Why I Use 75W90 Gl4 Manual Transmission Fluid

As a car enthusiast, I have always been meticulous about maintaining my vehicle. From regular oil changes to tire rotations, I make sure every component of my car is in top condition. One crucial aspect that often gets overlooked is the transmission fluid. After some research and personal experience, I have come to realize the importance of using 75W90 Gl4 manual transmission fluid.

Firstly, let’s understand what this specific type of transmission fluid is. 75W90 refers to its viscosity, which means how thick or thin the fluid is. In simple terms, it affects how well the fluid flows through your transmission. Gl4 stands for gear lubricant grade 4 and is specifically designed for manual transmissions. It contains additives that protect gears and synchronizers from wear and tear, providing better shifting performance.

One of the main reasons why I use 75W90 Gl4 manual transmission fluid is its compatibility with older vehicles. Many older cars require a GL4-rated oil as opposed to newer models that use GL5-rated oils. Using a GL5-rated oil in an older vehicle can cause damage to the synchronizers due to its higher level of sulfur and phosphorus additives.
