Red Line 75W85 GL-5 Gear Oil is a fuel-efficient differential oil with friction modifier already in the formula. Red Line notes that at 75W it carries roughly a third of the viscosity of a 75W90 at -40 C while delivering comparable wear, film and friction protection. Packaged in the standard one-quart bottle. Sold as a case of 12 one-quart bottles.

Key Features

  • Suits differential, final drive, gear oil and transfer case applications
  • Contains friction modifiers for clutch-type limited slip differentials; for most limited slip units no additional modifier is required
  • Known formerly as LightWeight Gear Oil
  • Popular in many Formula racing transaxles including Hewland LD-200 and FTR sequential
  • Satisfies gear oil viscosity requirements of SAE 75W80, 75W, 80W and 85W, plus SAE 30 and SAE 10W30 motor oil
  • 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

Red Line lists it in many late-model BMW, Dodge, Ford, GM, Jeep, Lexus, Mercedes-Benz, Ram and Toyota applications, covering differential oil, final drive oil, gear oil and transfer case fluid. Also popular in Formula racing transaxles including the Hewland LD-200 and FTR sequential.

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.
