Red Line Racing Oils 75W90 GL-5 Full Synthetic Transmission Gear Oil 1 Gallon Bottle

75W90 GL-5 Gear Oil

• Most popular Red Line gear oil, with thousands of applications for passenger cars, light trucks and racing vehicles
• Contains additional friction modifiers for suitability with clutch-type limited slip differentials - for most LSDs, no additional friction modifiers are required
• This product is not designed for use in most manual transmissions or transaxles in passenger vehicles, since the extreme slipperiness may cause synchronizer mesh issues that lead to shifting problems
• Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, SAE J2360 and Chrysler spec MS-9763
• Suitable replacement for a differential calling for an 80W90 or SAE 90 gear oil

These products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers (except NS) for proper limited-slip operation

• Fully-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
• Ester base stocks and friction modifiers (except NS) provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
• High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
• Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
• Exceed API GL-5 specifications
• Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals, and less wear
