Why I Always Use 75W-140 Gear Oil With Friction Modifier

As a car enthusiast and mechanic, I have learned the importance of using the right type of gear oil for optimal performance and longevity of my vehicle’s transmission. After experimenting with different types of gear oils, I have found that 75W-140 gear oil with a friction modifier is the best option for my vehicle.

Firstly, the viscosity rating of 75W-140 makes it ideal for both high and low temperatures. This means that during cold weather, the oil will flow smoothly and provide proper lubrication to all parts of the transmission. In hot weather, it will not thin out too much and can still protect against wear and tear. This ensures that my transmission is well-protected in all weather conditions.

Secondly, the addition of a friction modifier in 75W-140 gear oil is crucial for maintaining smooth gear shifts. Friction modifiers are additives that reduce friction between moving parts, which helps to prevent wear on gears and bearings. This is especially important for vehicles with limited-slip differentials as they are more prone to wear without proper lubrication from a friction modifier.
