Red Line Oil 75W140NS

- Contains extreme pressure additives like our 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
- Recommended for API GL-5, GL-6, MT-1, MIL-L-2105E, and SAE J2360
