I used Red Line MT-90 75W-90 (GL4) gear oil and it noticeably improved the smoothness of the shift/gear engagement feel and reduced noise as well. In 2017, is a GL5 MT1 rated gear oil acceptable in a thirty year old brass synchro manual transmission? GL5 gear oil is cheap nearly everywhere, GL4 gear oil is mainly from specialty brands and expensive Many gear oils on the market seem to claim to meet both GL-4 and GL-5 as the same time, isn't this impossible though? As GL-4 has too little phosphorous to protect Differentials And GL-5 has too much so it eats away at syncros and makes them slip. GL5 gear oils are recommended for differentials Note this does not mean fluids that say GL4 / GL5 are acceptable. The Subaru transaxle requires a GL5 oil period. Gear oil (or gear lube), also referred to as gear lube, plays an integral part in maintaining manual transmissions, differentials, and gearboxes' performance and longevity. The GL5 lubes are an extreme pressure (EP) variant of gear oil - its additive package is different than the GL4 lube. I just ordered 3 bottles of GL4 gear oil and plan for a gear oil change ASAP. This differentiation primarily hinges on the concentration of extreme-pressure (EP) additives, which bolster gear protection under strain. GL-5 is suitable for hypoid gear service under severe service and shock loads and not for use in a gearbox. They help by providing a sacrificial layer on the gear surfaces to reduce their degradation rate.
