Why 10 W 40 Motor Oil is Necessary

As a car owner, I have always been particular about taking care of my vehicle and ensuring its longevity. One crucial aspect of maintaining a car’s health is using the right motor oil. After researching and consulting with experts, I have come to understand why 10 W 40 motor oil is necessary for my car.
