The engine is the "heart" of the car, and the oil is known as the "blood" of the engine, which can be said to be quite important. But now the fake oil on the market is flooded, and the various tricks made by the counterfeit gang make the driver pick a dizzy.
Fake oil incidents are frequently in the news, but why have they been banned so far? What are the dangers of using fake oils? Let's talk about the fake oil today, I hope that everyone can effectively avoid the threat of fake oil and use the car with peace of mind.
Huge industrial chain
Fake oil has always been a hot topic, and the huge profits and loopholes in the channel make it impossible to stop the counterfeiting of oil. Previously, CCTV's "Skynet" column reported this phenomenon, unveiling the industrial chain behind the fake oil for the audience.
In this case, whether it is from the supply of crude oil, the supply of packaging materials to the final production and production, the entire chain is quite perfect. And the daily shipment volume is also very large, and the network sales chain is almost all over the country.
At present, the fake oil on the market is mainly derived from low-quality barrel mineral oil, which is disguised as high quality by repacking. Under normal circumstances, waste engine oil can be used to refine building release agents, waterproof coatings and other purposes, but there are cases where these black-hearted merchants use various methods through sedimentation filtration to carry out secondary sales.
A total of 14 major criminal suspects were arrested in this case, 18 counterfeiting dens and warehouses were destroyed, more than 5,000 bottles were counterfeited, more than 270,000 empty bottles were counterfeited, 27 tons of raw material oil used for counterfeiting, and the sales amount reached 2.2 billion yuan!
And last year alone was exposed as many as 21 cases of fake oil, this is only one of them, can imagine, how many should not be exposed?
High profits make fake oil counterfeit without interruption
It is understood that the factory price of a certain batch of seized counterfeit and inferior motor oil products is only 55 yuan / bottle, and the reference retail price is 398 yuan / bottle, which is nearly 7 times lower than the market price. A bottle of fake machine oil directly earns a net profit of 100 yuan, and some even 350 yuan.
The reason why fake engine oil is rampant in China is because its profits are extremely high, and many small processing workshops have been spawned under the temptation of money, accompanied by various high-tech means to make it more difficult for law enforcement departments to crack down on counterfeiting.
But in fact, the topic of fake oil has always maintained a very high degree of heat, "real bottle fake oil", "real and fake mixed to sell", "fake two-dimensional code fake 400 phone" and other counterfeiting methods, has long been no secret. However, with the improvement of the counterfeiting technology of the gangs, these seem to them to be easy to crack.
Secondly, fake oil also belongs to the oil, the use of fake oil will not say that immediately let the engine problem, under normal circumstances, this mineral oil to let the vehicle travel thousands of kilometers is no problem. This also means that the owner cannot find the problem of fake oil in time, which undoubtedly increases the difficulty of finding the time to solve the case.
And while the use of fake oils doesn't cause immediate problems, the damage of fake oils to the engine is well known.
Light overhaul, heavy scrap
1, carbon deposition increases
An important role of the oil is to clean up the carbon deposit, which is cleaned up in the running engine, returned to the fuel tank, and cleaned up when the oil is changed next time.
However, the cleaning performance of the fake oil is poor, and the accumulated carbon will cause damage to the engine by accumulating carbon over time, and the carbon deposition will be attached to the surface of the internal parts of the engine, affecting its normal operation, generating noise and increasing fuel consumption. Even carbon deposits will spontaneously combust, produce knocks, weaken the engine power, and cause damage to the engine connecting rod crankshaft.
2. Poor lubrication force, easy to cause mechanical failure
In addition to cleaning up carbon deposits, another big role of the engine is lubrication, the reason why we will change the oil is to help the engine play a lubricating role.
The lubrication effect of the fake oil is very poor, so that the engine lubrication is not in place, and the running-in is not smooth, which will cause the engine to shake and even aggravate the wear of the engine. Accumulated time can also cause damage to the engine, and in severe cases, it may also cause cylinder pulling.
3. Aggravate metal corrosion
Good quality oil can be well attached to the surface of the parts, effectively reduce the adverse effects of external pollution on the parts, and the fake oil will not be completely fitted to the surface, the thinner oil film can not play an isolating role, over time, the metal parts will appear oxidation, and even will be corroded.
The old driver said that if the situation is relatively light, it can be repaired, but if the situation is very serious, it needs to be scrapped.
Having said all that, is there any way to discern?
True and false oil identification method
1. Check the oil packaging
After determining the oil to buy, the first place to observe is the outer packaging to see if there is a sealing cap for disposable oil, whether there is tin foil at the gap, and the tin foil of the high-grade oil has a raised trademark. If the oil drum is worn a lot and the edges of the pattern code are not clear, it is even more unlikely to be true.
2, smell the smell to see the color
Genuine motor oil is light and transparent, no impurities, suspended solids or sediments, no irritating odor. On the contrary, if the color is uneven, the flow is not uniform, and there is a pungent odor after opening the oil, it is often a fake or spoiled oil.
3. Skin contact
Good oil drips a little on the belly of the finger, the oil that slowly walks along your fingerprint is genuine, and the fake oil is thin and slippery. In addition, good quality oil has a clear feeling of burning hands, while inferior oil is applied a little on the back of the hand, and there is a clear feeling of coldness.
In reality, there are many ways to distinguish between true and false oil, which is also a clichéd topic, and it is good to strengthen the learning of relevant knowledge in this regard, but fake oil also has all the characteristics of oil, even if the fake oil of waste oil is purified for the second time, it is obtained by using separation purification and deodorization equipment.
Therefore, we must try to avoid contact with all the "three noes" products, folk proverbs: greedy and cheap to eat big losses, do not buy through online small shops, do not go to the repair shop that do not understand, do not believe that they swear that I am the fidelity of this oil, in fact, they can not identify.
Editor's Note
Nowadays, the counterfeiting methods of engine oil are getting higher and higher, and the methods provided on the Internet are difficult to distinguish between good and bad, and the way we can avoid buying fake oil is to choose a regular 4s store or a regular purchase channel. Problems can also be traced back to the source, giving themselves more protection for their safety. (Text/Wang Manyu)
