When it comes to car maintenance, many people will think of oil change and mechanical filtration projects. And is car maintenance really that simple? Man Foley Bian Xiao tried his best to finally find an oil worker, and learned a lot from the oil worker. Today I will give you a detailed introduction.

1. Is crude oil really crude oil?

Don't! When you do maintenance in a 4s shop and ask what kind of oil your car uses, the service consultant or maintenance technician will answer: the advanced original oil provided by the manufacturer.

The original engine oil gives people a professional feeling, but actually no automobile manufacturer can produce engine oil, but other well-known lubrication manufacturers produce it. Original oil is just a tool for manufacturers to restrict car owners, but many car owners are lost in the word "original factory".

Is the quality of engine oil used in 2.4s shop good?

No! Generally, 4s shops use low-end oil products that meet the manufacturer's standards, and there will be no problem when they are added to the car. In synthetic engine oil, where the middle and low grade mineral oil is better, the most obvious problems are the weak oil cleaning function and serious sludge, which leads to short maintenance cycle, poor engine working condition and more carbon deposition, thus affecting engine life.

Consultants who want to use a higher level of good oil service often tell you: add money.

3. Can you make good use of oil if you spend too much money?

Not necessarily! Customers are generally not allowed to enter the workshop. The owner can see the workshop in the lounge and the maintenance process of his car from a distance, but this does not affect the tampering of the car by the maintenance master: adding money to buy high-end engine oil, adding low-end oil when actually adding it, not letting go, saving some oil to sell, as for hurting the car but not hurting the car? Who cares? Not his own.

4. Did you change the oil and filter?

Look at the mood! Since the owner can't see the maintenance details of his car, some illegal maintenance technicians can take the opportunity to filter and wipe. If they look ok, they won't change it. The machine filter for changing the paper core is relatively simple, and the owner does not know whether to change it or not.

5, not in the 4s shop, go to a single store and rest assured?

The price of 4s shop is too sharp, so you can rest assured that you don't need the original engine oil if you don't maintain it in 4s shop? It is more difficult. There is more oil in the monomer shop outside. In fact, most single repair shops in China can't make money by changing the oil if they operate normally. Some "smart" owners of individual repair shops have begun to find ways to make profits: a barrel of 4L oil is filled with 150 through regular channels, and some channels only need 120. That's how profits come from.

6. Can the anti-counterfeiting mark of engine oil be anti-counterfeiting?

Not necessarily! "Excellent workmanship" fake oil drums, oil covers and oil boxes are all produced together with the packaging of real oil. The above figures and anti-counterfeiting are available, so you can't find out the authenticity by phone. Usually, this kind of engine oil will not be filled with inferior engine oil, but will only be repackaged with low-grade regular engine oil in vats and turned into high-grade engine oil, or the engine oil of second-line manufacturers will be used as the engine oil of first-line manufacturers to make huge profits, and basically no owner can tell it. According to informed sources, it is not a problem to earn a Land Rover in a small workshop.

7. Fake engine oil is far away from you. Can't you be satisfied?

Where can I buy these fake engine oils? You can find it everywhere. The main producing areas of China engine oil are Tianjin, Zhuhai and Zhejiang, and many fake engine oils also come from there. Some fake engine oil will cause star damage to cars, while others will hurt cars invisibly. There is fake engine oil in a single store, and 4s stores are not necessarily clean. In recent years, due to the poor operating conditions of 4s stores, some 4s stores began to consider engine oil. As far as the current situation is concerned, the quality of engine oil depends entirely on the "conscience" of the operator.

8. I found that I used fake engine oil to protect my rights.

Do car owners need to protect their rights when using fake engine oil? Very difficult

The oil inspection of the first level of rights protection stuck 99% car owners. Only first-tier cities can issue authoritative test reports. The inspection will cost at least 3000 yuan. After the test results come out, we should be prepared for the merchants to shirk their responsibilities. It takes enough effort to quarrel with businessmen. These photos are exhausting to think about.

Perhaps many car owners don't care much about the difference in car maintenance costs or the impact on their cars because of the difference in oil quality, but we can't tolerate cheating.
