Why should the car be maintained? Can I bring my own engine oil?

The focus of daily maintenance is maintenance in 4s shop. In terms of automobile maintenance, after-sales maintenance packages will be organized according to the vehicle specifications, such as secondary maintenance after the first maintenance, and engine maintenance products, such as engine cleaning agents and protective agents, will be added on the basis of basic maintenance (replacing engine oil and oil filter). If it is a 20,000-kilometer maintenance node, some maintenance products such as oil circuit, air intake cleaning and throttle cleaning will be added.

Generally speaking, increased maintenance products are the main source of profits. But how effective can these maintenance products be? Can only say that different people have different views! But you have to say that these projects are useless and unreasonable. In a word, skin care products are like healthy people adding some health food occasionally. The advantages outweigh the disadvantages, but the advantages are not obvious!

The daily maintenance of the car, in the eyes of ordinary friends, is nothing more than changing the oil and replacing some filter elements (air and air conditioning), and there is not much cost. In fact, if it is maintained in a 4s shop, this idea is too naive. So, in my opinion, daily maintenance is easy to do, but do you really understand the added maintenance products? Or are you willing to spend more money?

Of course, if you use the engine oil of 4S shop during the warranty period. If you are insured, you can buy your own oil.

During the warranty period, the engine oil of 4S shop must be used. The Three Guarantees Law stipulates that if the engine assembly and gearbox assembly have quality problems during the warranty period, the 4S shop will claim compensation from the manufacturer and replace the assembly and accessories free of charge. If you use your own engine oil during the warranty period, the engine assembly, gearbox assembly and other systems will have quality problems, which is more troublesome. Besides. During the warranty period of the vehicle, the 4S shop after-sales service consultant will persuade the owner to use his own engine oil in accordance with relevant regulations.

If the car is out of warranty, continue to go to the 4S shop for maintenance, and you can bring your own engine oil, but you must ensure that the engine oil you buy is the same model, not fake engine oil. Of course, you can also apply to the 4S shop to buy your own group oil, and buy several barrels at a time (according to the promotion activities of the local 4S shop). Maybe the 4S store will give you a preferential price, go through the formalities and temporarily store it in the service station, and then take it for maintenance.
