Does exceeding the maintenance mileage by a few hundred kilometers have any impact?
2 Answers
Yes. Exceeding the oil change mileage can lead to reduced oil fluidity and changes in viscosity properties, resulting in insufficient lubrication for the engine, increased wear, and higher fuel consumption. Choosing high-quality oil (such as full synthetic or imported GT oil) can offer better cost-performance and extend the maintenance interval. Additional details are as follows: Car maintenance considerations: Besides checking the tires, it's essential to pay attention to the oil viscosity during seasonal maintenance. It is recommended that car owners consider seasonal changes when selecting engine oil, as oil viscosity varies with temperature—higher in winter and lower in summer. Other tips: In hotter regions or seasons, opt for oil with slightly higher viscosity. Conversely, during colder weather, use oil with lower viscosity.
I went over the recommended service interval by about 500 kilometers last time, and to be honest, I was quite worried. I asked the mechanic at the repair shop, and he said occasionally exceeding by a few hundred kilometers isn't a big deal, especially with newer cars. The key is to check the engine oil condition—if it hasn't turned black or thickened, it's still okay. But don't make it a habit. If you exceed by over 1,000 kilometers, the lubrication effectiveness of the oil decreases, and engine wear increases. Since then, I've set an early reminder on my phone so I won't forget. Actually, the most important thing about regular maintenance is keeping all the car's components working in harmony. Exceeding the interval by too much can affect the vehicle's lifespan.
