As we all know, car maintenance is related to driving safety and car service life. Car owners need to check and replace car parts regularly in order to drive with more peace of mind. But in fact, car maintenance can also be divided into major maintenance and minor maintenance. For novices, it is also very confusing what the difference between minor maintenance and major maintenance is, and it is often impossible to judge when and what kind of maintenance to do. Today, let’s follow in the footsteps of SAIC Volkswagen’s after-sales service and take a look at the difference between minor maintenance and major maintenance of cars!
What is the difference between minor maintenance and major maintenance? Let’s look at minor maintenance first
Generally speaking, minor maintenance refers to the routine maintenance of the vehicle within a certain mileage specified by manufacturing in order to ensure the performance of the vehicle. Minor maintenance items include changing the oil and changing the oil filter element. Engine oil can play a lubricating role when the engine is running, forming an oil film on the surface of the two parts, effectively reducing the wear of the parts and prolonging the service life of each part. In addition, the engine oil has the functions of cooling, cleaning, sealing and leakage prevention, rust and corrosion prevention, shock absorption and buffering, etc. As the name implies, the oil filter element is a device that filters the oil. The impurities and particles produced during the cycle of the oil will be filtered out by the machine filter, which can prevent the impurities and particles from circulating in the engine and aggravate wear.
The time between minor maintenance depends on the effective time or mileage of engine oil and filter. Engine oil is also divided into many types, such as ordinary mineral oil, semi-synthetic engine oil and fully synthetic engine oil. Minor maintenance is generally performed regularly according to the recommendations of the automobile manufacturer. For example, SAIC Volkswagen official website suggests that the first maintenance time is one year after purchasing or after driving 5,000 kilometers, and then the oil and filter can be replaced every 5,000 kilometers.
What is the difference between minor maintenance and major maintenance? Let’s look at the big maintenance
Generally speaking, major maintenance alternates with minor maintenance. The difference between minor maintenance and major maintenance is also reflected in the items. Besides the oil filter replacement items included in minor maintenance, major maintenance also includes air filter element, gasoline filter element and other items. The air filter element is a device that filters out particles and dust in the air, because the operation of the engine requires sufficient air, and the existence of the air filter element can improve the purity of the air, ensure sufficient combustion, and avoid dust and impurities from causing wear and tear on the piston and cylinder. The gasoline filter element can filter out impurities in gasoline, provide clean oil to the engine, ensure stable engine operation and improve driving safety.
As for the cycle of major maintenance, it varies according to the car brand. For example, SAIC Volkswagen recommends that car owners replace the air filter element every 20,000 kilometers or 2 years after sales.
SAIC Volkswagen’s after-sales service has popularized the difference between minor maintenance and major maintenance for everyone. After reading it, novices believe that they have basically understood the relevant knowledge of car maintenance. In addition to the above maintenance items, the car maintenance staff will also provide other inspections during each maintenance, such as cleaning and maintenance of engine-related systems, tire inspection, etc., to ensure driving safety. If you are a SAIC Volkswagen owner, you can also go to the SAIC Volkswagen 4 S shop for maintenance regularly according to the car maintenance manual, which is more worry-free and labor-saving.
