Why 140 Weight Gear Oil is necessary?

As a car enthusiast, I have learned the importance of using the right type of gear oil in my vehicle’s transmission. While there are various weight options available, I have found that 140 weight gear oil is essential for ensuring optimal performance and longevity of my car’s transmission.

One of the main reasons why 140 weight gear oil is necessary is its high viscosity. This means that it has a thicker consistency compared to lower weight oils. In simple terms, this allows it to provide better protection and lubrication for the gears in the transmission. As gears constantly mesh and rotate at high speeds, they generate a lot of heat and friction. The thick consistency of 140 weight gear oil helps to reduce heat build-up and prevent wear and tear on the gears.

Another important factor is its ability to withstand extreme temperatures. Whether driving in hot summer conditions or cold winter weather, 140 weight gear oil maintains its viscosity and provides consistent protection for the gears. This is particularly important for vehicles that are used for towing or hauling heavy loads, as they put extra strain on the transmission.

Moreover, using 140 weight gear oil also helps to improve fuel efficiency. With proper lubrication and reduced friction, the gears can
