How long can I drive after the car prompts for an oil change?

You can drive within 50 kilometers after the car prompts for an oil change, and normally you can drive to the 4S shop. Car oil change cycle: Mineral oil is generally changed every six months or about 5,000 kilometers; semi-synthetic oil is changed every 7 to 8 months or about 7,500 kilometers; full synthetic oil is changed every year or about 10,000 kilometers. The role of car oil: It cools the engine by carrying heat back to the oil tank and then dissipating it into the air to help the radiator cool the engine. It also provides sealing to prevent leaks, forming a seal between the piston rings and pistons to reduce gas leakage and prevent external contaminants from entering. It acts as a shock absorber; when the pressure at the engine cylinder port rises sharply, suddenly increasing the load on the pistons, piston chips, connecting rods, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact. Additionally, it lubricates to reduce friction, which is its primary function and basic property. It also prevents rust and corrosion and cleans by adsorbing onto parts' surfaces to prevent contact with water, air, acidic substances, and harmful gases.
Once the car alerts you to change the oil, it's recommended to schedule a replacement as soon as possible and not delay too long. I remember one time when my car gave the alert, I procrastinated for a few days, and the fuel consumption noticeably increased, with the engine sound becoming rougher. Generally, under this alert, you can still safely drive about 300 to 500 kilometers, depending on driving habits: if you mainly cruise on highways with lower engine load, driving around 400 kilometers is acceptable; but if you frequently start and stop in city traffic with higher engine load, it's best not to exceed 300 kilometers. Also, check the oil dipstick—if the oil is black and sticky, it needs to be changed immediately. Delaying can increase engine wear, reduce lifespan, and even lead to costly repairs. In short, once alerted, prioritize scheduling the oil change within a week. Developing good habits ensures your car lasts longer.
