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. The one-gallon jug covers most single-vehicle services without buying loose quarts. Sold as a case of 4 one-gallon jugs.

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.
