RED LINE MT-85 HIGH-PERFORMANCE GEAR OIL is a full-synthetic ester-based lubricant designed for use in manual transmissions and front-wheel-drive transaxles. This shear-stable formula resists breakdown for extended periods and offers more consistent viscosity in warm and cold temperatures for less gear noise and improved shifting. This fluid is less slippery for improved synchronizer coefficient of friction and offers stronger film strength for better wear protection. It is recommended for Nissan 350Z and 370Z (also most Maxima, Altima, & Sentra), Mitsubishi Evolution, Hyundai, Kia and Quaife synchro manual trans applications, as well as many NV4500 truck transmission applications like Chevy Silverado and Dodge Ram (Chrysler spec MS-9070). It lacks the reactive sulfurs found in most GL-5 oils that cause damage (which makes it safe for brass synchros), offers quicker shifts, has a perfect synchronizer coefficient of friction, eliminates notchy shifting (even when cold), and has high performance gear protection and longer synchro life. It is recommended for GL-1, GL-3, and GL-4 applications, as well as where most special synchromesh fluids are specified. Also, it satisfies the gear oil viscosity requirements of 75W, 80W, 85W, and motor oil viscosities of SAE 30 and 5W30

• 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 petroleums & other synthetics
