Redline MTL 75W80 GL-4 Gear Oil
Part #: RED50204
• Safe for brass synchros, as it lacks the reactive sulfurs found in most GL-5 oils that cause damage
• Excellent low-temp flow, improved cold shifting
• For racing differentials under moderate loads
• 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
• 1 Quart
• Sold Individually

PRODUCT DETAILS
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 (others synthetic gear oils are often too slippery for proper synchro engagement)
- Red Line offers lubricants to pinpoint nearly every transmission application
- MT-LV, 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
