Car first primarily involves changing the engine oil and oil filter. Introduction to car first maintenance items: 1. While changing the engine oil and oil filter, a comprehensive vehicle inspection will be conducted, including checking all lights, fluid levels, functionality of the electrical systems, tire inspection and pressure adjustment, condition of chassis components, and checking for oil leaks and proper operation of the engine and transmission. 2. Professional diagnostic equipment will be used to perform a computer scan of the entire vehicle, and the maintenance reminder will be reset. 3. A small number of vehicles may also require replacement of transmission fluid, differential oil, and other fluids during the first maintenance.

I just took my new car for its first service last week and found that they mainly replaced two things: engine oil and the oil filter. During the break-in period, metal shavings can accumulate in the engine, so fresh oil is needed to flush them out, and the oil filter is there to catch these impurities. The service advisor at the dealership also checked some free items like the chassis bolts, tire pressure, and brake pad thickness, and ran a computer diagnostic on the engine data stream. A special reminder: always bring your manual for the first service. Some shops might try to upsell you on throttle body cleaning or fuel additives, which are completely unnecessary and a waste of money for the first service.

As someone who has owned three cars, the first is actually quite simple. The key is to thoroughly drain the old engine oil mixed with metal particles. It's recommended to use the manufacturer-certified oil grade—I've seen cases where people damaged their engines by using cheap off-brand oil. The oil filter must be replaced simultaneously, which is like putting a mask on the engine. Don't overthink other items—just follow what the maintenance manual specifies. My last first maintenance only took 30 minutes to complete, and the 4S shop even performed free checks on the coolant level and brake fluid moisture content, since manufacturers need to collect new car data anyway.

Last time I accompanied my friend for the first , I found the key was to change the engine oil and oil filter. During the first 3,000 kilometers, the engine friction pairs are breaking in, and the oil will be mixed with aluminum chips and copper powder. Not changing it in time will accelerate wear. The mechanic said that now the first maintenance has been upgraded to full synthetic oil, which provides better protection than mineral oil. They will also check the tire pressure reset, upgrade the ECU program, and tighten the chassis bolts, all of which are free. Be especially careful not to be tricked by the after-sales service into paying for additional items, as the first maintenance is subsidized by the manufacturer.
