Red Line 75W-90NS GL-5 Gear Oil

  • Designed for transmissions and transaxles - helps to slow synchros for easier shifting across a broad temperature range
  • Popular in Ferrari, Porsche and Subaru transaxles
  • Muscle car applications like Ford Top Loader, Borg-Warner T-10, Super T-10 and Muncie transmissions
  • Contains extreme pressure additives like our 75W-90 GL-5 oil, but lacks friction modifiers to balance slipperiness
  • Improved copper corrosion protection to prolong synchro life
  • Helps with lock-up on weak limited-slip differentials-compatible with Red Line Limited Slip Friction Modifier for tuning slippage
  • Also used with clutch-type LSDs in racing for maximum lock up

About Red Line Gear Oil for Differentials

  • Full-synthetic formulas created from polyol ester base stocks, offer excellent lubrication under extreme conditions
  • High viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature change
  • Ester base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gears
  • Superior shear stability and reduced oxidation compared to other synthetics and conventional gear oils
  • Exceed API GL-5 specifications
  • Engineered to provide the highest degree of protection and improvement of differential efficiency for better mileage, longer drain intervals and less wear
