Why Change Engine Oil?
2 Answers
Reasons for changing engine oil: Engine oil is as vital to an engine as blood is to a heart. It contains various additives that effectively protect the engine's crucial moving parts, ensuring normal operation. Functions of engine oil: 1. Lubrication: The primary function of engine oil is lubrication. It forms an oil film on the metal surfaces of the engine, reducing wear and tear. 2. Cleaning: It breaks down sludge and deposits generated during engine operation, keeping the engine internals clean. 3. Rust prevention: It neutralizes acidic substances produced during engine use and forms a rust and corrosion-resistant layer, preventing oxidation and rusting of metal components. 4. Sealing: It seals the gaps between pistons and cylinders, ensuring complete fuel combustion and improving fuel efficiency. 5. Cooling: It dissipates high temperatures generated by engine wear, protecting various engine components.
Engine oil is like the blood of the engine, responsible for lubricating the constantly moving parts. Over time, the oil accumulates various metal debris, dust, and becomes thinner and dirtier. If not changed, it's like making the engine run on dirty water, causing rapid wear. Moreover, engine oil has another important task—carrying away the engine's heat. Dirty oil significantly reduces cooling efficiency, making overheating more likely in summer. I've seen many car owners try to save money by skipping a few maintenance sessions, only to end up spending seven or eight thousand on major engine repairs—far more costly than regular oil changes. Typically, you should check and replace the oil every 8,000 to 10,000 kilometers, but always refer to your car's manual for specifics. Remember, when changing the oil, also check the oil filter—skipping this small component means the oil change is practically wasted.
