Product Description

Red Line 58305 75W90 NS GL-5 Gear Oil - 1 Gallon


  • 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
