Is it necessary to change the engine oil specifically before the vehicle annual inspection?

If the car is only a few years old, there is no need to change the engine oil; regular maintenance according to the normal schedule is sufficient. However, if the car is relatively old, it is advisable to change the engine oil in advance. Below is relevant information about the vehicle annual inspection: Regulations on vehicle annual inspection time: Vehicles within 6 years are exempt from inspection but must obtain an exemption label annually free of charge. Vehicles over 6 years require an annual inspection, while those over 15 years require a semi-annual inspection. Vehicles involved in accidents within 6 years must undergo on-site testing. Vehicles with a manufacturing date over 2 years must be registered. Contents of the vehicle annual inspection: Appearance check, exhaust emission test, chassis inspection, OBD inspection, lighting inspection, and brake inspection. The vehicle annual inspection helps to promptly eliminate potential safety hazards, encourages enhanced vehicle maintenance, and reduces the occurrence of traffic accidents.
From my years of driving experience, there's absolutely no need to change the engine oil specifically before the annual vehicle inspection. The inspection mainly focuses on safety components like brake lights, tire wear, and exhaust emissions - engine oil isn't a direct testing item. Oil changes are part of routine maintenance and should follow the mileage or time intervals recommended in the vehicle manual, such as every 5,000 kilometers or six months. Changing the oil prematurely just for the inspection is a complete waste of money and time. My suggestion is to simply check the oil level and color before the inspection to ensure there's enough and it's not too dirty. While aged oil can affect engine performance and indirectly cause excessive emissions, the inspection itself won't fail you just because you didn't put in fresh oil. The key is maintaining overall good vehicle condition - this way you'll pass the inspection smoothly, saving both money and hassle.
