Red Line 75W140NS GL-5 Gear Oil (57104)

Red Line



NS means non-slip, for transaxles that need hypoid-protection and smooth shifting. Red Line 75W140NS GL-5 Gear Oil can be used with various applications and is recommended for use with Mitsubishi manual transmissions including the Evolution 4-9, Evo X, DSM and 3000GT/Stealth models. Great for both 5-speed and 6-speed manual transmissions to help prevent the gears from scuffing in high torque situations. Fluids ship to the lower 48 United States only.

Red Line 75W140NS GL-5 Gear Oil:

These products contain the extreme pressure additives necessary for ultimate protection road cars and racing vehicles, as well as friction modifiers for proper limited-slip operation
  • 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
  • Contains extreme pressure additives like the Red Line 75W140 GL-5 oil, but lacks friction modifiers to balance slipperiness
  • Popular for historic and vintage transmissions, like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks
  • Helps with noisy or rough shifting in troubled A-833 Dodge/Plymouth 4-speed transmissions from 1964 to 1969
  • Option for noisy transmissions when mixed with 75W90NS or MT-90 to bring viscosity level up
  • Also used in clutch-type limited slip differentials in racing for maximum lock up-some users add Limited Slip Friction Modifier in small doses to customize slippage
