- Designed for transmissions and transaxles - helps to slow synchros for easier shifting across a broad temperature range
- Popular in Ferrari, Porsche and Subaru transaxles
- 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
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)
- 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.
- ABOUT RED LINE GEAR OIL FOR DIFFERENTIALS
- • Full-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
- • High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
- • Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
- • Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
- • Exceed API GL-5 specifications
- • Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals and less wear
