75W90 NS 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
  • Musclecar 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

ABOUT RED LINE GEAR OIL FOR MANUAL TRANSMISSIONS
  • 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
  • MTL, MT-85 & MT-90 are not for use in differentials with hypoid gears
  • Excellent gear and synchro protection, balanced slipperiness for easier shifting in cold climates
  • Excellent for high- and low-mile transmissions
  • Compatible with petroleums and other synthetics

MORE TECHNICAL INFORMATION

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.
