I've been driving for decades. During the second , it's usually necessary to change the engine oil and oil filter - these two are the core components to ensure smooth engine operation. The air filter may need replacement depending on the usage environment; if you often drive in dusty areas, it should be changed, though sometimes cleaning it can extend its life. The cabin air filter is recommended for replacement if you frequently use AC during summer, otherwise poor air quality may affect health. Other parts like brake pads, tires, and spark plugs are generally still new during the second maintenance - don't fall for the shop's upsell tactics as they're just trying to make extra profit. Bringing your own parts to a small shop can save you quite a bit, but make sure to choose a reputable one - don't just go for the cheapest option. Also remember to check tire pressure to ensure even wear, especially before long trips when safety is paramount.

I just bought the car two years ago. Last time for the second , I went directly to the 4S shop. They changed the engine oil and oil filter for me, saying these were necessary replacements to keep the car running smoothly. They also replaced the air filter, which cost a bit, but I noticed the manual mentioned the cabin air filter should be changed too, especially since I use the air conditioning daily to drive my kids to school, and dust can easily clog it. Other parts like spark plugs were also suggested for replacement, but I checked online and found it unnecessary for just 10,000 to 20,000 kilometers, purely excessive. During maintenance, don't forget to ask the technician to check the brake fluid and battery—safety first, saving money second. Actually, if you know the basics, buying parts and having someone else replace them is more cost-effective, but I'm too lazy to bother, so I'd rather leave it to the professionals.

In regular car , the second service typically includes changing the engine oil and oil filter as standard. It's crucial to choose the right oil viscosity and avoid using the wrong brand to prevent engine damage. The air filter should be replaced only when it's dirty; otherwise, cleaning it saves money and is eco-friendly. The cabin air filter is recommended to be replaced annually, especially if you frequently drive in urban areas with poor air quality to prevent musty odors. Other parts like spark plugs and fuel filters usually don't need replacement during the second service as they haven't reached the end of their lifespan—don't waste money unnecessarily. Always follow the vehicle manual and avoid being upsold on unnecessary services. Checking tire wear and brake pad thickness is vital; address any abnormalities promptly to reduce accident risks. Spending maintenance costs wisely is the key.

We have one car for commuting to and from work. During the second , only the engine oil and oil filter were replaced. The shop also suggested replacing the cabin air filter, but the price was too high, so I bought one online and replaced it myself, saving a few dozen bucks. The engine air filter didn't look too dirty, so I just cleaned the dust off instead of replacing it. Other parts like the tires and battery are still in good condition, so just checking the tire pressure and fluid levels is enough—replacing them would be a waste of money. It's best to bring the manual to the shop to prevent them from adding unnecessary services. Pay attention to road conditions while driving; areas with lots of gravel can easily damage the filters, so take precautions in advance. Saving money without compromising safety—safe driving is the most worry-free approach.

As an environmentally conscious car owner, for the second , I definitely change the engine oil and oil filter, but opt for low-emission synthetic oil to reduce pollution. The air filter and cabin air filter are replaced only if necessary; if not dirty, they are cleaned instead of replaced to minimize waste generation. Other parts like spark plugs usually don't need replacement during the second maintenance—follow the manufacturer's recommendations to avoid overconsumption. During maintenance, check tire wear to ensure even longevity. I recommend choosing car models with washable filter designs, which are both eco-friendly and convenient, saving resources in the long run. Developing regular maintenance habits not only extends your car's lifespan but also reduces emissions.
