Why 85 90W Gear Oil is Necessary

As a car enthusiast, I have learned the importance of using the right type of gear oil for my vehicle. One type that I have found to be essential is the 85 90W gear oil. This specialized lubricant is specifically designed to meet the needs of high-performance vehicles that require heavy-duty gear protection.

First and foremost, the viscosity rating of gear oil plays a crucial role in its effectiveness. The “85” in 85 90W indicates its viscosity at lower temperatures, while the “90” represents its viscosity at higher temperatures. This means that it maintains its consistency and flowability in extreme weather conditions, making it suitable for both hot summers and cold winters.

Moreover, high-performance vehicles often have powerful engines that produce a significant amount of heat. This heat can cause the gears to wear out quickly if not properly lubricated. The 85 90W gear oil has additives that provide superior thermal stability, ensuring that it can withstand high temperatures without breaking down or thinning out.

Additionally, this gear oil has excellent extreme pressure (EP) properties. EP additives are crucial in protecting gears from damage due to high pressures and shock loads. These additives form a protective film on
