Generally, the items included in a major vehicle maintenance service are the engine and engine oil, oil filter, air filter, fuel filter, brake fluid, coolant, transmission fluid, power steering fluid, spark plugs, etc. The service typically takes between 2 to 5 hours. Details of a major car maintenance service: A major maintenance service involves replacing the engine oil and oil filter, spark plugs, air filter, cabin air filter, transmission fluid, brake fluid, coolant, cleaning the throttle body and engine carbon deposits, and conducting a comprehensive inspection of the vehicle's components. This includes checking for any leaks, the aging and wear of rubber components such as tires and bushings. The importance of car maintenance: Replacing the fuel filter can filter out impurities and moisture from the fuel, providing clean gasoline to the engine and allowing it to perform at its best. During engine operation, various frictions occur, and the debris generated from these frictions mixes with the engine oil. If the oil is not filtered regularly, it directly affects the engine's lubrication. Factors influencing major maintenance: Different car brands, driving environments, and driving habits can all affect the timing and frequency of a major maintenance service. It is essential for car owners to schedule major maintenance based on the vehicle's condition.

I've been driving for ten years, and every major maintenance service basically includes these items: changing the engine oil and oil filter, which is the most fundamental task to remove impurities and protect the engine; followed by replacing the air filter and fuel filter to help the engine breathe smoothly and burn fuel efficiently; inspecting and replacing the spark plugs is also crucial, as smooth ignition makes the car easier to drive; the braking system must be thoroughly checked, including the brake pads, discs, and fluid—safety is not something to take lightly; tire rotation and alignment should never be skipped, as they extend tire life and reduce wear; updating the coolant and transmission fluid prevents overheating and gear jamming; inspecting and replacing belts prevents breakage; battery voltage testing ensures reliable starts; and replacing the cabin air filter keeps the air fresh. After completing all these, the car runs smoothly and fuel-efficiently, avoiding major repair issues down the line.

I often do my own car maintenance. During major servicing, I usually do these things: first, change the engine oil and oil filter, simple but crucial; replace the air filter if it looks dirty, just a few bucks; regularly update the fuel filter to improve efficiency; install new spark plugs to enhance starting and acceleration; check the brake system to ensure safety and reliability; rotate the tires to reduce wear; replace the coolant and brake fluid to prevent corrosion; change the transmission fluid for smoother shifting; inspect the belt for cracks; test the battery to see if it can start; and service the air conditioning. Spending a little money can save a lot, keeping the car running longer.

The core items of a major vehicle service include: replacing engine oil and filters to maintain engine lubrication; replacing air and fuel filters to enhance filtration; updating spark plugs to improve performance; a comprehensive brake system inspection to ensure safety; tire rotation and alignment to extend lifespan; updating coolant, transmission fluid, and brake fluid to prevent aging; inspecting belts and hoses to prevent failures; battery assessment to ensure startup; and air conditioning maintenance. These measures ensure reliable operation.

Last time I took my car for a major service at the 4S shop, they did a full set: changed the engine oil and oil filter, and the car ran smoothly right after starting; the engine sound became much quieter after cleaning the air filter; the new fuel filter saved gas; new spark plugs made ignition faster; the brake pads were checked and found a bit thin, so they were replaced, making driving feel more secure; the tires were rotated, aligned, and balanced; the coolant was replaced to prevent overheating in summer; the transmission fluid was renewed for smoother gear shifting; the air conditioning filter was cleaned, making the air smell fresh; the battery was tested and found to be fine. It feels like the car has been rejuvenated by a few years after the service, and it visits the repair shop less often.
