Full Synthetic 75W90NS GL-5 Gear Oil is made for transmissions & transaxles. It has pressure additives, no friction modifiers, & improved copper corrosion. It is used with clutch-type LSDs & API GL-5, GL-6, MT-1, MIL-L-2105E, & 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 transaxles 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 modifiers can be added or used to customize limited-slip differential operation. 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. The GL-5 75W90NS Gear Oil has the following properties: 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 & 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.
