Can the car still be driven when it displays an oil change reminder?

When the car displays an oil change reminder, it can still be driven. The oil change prompt is a maintenance cycle reminder preset by the manufacturer, simply notifying the owner that the vehicle requires servicing. However, the distance driven after the oil change reminder should not be too long, as prolonged driving without changing the oil may cause damage to the vehicle. Generally, the maintenance cycle for most vehicles is every 5,000 kilometers or six months, though the recommended interval may vary depending on the brand and model. Engine oil, also known as engine lubricant, serves multiple functions such as lubrication, reducing friction, aiding in cooling, sealing against leaks, preventing rust and corrosion, and acting as a shock absorber. It is often referred to as the 'lifeblood' of a car.

I've been repairing cars for over a decade, and every time I encounter an owner with the oil change light on the dashboard, I explain it this way: Engine oil is like the blood of an engine; when it gets dirty, it's time for a change. The light coming on means the computer has detected a drop in oil performance, but the car can still run for a few days—commuting to work is no problem. However, remember to get it changed as soon as possible. I've seen owners stubbornly push it for half a month, only to end up with an engine that sounds like a tractor. Actually, an oil change only takes about half an hour. Spending a few hundred bucks is much better than shelling out thousands for engine repairs. Nowadays, scheduling an appointment at an auto repair shop is very convenient.

Last time my car also had this light on, so I asked my old classmate who works as a mechanic. He said it's a preset maintenance reminder, usually set a bit earlier than the actual limit. I still had about 30% oil life left at that time, so I drove another 200 kilometers before changing it, and nothing went wrong. But don't follow my example, as everyone's driving intensity differs. Those who frequently take long trips should change it as soon as possible. Over time, old oil loses its lubricating properties, doubling wear and tear. It might be fine in the short term, but you don't want it to suddenly break down one day. It's best not to delay for more than a week—find a reliable shop and get fresh oil.

Don't hesitate when that little oil can light comes on! I learned this the hard way - when it first lit up, I thought I'd wait until the weekend to change it, but ended up driving an extra 300km for a business trip. The mechanic said the sludge was almost clumping when I finally changed the oil, and warned I'd have bearing failure in a few more days. Manufacturers designed this light as a safety reminder to tell you the oil life is ending. My advice: get fresh oil within three days of seeing the warning. It's not worth risking major damage to save a few bucks - an oil change costs far less than replacing a ruined engine.
