Product Review

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. Red Line offers lubricants to pinpoint nearly every transmission application. MTL is 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 petroleum and other synthetics. Satisfies the gear oil viscosity requirements of 70W, 75W, 80W, and motor oil viscosities of SAE 30, 10W30, and 5W30. Recommended for GL-1, GL-3, and GL-4 applications as well as where most special synchromesh fluids are specified.
