Full Synthetic MTL 70W80 GL-4 Gear Oil (16 gal) has Vis@100°C= 10.4 CSt, Vis@40°C= 50.8 CSt, Viscosity Index= 201, SAE Viscosity Grade= 75W80 (gear oil ) & 5W30 (motor oil), gear & synchro protection, & balanced slipperiness.

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. Red Line offers lubricants to pinpoint nearly every transmission application. This Full Synthetic MTL 70W80 GL-4 Gear Oil is compatible with petroleum's and other synthetics. MTL, MT-85, & MT-90 are not for use in differentials with hypoid gears. This product is popular for BMW, Honda/Acura, Ford Focus, late-model Mini Cooper, Land Rover/Range Rover LT77S, Dodge & Jeep NV1500, NV3500 , NV3550, and NV5600 truck transmissions. It is also a popular replacement for and improvement over GM Synchromesh (#12345349), Auto-Trak II (#12378508), and Chrysler spec MS-9224. It is safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage. It offers quicker shifts and is a perfect synchronizer coefficient of friction. It also eliminates notchy shifting (even when cold); has high performance gear protection; longer synchro life; and satisfies the gear oil viscosity requirements of 75W, 80W, and motor oil viscosities of SAE 30, 10W30 and 5W30; It is recommended for GL-1, GL-3 and GL-4 applications as well as where most special synchromesh fluids are specified.

• Apt coefficient of friction for most manual transmission synchronizers
• Gear & synchro protection
• Balanced slipperiness
• Easier shifting in cold climates
• Great for high- & low-mile transmissions
• Works with petroleum's & other synthetics
