Red Line 75W90 NS GL-5 Gear Oil (1 Quart) - 58304

Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E and SAE J2360 applications

This 75W90 GL-5 gear oil is designed for transmission and trans-axles. It is specifically designed to slow synchros for easier shifting across a broad range of temperatures. It is particularly popular in Ferrari, Porsche, and Subaru trans-axles. It also contains extreme pressure additives but lacks friction modifiers to balance slipperiness. In addition, it has improved copper corrosion protection to prolong synchro life.

For differentials, it helps lock up weak limited sleep differentials ad is compatible with Red Line Limited Slip Friction Modifier for tuning slippage. It is also used with clutch type LSD's in racing for maximum lock up.

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
