75W90NS GL-5 Gear Oil

75W90NS GL-5 Gear Oil

  • Appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
  • Red Line offers lubricants to pinpoint nearly every transmission application
  • 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 and Super T-10, and Muncie transmissions
  • Contains extreme pressure additives like our 75W90 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
  • Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360

Further Info

  • Red Line formulates its gear oils specifically for the appropriate coefficient of friction for most manual transmission synchronizers (other's synthetic gear oils are often too slippery for proper synchro engagement)
  • Rather that offering a one product suits all across GL-4 & GL-5 Red Line offers lubricants to pinpoint nearly every transmission application
  • Fully-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

 

RED LINE 75W90NS HIGH-PERFORMANCE GEAR OIL is a fully-synthetic formula with ester base stocks, designed for use in manual transmissions and transaxles that require GL-5 lubricants. This non-slip formula is formulated for shear stability, less gear noise and consistent viscosity. Extreme pressure (EP) additives allow for use with hypoid gears, but the lack of friction modifiers causes less slipperiness for proper synchronizer operations. Friction modifier can be added or used to customize limited-slip differential operation.
