How much sugar should I put in the engine?

Recently, the news that "the owner of a luxury brand in Hubei put a lot of sugar into his car engine, which caused the owner to repair the car at his own expense" has aroused the concern and worry of many netizens. 3. During the sensitive period of15, the engine "sugaring" shady broke out again, and Bian Xiao thought it was suspected of speculation. In fact, there was news about adding sugar to engines a few years ago. Even if it is true, it can only be regarded as a rare accident. The villain conspired to frame him, and then the media reported that fermentation caused an uproar. Let's talk about the trouble caused by adding sugar to the engine.

■ engine "sweetening" reappearance

During March 15, some social media constantly exposed the shady maintenance of 4S shops to satisfy readers' concern about the automobile aftermarket. It is rumored that the engine is the heart of a car, and the oil as a lubricant is the blood flowing in the "heart". Adding sugar to the oil will make the car suffer from "chronic heart disease". Therefore, engine failure can be delayed. In this way, after the owner opens a 4S shop, the engine failure will gradually appear, and the owner will return to the 4S shop for maintenance and earn maintenance fees. Sounds like a shady business, but there are still many doubts about this phenomenon.

■ The problem is coming. Adding sugar is man-made damage and does not meet the manufacturer's warranty conditions.

The warranty period of vehicle engine given by the manufacturer ranges from three years /65438+ 10,000 km to six years/15000 km. During this period, when the vehicle reaches the required maintenance, the manufacturer will guarantee any quality problems. However, adding sugar is a malicious act, so the person responsible for the crime must be found, which is also the main reason for the quarrel between 4S stores and car owners in news reports.

■ There are many doubts, so it is impossible for 4S to make a profit.

Doubt 1: How do you know it's sugar? Really dare to taste?

According to related news, after the fault was found, the maintenance workers identified the white sugar in the oil through tasting. When I heard these words, Bian Xiao admired this brother's courage. Seeing that black engine oil contains granular objects, who would think of using the tongue to identify it?

Doubt 2: How did you join?

To add sugar to the engine, you must first turn on the engine, which requires the car key. The owner will only give the key to others when doing maintenance. Usually every corner of the 4S shop, especially the maintenance workshop, will be monitored, and it is difficult to have an empty operation room.

Doubt 3: There is residue in the engine compartment.

According to related news, there is sugar in the engine compartment, which is characterized as evidence of adding sugar to the 4S shop maintenance workshop. Imagine that the repairman who does this kind of black-handed work must be a skilled worker. The oil filler is large enough, even if there is overflow, the repairman will clean it up without leaving any traces.

Doubt 4: How to avoid being discovered by the owner?

Oil circulation is a very sophisticated and complicated system. When the engine is cold, the oil is stored in the oil pan and circulates continuously with the engine running. Sugar will damage the oil pump and pipeline of lubrication system in a short time. Sugar blocks the oil system, which will inevitably lead to insufficient oil pressure, and the oil lamp alarm will make the owner realize that he has been tampered with.

Except sugar, water, salt and sand?

The effect of adding salt is similar to that of adding sugar, except that the melting point of salt is higher and the particles are smaller, and both of them will not be completely dissolved in engine oil, which will cause engine oil blockage; If water is added, the lubrication effect will be directly reduced, and the oil system will be mixed with water, resulting in permanent damage to the engine cylinder explosion; The main component of sand is silicon dioxide. We know that this is a very hard material, which will cause abnormal internal friction, directly cause engine cylinder pulling, and even make your engine directly scrapped.

In short, no matter what items are added, the oil will deteriorate. Lubricating oil is the lubricant between mechanical friction, and the addition of impurities will inevitably interfere with the normal oil circuit circulation, resulting in blockage, physical wear and other failures.

■ If sugar is added, the engine needs to be completely disassembled and overhauled.

If the above faults really occur, the engine needs to be overhauled, all oil circuits need to be cleaned and inspected, and blocked oil pumps, oil pipes and other parts need to be replaced. Engine overhaul is a huge and tedious project, which requires high man-hour cost. Prices range from several thousand yuan to tens of thousands of yuan. Coupled with the cost of materials, the overall cost can easily exceed 10,000.

■ Extended information: The engine needs to drink "engine oil" and the additives are redundant.

Having said that, Bian Xiao would like to share his views on petroleum additives. Gasoline additives may be familiar to everyone. However, according to the psychology of car owners, many engine oil additives with the signs of "reducing engine wear" and "cleaning up carbon deposits" have also been introduced in the market. Bian Xiao advised everyone not to try it easily. The reason is that engine oil is a mixture and contains scientific formula additives, so there is no need to reinvent the wheel. However, different formulations of engine oil have different components, and additives are easy to cause different chemical reactions, leading to engine oil deterioration.

■ Don't worry too much, just watch the fun.

In fact, after seeing the shady story of "adding sugar", Bian Xiao once asked senior experts in the auto repair industry for advice on the authenticity of this information. The answer is the same: I haven't heard of it, but I don't expect anyone to do it. It is speculated that the owner met the villain to plot against him, or even just the wanton revenge caused by the personal emotion of the maintenance worker. However, after media fermentation, individual behaviors are exaggerated. With the continuous standardization of the automobile market, 4S stores will pay more attention to their own credibility and reputation. Paper with sugar can't cover the fire, which is obviously a joke. No one is stupid enough to do this, so don't worry too much. It's just that the automobile publishing house comes out every March 15 to create momentum.
