How Often Should Engine Oil Be Changed for a Car?
2 Answers
Under normal circumstances, the engine oil for a car should be 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 to change the oil regularly during daily use to reduce engine wear and extend its lifespan. Engine oil is often referred to as the lifeblood of the engine, as the engine cannot function properly without it. Inside the engine, oil not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. When the engine is running, the oil forms a protective film on the surfaces of various components, preventing direct contact and friction between them.
I've driven several cars before and feel that oil changes shouldn't be treated as one-size-fits-all. Generally, mineral oil needs replacement every 5,000 km or six months, while full synthetic oil can last up to 10,000 km or a year. But it also depends on your driving habits—if you frequently encounter city traffic jams with the engine running at low speeds, the oil's lifespan may shorten to 7,000-8,000 km. Last time during maintenance, the technician mentioned that modern cars now come with electronic reminder systems that intelligently determine oil change intervals based on actual driving conditions, which is quite convenient. Also, don't just rely on mileage—regular self-checks are crucial: if the oil appears black and sticky or has a pungent smell, you should change it immediately regardless of usage duration. Pay extra attention during winter's low temperatures as aged oil loses fluidity, making cold starts particularly damaging to the engine. In short, timely oil changes are vital for engine protection.
