<p>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)<br />Red Line offers lubricants to pinpoint nearly every transmission application<br /><strong>Details:</strong></p> <ul> <li>Sold as 1 Quart</li> <li>MTL, MT-85 and MT-90 are not for use in differentials with hypoid gears</li> <li>Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates</li> <li>Excellent for high- and low-mile transmissions</li> <li>Compatible with petroleums and other synthetics</li> <li>Compatible with BMW, Honda/Acura, Ford Focus, late-model Mini Cooper, Land Rover/Range Rover LT77S, Dodge and Jeep NV1500, NV3500 , NV3550 and NV5600 truck transmissions</li> <li>Compatible replacement for and improvement over GM Synchromesh (12345349), Auto-Trak II (12378508) and Chrysler spec MS-9224</li> <li>Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage</li> <li>Offers quicker shifts, A perfect synchronizer coefficient of friction</li> <li>Eliminates notchy shifting, even when cold</li> <li>High performance gear protection and longer synchro life</li> </ul> <p>Satisfies the gear oil viscosity requirements of 75W, 80W and motor oil viscosities of SAE 30, 10W30 and 5W30<br />Recommended for GL-1, GL-3 and GL-4 applications as well as where most special synchromesh fluids are specified<br />API Service Class GL-4<br />SAE Viscosity Grade (Motor Oil) 5W30<br />SAE Viscosity Grade (Gear Oil) 75W80<br />Vis at 100 degrees C, CSt 10.4<br />Vis at 40 degrees C, CSt 54.1<br />Viscosity Index 185<br />Pour Point, degrees C neg 50<br />Pour Point, degrees F neg 58<br />Brookfield Viscosity at neg 40 degrees C, Poise 120</p>
