Redline Oil 75W-90 Ns Gl-5 Gear Oil - 1 Quart

Red Line 75W90 NS GL-5 Gear Oil is a high-performance lubricant specifically designed for transmissions and transaxles, ensuring optimal shifting performance and protection under a broad range of temperatures. Whether you’re driving a high-performance sports car, a muscle car, or a classic vehicle, this fully-synthetic gear oil delivers exceptional gear protection and smooth, precise shifting.

Ideal for High-Performance Applications
Popular in high-end performance vehicles like Ferrari, Porsche, and Subaru transaxles, as well as classic muscle cars such as Ford Top Loader, Muncie transmissions, and Borg-Warner T-10 and Super T-10, Red Line 75W90 NS GL-5 provides superior lubrication and smoother shifting. Its carefully engineered formula is ideal for vehicles with manual transmissions and transaxles that require consistent, reliable performance under diverse conditions.

Improved Shifting and Synchro Protection
This gear oil features extreme pressure additives for superior protection, similar to Red Line's standard 75W90 GL-5 gear oil, but with a unique formulation that lacks friction modifiers to balance slipperiness. This results in improved shifting, with a perfect coefficient of friction for manual transmission synchronizers. It’s designed to slow synchros, making shifting easier across a wide range of temperatures and preventing notchy shifts, especially when cold.

Key Benefits:

• Fully-synthetic formula offers excellent protection and smoother shifting, even under extreme temperatures and heavy loads.
• Safe for use with all synchro materials, helping to extend synchro life and improve performance.
• Non-corrosive formula with enhanced copper corrosion protection prolongs the lifespan of your transmission and components.
• Ideal for clutch-type limited-slip differentials (LSDs) in racing, ensuring maximum lock-up performance. It’s also compatible with Red Line Limited Slip Friction Modifier for customizable slippage.
• Recommended for high-performance vehicles and muscle cars, including Ferrari, Porsche, Subaru, Ford, and other applications requiring API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360 specifications.
• Perfect for reducing lock-up issues in weak LSDs, improving overall differential performance.

Exceptional Gear Protection and Longevity
Engineered to provide superior gear and synchro protection, Red Line 75W90 NS GL-5 Gear Oil excels in high-mileage, low-mileage, and racing transmissions. With its well-balanced slipperiness and high shear stability, this oil is ideal for cold-weather climates, offering smooth shifts and long-lasting protection across a variety of applications. Compatible with petroleum oils and other synthetics, this gear oil ensures maximum performance and efficiency for your vehicle’s drivetrain.

For Manual Transmissions and Transaxles
When used in manual transmissions and transaxles, Red Line 75W90 NS GL-5 ensures precise shifting, reduced wear, and better overall performance, making it the perfect choice for those who demand the best in gear lubrication.
