Red Line 75W90 GL-5 Gear Oil is the company's most versatile differential oil and the default choice for most hypoid applications. It is suitable for 80W90 and 90W GL-5 service. This is the one-quart bottle, sized for a single fill or for keeping a spare on the shelf. Sold as a case of 12 one-quart bottles.

Key Features

  • Synthetic base stock with polyol esters for wear protection under extreme pressure
  • Contains friction modifiers, enough for most limited-slip units
  • Superior oxidation and shear resistance for consistent viscosity in service
  • Natural multigrade properties without unstable thickeners

Applications

Differentials in passenger cars, light trucks and racing applications. Recommended for API GL-5, GL-6 and MT-1, MIL-L-2105E, SAE J2360 and Chrysler MS-9763, and a suitable replacement where 80W90 or SAE 90 is specified.

Red Line does not recommend this product for most manual transmissions or transaxles with synchronizers. The extreme slipperiness can cause synchronizer mesh issues and shifting problems. Use an MT-series GL-4 gear oil in those applications.
