How often should the engine oil of a sedan be changed?

[MacAnastasia]

The engine oil of a sedan is generally changed every 6 months or 8,000 kilometers. However, the specific interval depends on driving conditions, driving habits, and the type of oil used. It is recommended that car owners regularly change the engine oil during normal use to reduce engine wear and prolong the engine's lifespan. Engine oil is often referred to as the 'blood' of the engine, as the engine cannot function properly without it. Inside the engine, oil not only lubricates but also cleans, seals, buffers, prevents rust, and dissipates heat. Over time, the performance of engine oil degrades, so it needs to be changed regularly. Failure to change the oil for extended periods can accelerate engine wear.
