Red Line 80W140 GL-5 Gear Oil covers the traditional 80W140 viscosity with a full-synthetic ester formula and the extreme pressure package Red Line uses across its GL-5 line. This listing is the one-quart bottle, the practical size for topping off or for a single-vehicle change when you buy the quarts you need. Sold as a case of 12 one-quart bottles.

Key Features

  • Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360
  • Contains friction modifiers for clutch-type limited slip differentials; for most limited slip units no additional modifier is required
  • Popular in stock car racing differentials and transmissions
  • 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

Differential service where an 80W140 is specified. Red Line lists it as popular in stock car racing differentials and transmissions. Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360.

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.
