Engine lubrication is the process of applying a lubricant, typically motor oil, to the moving parts of an engine. This oil reduces friction between components, helping to prevent wear and tear. It also helps to cool the engine by carrying heat away from the parts that generate it, ensuring that the engine operates efficiently and lasts longer. In addition to reducing friction and cooling, engine oil also serves to clean the engine by trapping dirt and debris. This keeps the internal components free from harmful buildup, which can lead to engine damage. Regular oil changes are essential to maintain effective lubrication and overall engine health.
