Red Line 75W140NS GL-5
£26.95
Red Line 75W140 NS GL-5 Gear Oil is a popular transmission oil for historic and vintage transmissions, like Mid-1930s to early-1950s synchro-equipped gearboxes in cars and trucks
It contains extreme pressure additives like Red Line 75W140 GL-5 oil, but lacks friction modifiers to balance slipperiness
One popular option for this oil, to resolve noisy transmissions, is to mix 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 customise slippage

Red Line makes gear oils for specific applications, not one type to satisfy most fairly well.
Their GL-5 differential lubricants contain friction modifiers and reducers to lubricate limited-slip clutches properly and reduce friction of the ring and pinion. Non Slip or "NS" gear oils are designed for transmission use where synchronizers need the proper friction to synchronize gear shifts.
The “MT” series is designed for synchronized gearshift applications where lower sulfur levels are desired.
All formulas have a high viscosity index to deliver relatively constant viscosity with temperature change. Synthetic polyol ester base stocks deliver excellent lubrication under extreme conditions, superior shear and oxidation stability, as well as natural multigrade properties, eliminating the need for unstable thickeners.
Red Line gear and transmission oils are recommended for passenger car, commercial and racing applications.
