Red Line Full Synthetic 80W140 GL-5 Gear Oil is an old-school viscosity that still out-protects the competition. GL-5 products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers for proper limited-slip operation. Full Synthetic 80W140 GL-5 Gear Oil is recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360. It 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 manual transmission or transaxles with synchronizers, as its slipperiness may lead to shifting problems. Also, it is popular in stock car racing differentials and transmissions.

• Full synthetic
• High viscosity-index
• Relatively constant viscosity & film thickness with varying temp change
• Ester base stocks
• Friction modifiers
• Superior shear stability
• Less oxidation
• Exceeds API GL-5 specs
• Longer drain intervals
