The Importance of Using 85 90W Gear Oil

As a car enthusiast, I have come to learn the importance of using the right gear oil in my vehicle. In particular, the 85 90W gear oil has proven to be essential for proper functioning and longevity of my car’s gears.

Firstly, this type of gear oil is specifically designed for high-performance vehicles and heavy-duty applications. It is able to withstand extreme pressure and high temperatures, ensuring that the gears are well lubricated and protected from wear and tear. This is crucial for ensuring smooth and efficient operation of the gears, especially in vehicles with powerful engines.

Moreover, 85 90W gear oil has a high viscosity index which means it maintains its thickness even at high temperatures.

In addition to its ability to withstand extreme pressure and high temperatures, using 85 90W gear oil also helps improve fuel efficiency. The smooth operation of gears with properly lubricated parts reduces friction and resistance,
