Red Line MT-85 75W85 GL-4 1 Gallon - Case of 4

Red Line MT-85 75W85 GL-4 Gear Oil - 1 Gallon (Case of 4) | High-Performance Synthetic Manual Transmission Fluid

Upgrade your manual transmission with Red Line MT-85 75W85 GL-4 gear oil. This fully-synthetic fluid provides superior protection for synchros and gears, eliminates notchy shifting, and is safe for brass components. Ideal for a wide range of vehicles, including Nissan, Hyundai, and Kia.

Red Line MT-85 75W85 GL-4 is a top-of-the-line, fully-synthetic gear oil meticulously engineered for manual transmissions and front-wheel-drive transaxles. It is a premium lubricant designed to outperform conventional oils, providing exceptional protection and performance. Unlike many GL-5 gear oils, MT-85 is specifically formulated with a balanced slipperiness that ensures a perfect coefficient of friction for proper synchronizer engagement, which is crucial for smooth and precise shifts. Its shear-stable formula resists breakdown under high stress and extreme temperatures, maintaining a consistent viscosity and film strength. This reduces friction, wear, and gear noise, ultimately extending the life of your transmission components. This case of four 1-gallon containers is the perfect solution for workshops, enthusiasts, or anyone needing to service multiple vehicles.

Best Uses

1. Manual Transmissions: Specifically designed for a wide range of manual transmissions that require a GL-4 fluid.
2. Performance Vehicles: Ideal for performance cars and sports coupes like the Nissan 350Z/370Z, Mitsubishi Evolution, and others.
3. Daily Drivers: Enhances shifting and protects components in everyday vehicles, making for a smoother and more enjoyable driving experience.
4. High-Stress Applications: Provides superior protection for vehicles in racing, heavy towing, or other high-load conditions.
5. Specific Vehicle Applications: Recommended for a number of vehicles including Nissan (350Z, 370Z, Maxima, Altima, Sentra), Mitsubishi Evolution, Hyundai, Kia, and NV4500 truck transmissions (Chevy Silverado, Dodge Ram).
6. Classic Cars: Safe and effective for older vehicles that specify a GL-1, GL-3, or GL-4 gear oil.

 Key Features

1. Full-Synthetic, Ester-Based Formula: Utilizes high-quality synthetic base stocks for superior performance and longevity compared to conventional and even other synthetic gear oils.
2. GL-4 Specific Formulation: Designed to meet the requirements of GL-4 manual transmissions, providing the correct friction coefficient for proper synchronizer operation.
3. Safe for Brass Synchros: Does not contain the reactive sulfurs found in many GL-5 oils that can corrode and damage soft yellow metals like brass.
4. Exceptional Thermal Stability: Resists breakdown under extreme temperatures, ensuring consistent viscosity and protection in both high-heat and cold-weather conditions.
5. Shear-Stable Formula: Maintains its viscosity and film strength under high shearing forces, providing consistent lubrication and protection over extended drain intervals.

 Key Benefits

1. Smoother, Quicker Shifts: The balanced friction properties lead to a more effective synchronizer engagement, eliminating "notchy" shifting and making gear changes quicker and more precise.
2. Extended Transmission Life: Superior wear protection reduces friction on gears and synchronizers, significantly extending the lifespan of critical transmission components.
3. Improved Cold-Weather Shifting: Excellent low-temperature fluidity allows for easier and smoother shifting during cold starts and warm-up periods.
4. Reduced Gear Noise: The strong film strength and consistent viscosity help to dampen noise, resulting in a quieter operation.
5. Versatile Application: Recommended for a variety of viscosity grades and specifications (75W85, 85W, 75W, SAE 30, and 5W30), making it a versatile choice for many vehicles.
