Redline Oil RED57105 75W140NS GL-5 Gear Oil - 1 gal

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 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
