What is "motor oil"?
Motor oil is a special kind of oil used to lubricate the moving parts inside a vehicle's engine. It helps reduce friction between the engine's parts, preventing them from wearing out quickly. Motor oil also helps clean the engine by carrying away dirt and debris, and it helps cool the engine by absorbing heat. There are different types of motor oil, such as conventional, synthetic, and blended, each designed for different kinds of engines and driving conditions. Regularly changing the motor oil is important for keeping the engine running smoothly and efficiently.
