What does regular maintenance at a 4S shop include?

Engine oil, oil filter, spark plugs, brake fluid, power steering fluid, transmission fluid, coolant, tire rotation, timing belt, air filter, cabin air filter, fuel filter, etc. Regular car maintenance mainly involves the replacement and inspection of some wear-prone components, as well as the replacement of various fluids. The intervals for regular car maintenance are as follows: 1. A minor service at 10,000 kilometers includes engine oil and oil filter replacement (oil filter, air filter, and fuel filter). A medium service is at 20,000 kilometers, and a major service is performed every 40,000 kilometers. The 20,000-kilometer service includes the replacement of engine oil, oil filter, air filter, and cabin air filter, along with some routine inspections. 2. Oil filter: Proper installation of the oil filter prevents impurities from mixing into the engine oil during use, avoiding wear on moving parts and blockages in oil passages. 3. Fuel filter: Correct installation of the fuel filter prevents impurities and moisture mixed into the gasoline during storage, transportation, and refueling from causing cylinder wear. To ensure optimal engine performance, the replacement interval for the fuel filter is generally 20,000 kilometers or 1 year.
I've been driving for decades, and routine maintenance at a 4S shop usually includes changing the engine oil and oil filter to keep the engine running smoothly; checking the brake system for pad wear; adjusting tire pressure to the standard value to prevent blowouts; inspecting all lights including front and rear headlights; examining the chassis for loose screws and shock absorber condition; testing the battery voltage to ensure normal starting; sometimes replacing the air filter for fresher breathing. In short, this process covers basic safety needs and prevents common faults. It's recommended that car owners do it on time and not skimp on this expense, as it helps the car age more slowly.
