Red Line 57105 75W-140 NS GL-5 Gear Oil - 1 Gallon

Description

Contains extreme pressure additives like our 75W140 GL-5 oil but lacks friction modifiers to balance slipperinessPopular for historic and vintage transmissions like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucksHelps with noisy or rough shifting in troubled A-833 Dodge/Plymouth 4-speed transmissions from 1964 to 1969Option for noisy transmissions when mixed with 75W90NS or MT-90 to bring viscosity level upAlso 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 slippageRecommended for API GL-5 GL-6 MT-1 MIL-L-2105E and SAE J2360Fully-synthetic formulas created from polyol ester base stocks offer excellent lubrication under extreme conditionsHigh viscosity-index (VI) to provide relatively constant viscosity and film thickness with varying temperature changeEster base stocks and friction modifiers provide additional slipperiness to lower operating temperatures by reducing the sliding friction in hypoid gearsSuperior shear stability and reduced oxidation compared to other synthetics and conventional gear oilsExceed API GL-5 specificationsEngineered to provide the highest degree of protection and improvement of differential efficiency for better mileage longer drain intervals and less wearTYPICAL PROPERTIESAPI Service Class GL 5+Viscosity Grade SAE 75W140Vis @ 100 C cSt 26.9Vis @ 40 C cSt 179Viscosity Index 188Pour Point C -45Pour Point F -49Brookfield Viscosity Poise 1200 @ -40 C
