What Does a Major Vehicle Service Include?

Major vehicle maintenance primarily includes the replacement of engine oil and oil filters, air filters, fuel filters, and pollen filters, as well as the servicing and replacement of spark plugs, and related system inspections and maintenance such as transmission fluid. The replacement of engine oil and oil filters is mainly aimed at maintaining the lubrication system. The function of the air filter is to filter the air before it enters the cylinders, removing impurities, dust, sand, and other foreign particles. Spark plugs are consumable parts and should be replaced every 20,000 kilometers. A minor service at 10,000 kilometers involves the engine oil and oil filter, while an intermediate service is performed at 20,000 kilometers. A major service is conducted every 40,000 kilometers.
From my years of driving experience, a full vehicle major maintenance is much more complex. It includes changing the engine oil and oil filter to prevent carbon buildup and wear in the engine. The air filter also needs to be checked, as a dirty one can reduce air intake efficiency. The cabin air filter should be replaced too, otherwise, the air inside the car won't be fresh. The braking system is the top priority—inspect the brake pad thickness and check for any brake fluid leaks, as failure here can be extremely dangerous. Tire wear inspection shouldn't be overlooked either; proper tire pressure saves fuel and ensures safety. Spark plugs need to be tested for ignition performance, as weak ones can increase fuel consumption. Transmission fluid should be changed regularly to prevent drivetrain issues. Coolant levels must also be checked to avoid engine overheating and potential damage. I recommend doing this once a year or every 20,000 kilometers—don’t wait until minor issues turn into major repairs, which cost more and cause unnecessary delays. Regular maintenance keeps your car running smoothly and gives you peace of mind.
