Redline MTL 75W80 GL-4 Gear Oil
- Popular for BMW, Honda and Acura, Ford Focus, late-model Mini Cooper, Land Rover/Range Rover LT77S, Dodge & Jeep NV1500, NV3500 , NV3550 and NV5600 truck transmissions
- Popular replacement for and improvement over GM Synchromesh® (#12345349) and Auto-Trak II® (#12378508) and Chrysler spec MS-9224
- Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
- Offers quicker shifts, perfect synchronizer coefficient of friction
- Eliminates notchy shifting, even when cold
- High performance gear protection and longer synchro life
- Satisfies the gear oil viscosity requirements of 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
- 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
