REDLINE 75W140 NS GL-5 Gear Oil, US Quart (946ml)
Contains extreme pressure additives like a 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. Can be used as an 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.
