NS HIGH-PERFORMANCE GEAR OIL is a fully-synthetic formula with ester base stocks, designed for use in manual transmissions and trans axles that require GL-5 lubricants. This non-slip formula is formulated for shear stability, less gear noise and consistent viscosity. Extreme pressure (EP) additives allow for use with hypoid gears, but the lack of friction modifiers causes less slipperiness for proper synchronizer operations. Friction modifier can be added or used to customize limited-slip differential operation.
