Your car comprises thousands of different moving parts, most of which are metal. Thus, there’s inevitable friction and heat when one metal surface moves against another. The heated part expands in size, and the friction grows, resulting in greater damage to the engine. Replacing the parts isn’t a feasible option all the time as they’re costly. That’s why we need automobile lubricants. They make sure that your car parts function smoothly by reducing the friction between them. As a result, you can prolong the life of your car engine.
