Does exceeding the maintenance mileage by a few hundred kilometers have any impact?

[Julia]

Yes. Exceeding the oil change mileage can lead to deteriorated oil fluidity and altered viscosity properties, resulting in insufficient lubrication for the engine, increased wear, and higher fuel consumption. Opting for high-quality oil (such as fully synthetic or imported GT oil) can offer better cost-performance and extend the maintenance interval. Additional information is as follows: 1. Car maintenance considerations: Besides checking the tires, special attention should be paid 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. 2. Other tips: In hotter regions and seasons, it is advisable to choose oil with slightly higher viscosity. Conversely, in colder weather, oil with lower viscosity can be used.

I've been driving for decades. Going a few hundred kilometers over the maintenance interval isn't a big deal, but don't make it a habit. Expired engine oil becomes viscous, reducing lubrication efficiency and potentially causing rough engine operation. Prolonged use increases wear. A clogged filter also affects performance - it might handle short city drives, but poses greater risks on long highway trips. Manufacturers build safety margins into recommended intervals. Exceeding by 500km is manageable, but try not to go too far beyond to avoid skyrocketing repair costs later. I regularly check the dipstick - when the oil turns black, it's time for a change. Your driving style matters too; gentle driving withstands wear better than aggressive acceleration.

I just became a car owner not long ago, and I feel quite nervous about exceeding the maintenance schedule. I heard that aged engine oil can accelerate engine wear, potentially causing abnormal noises or power loss, and there are also safety hazards—breaking down on the road would be troublesome. Not replacing the filter on time allows impurities to enter the system, increasing the likelihood of malfunctions. Exceeding the limit by a few hundred kilometers depends on the situation; new cars might have more leeway, but older cars require extra caution. I make it a habit to set reminders on my phone to avoid forgetting. In summer, high temperatures cause engine oil to degrade faster, so regular maintenance helps protect the lifespan of critical components—don’t save small money only to pay for major repairs later.

I've done the math—going slightly over the maintenance mileage by a few hundred kilometers isn't a big deal and can save some costs. Engine oil has some flexibility in its lifespan; exceeding by 300-500 km for short commutes has minimal impact, but for long-distance or harsh road conditions, extra caution is needed. Filter efficiency declines gradually and won't fail immediately. The key factors are the vehicle's age and oil type—full synthetic oil lasts longer, while semi-synthetic requires more frequent changes. I usually wait until noticeable issues arise before addressing them, but don't make it a habit—excessive delays can lead to engine damage and much higher repair costs. Saving money should still prioritize safety—keep an emergency toolkit in the car just in case.
