Usually the automobile factory is called the main engine factory, which doesn't produce everything. Toyota is a company with all downstream industries in the OEM, and it can't produce anything by itself. After all, it is impossible for a company to produce all the tens of thousands of parts in a car, plus all kinds of auxiliary supplies. This is bound to find other companies to do OEM. For example, the engine oil in 4S shop is branded, but in fact, the relationship between engine oil and brand is a certified purchase relationship, rather than the engine oil is produced by the brand itself. When changing oil in 4S shop, the so-called original engine oil pushed by 4S shop is OEM engine oil.
Brother Miao took out a bottle of so-called original engine oil from Hyundai 4S shop. Although the labels posted on the back are modern symbols, there are also some modern information. However, the most critical manufacturer information is actually not modern, but OEM by another oil company. In other words, these so-called original engine oils exchanged in 4S shops are basically from other manufacturers, not from the OEM, and it is impossible for the OEM to do everything. On the other hand, these oil manufacturers, that is, these large energy companies, are basically not OEMs, and they don't make cars. These main engine plants buy these oils from them, and then make a certification and put a label on them to sell them as original engine oil.
If you don't go to the 4S shop for maintenance, you can buy engine oil outside. Mobil, Shell, Castrol, Total, Great Wall and Kunlun have nothing to do with the main engine factory. It is produced by these companies specializing in engine oil, except that the main engine factory sells it directly to customers, so there are relatively few price difference middlemen to buy their brands, and the price will be slightly cheaper. Especially when the activities are discounted, the price is still relatively affordable.
Therefore, if the car is out of warranty and you don't want to go to the 4S shop for maintenance, then you must stop obsessing about the so-called original engine oil, especially since it has been kidnapped by the 4S shop. These sales consultants in the 4S shop are very powerful. I don't want to go to the 4S shop for maintenance, so I called you to say that there are various crises under various disadvantages, which makes you feel that it is better to use the original engine oil after buying hundreds of thousands of cars. Actually, Brother Miao tells you that the essence of engine oil is the same, and there is no essential difference between the original engine oil and the engine oil you bought outside.
