Why Gear Oil 75W140 Synthetic is Necessary
As a car enthusiast, I have learned the importance of using the right type of gear oil in my vehicle. One type that I highly recommend is Gear Oil 75W140 Synthetic. This particular gear oil is necessary for a few key reasons.
Firstly, 75W140 refers to the viscosity rating of the oil. Viscosity measures how thick or thin a liquid is, and in this case, 75W140 indicates that this gear oil has a high viscosity. This is crucial for vehicles that undergo heavy load or high stress on their gears, such as towing or hauling heavy loads. The high viscosity of 75W140 synthetic gear oil provides better protection and lubrication for these gears, preventing wear and tear.
Moreover, synthetic gear oils are known for their superior performance compared to conventional oils. They are chemically engineered to have consistent molecules, resulting in better flow and lubrication. In addition, synthetic oils have a higher resistance to breakdown under extreme temperatures and pressures, making them more durable and long-lasting.
Furthermore, Gear Oil 75W140 Synthetic is necessary for vehicles with limited-slip differentials. These differentials require friction modifiers to prevent chatter and ensure smooth operation
