Why 80W 90 Gl5 Gear Oil is necessary?

I have been an avid car enthusiast for years, and one thing I have learned is the importance of using the right gear oil in my vehicle. After doing some research and consulting with mechanics, I found that 80W 90 Gl5 gear oil is necessary for a variety of reasons.

Firstly, this type of gear oil has a high viscosity, meaning it can withstand high temperatures and heavy loads without breaking down. This is crucial for the gears in a vehicle’s transmission, as they constantly undergo extreme pressures and friction. Using a lower viscosity oil can lead to premature wear and tear on these gears, causing them to fail sooner than expected.

Moreover, 80W 90 Gl5 gear oil contains additives that provide extra protection against wear and tear. These additives help to reduce friction and prevent metal-to-metal contact between gears, prolonging their lifespan. They also aid in keeping the gears clean by preventing the formation of sludge and deposits.

Additionally, this type of gear oil is specifically designed for use in differentials and hypoid gears, which have a unique design compared to other types of gears. The high-performance additives in 80W 90 Gl5 gear oil are
