What is the purpose of engine oil inside the engine?
2 Answers
Engine oil serves multiple functions for the engine, including lubrication and friction reduction, auxiliary cooling, sealing to prevent leaks, rust and corrosion prevention, as well as shock absorption and cushioning. Additional information about engine oil is as follows: 1. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties. Additives compensate for and enhance the performance shortcomings of the base oil, imparting new characteristics, making them an essential part of lubricating oil. 2. Only qualified engine oil can reduce wear on engine components and extend their service life. The engine is the heart of a car, containing many metal surfaces that move against each other in friction. These components operate at high speeds, in harsh environments, with working temperatures reaching 400°C to 600°C.
I've always been a car enthusiast, and the engine oil is like the lifeline of the engine. It lubricates all the metal components, such as pistons and crankshafts, reducing friction and wear, and preventing overheating-induced engine seizure. This helps extend the engine's lifespan and avoids costly major repairs. Additionally, engine oil has a cleaning function, carrying away impurities and sludge from combustion to keep the internals clean. It also forms a sealing layer, improving fuel efficiency and reducing power loss. More importantly, engine oil helps cool the engine, preventing overheating shutdowns. Based on my experience, regular oil changes are crucial—it's recommended to check every 5,000 kilometers or every six months; otherwise, the engine might fail prematurely. Choosing the right type of oil is also key, whether conventional or synthetic, to ensure both driving safety and cost-effectiveness.
