Lubricating oil is a special type of oil used to reduce friction between moving parts in machines and engines. It helps keep components running smoothly, preventing wear and tear. This oil can be found in various applications, from cars to industrial machinery, ensuring that everything operates efficiently and lasts longer. In addition to reducing friction, lubricating oil also helps to cool down parts that generate heat during operation. It can carry away dirt and debris, keeping the machinery clean. Different types of lubricating oils, such as synthetic oil and mineral oil, are available, each designed for specific uses and conditions.
