Car maintenance items include: 1. Replacement of engine oil, oil filter, spark plugs, air filter, cabin air filter, transmission fluid, brake fluid, and coolant; 2. Cleaning of throttle valve and engine carbon deposits; 3. Comprehensive inspection of vehicle components, including checking for oil leaks, aging and wear of rubber parts such as tires and bushings. Vehicle maintenance mainly covers the engine system, transmission system, air conditioning system, cooling system, fuel system, power steering system, and braking system. Car maintenance refers to the regular inspection, cleaning, replenishment, lubrication, adjustment, repair, or replacement of certain parts of the vehicle.

There are quite a few car maintenance items. After driving for over ten years, I've summarized about twenty common ones. First are the minor maintenance items: changing the engine oil and oil filter every 5,000 to 10,000 kilometers; checking tire pressure and wear to ensure no cracks or leaks; replacing the air filter to keep the engine intake clean. Then there are daily monitoring tasks: checking brake pad thickness to prevent brake failure; battery health tests to avoid sudden power loss; inspecting the lighting system for burnt-out bulbs. Major maintenance is more comprehensive: replacing brake fluid to prevent line blockages; changing transmission fluid for smoother shifting; maintaining coolant to prevent engine overheating; installing new spark plugs to ensure ignition efficiency. Don’t forget seasonal maintenance: replacing the cabin air filter every six months to keep the air fresh; checking antifreeze capability in winter. These items vary in frequency and scale, but generally, car owners should perform them two or three times a year. Spending a little money can save you from major repairs and enhance safety.

Regarding the number of car maintenance items, as an ordinary car owner, I find them quite diverse, but there are about a dozen core ones. The most basic is engine oil replacement, required every 7,500 kilometers, which is not costly; regular tire inspection and rotation to balance uneven wear; air filter replacement to ensure smooth engine breathing. Among the inspection items, the brake system is crucial, such as testing the thickness of brake discs and pads; battery condition monitoring to prevent breakdowns; light adjustment including the brightness of headlights and fog lights. Additional items include: air conditioning system maintenance, including filter replacement; drive belt inspection to prevent breakage; electronic control unit diagnostics to ensure proper functioning of electronic devices. Some items depend on the car's condition: older cars require more suspension checks to reduce bumps; new cars need attention to software updates. Overall, there are typically fifteen to twenty common items, and performing them on time can extend the vehicle's lifespan by over five years, offering great cost-effectiveness.

Our family car has quite a few maintenance items, around ten or so. Every time we go to the repair shop, they perform basic oil and filter changes every five to six thousand kilometers; check tire pressure for practicality; test the battery charge for safety. Key maintenance includes the brake pad wear alarm system; air filter anti-clogging; lighting tests including turn signal brightness. Others include coolant top-up to prevent overheating and engine seizure; air conditioning filter replacement every six months for healthy breathing; spark plug inspection for carbon buildup and replacement to improve fuel efficiency. Although there are many items, they are prioritized: minor issues can be noticed and addressed during regular checks to save time and money, while major maintenance is done every two to three years for overall control.
