It is easy to distinguish between real and fake engine oil, and this time it is how to distinguish b

Genuine: The factory logo font on the surface of the filter is clearly printed, and the paint used for printing has a good texture and is pure white.

There is a bypass valve inside to ensure that there is a sufficient amount of oil in any state**.

The sophisticated backflow suppression design ensures that the filter has the oil necessary for the next start-up, reducing wear and tear during cold starts (a feature available on all genuine filters).

It is equipped with a protective bag before leaving the factory, there is lubricating butter at the interface, the sealing material of the gasket is good, and the rubber parts are regular.

The filter paper material is specially developed according to the oil used, and the density is moderate to ensure the filterability of the oil.

The metal oil mesh in the filter element is standard in shape to ensure the amount of oil throughput.

Fake: The font printing on the surface of the filter is blurry or not clear enough, and the font printing paint surface is inferior and thin.

Without a bypass valve, the engine would not receive sufficient oil lubrication if the filter was clogged.

There is no function to inhibit oil return after the ignition is turned off, and the engine wear will be greater during cold starts.

The sealing material of the gasket is poor, which may cause oil leakage under high temperature and high pressure, and even lead to **.

The filter paper is made of different materials, and it is difficult to achieve the desired filtration effect.

The workmanship of the metal oil mesh is rough, and it is difficult to ensure the abundant oil flow.

Hazards: The shoddy oil filter not only affects the normal oil supply and lubrication of the engine by the oil pump, but also due to the shoddy production, the interface of the main oil channel may be not tightly sealed, resulting in the oil jumping out on the joint surface of the filter and the cylinder block, which will cause oil leakage, poor engine heat dissipation and other failures, and in serious cases, the cylinder will burst.

Look at the paper quality and workmanship.

There are too many fake engine oils on the market, and it is impossible to prevent them, so the old drivers support: do this to avoid buying fake engine oil.

Need to check the anti-counterfeiting logo of the oil, generally big brands have anti-counterfeiting logos, or call the official ** of the engine oil manufacturer, before buying the engine oil, you must understand the oil model you need, otherwise the best oil will not match.

The smell of fake engine oil will be particularly heavy, and the color will be very different from that of real engine oil.

To distinguish between real and fake engine oil, you can call the **** behind the product and verify it by hitting **.

First of all, it is necessary to look at the outer packaging of the product, observe the appearance of the oil, and then look at the engine oil, smell the smell of the oil and touch the feel of the oil or shake the oil, and finally you can also verify the official anti-counterfeiting certification of the manufacturer.

<> "A few tips to distinguish the real from the fake engine oil!

As the lifeline of the engine, the engine is related to the safety and experience of the engine, as the engine is good or bad in terms of performance, the oil determines most of the oil, and the choice of oil is not very important.

There are many ways to distinguish the true and false of engine oil, first of all, the first method is to distinguish by smelling the nose, the real engine oil will have a faint fragrance, speaking of which is analyzed from the composition of the engine oil, generally speaking, the composition of the engine oil is composed of two parts: base oil and additives. In addition to the mineral engine oil on the market, other types of engine oil are basically aromatic hydrocarbons with chemical additives, which are different due to the different odor levels of the oil, if the taste of the oil is more pungent, then it can be judged as fake engine oil.

The second method, through the analysis of the degree of adhesion of the engine oil, a good engine oil is relatively thin to a certain extent, there is no granular substance when rubbing it by hand, and there will be a certain particle in the next point of engine oil, after all, fake engine oil is basically refined from waste engine oil, so there is still a difference from a molding.

The third method, judging by the sound of the engine, when the fake engine oil is subjected to high temperature, there will be bonding, the higher the engine temperature, the more sticky the oil will be, and in serious cases, it will lead to the ablatation of the oil into mud.

Finally, judging the authenticity of the engine oil from the appearance of the packaging, the method and method that can be adopted is "one touch, two sweeps and three picks".

One touch: touch the upper part of the outer packaging to see if there is a concave and convex striped sequin;

Second scanning: the mobile phone scans and compares the color ratio of the striped sequins, the angle of Knott, and whether the distribution of the sequins is consistent;

Three picks: pick out the sequins to complete the ** identification. Or you can go through the official verification code.

Summary: For the identification of the authenticity of engine oil, it is recommended to go to a professional official store for maintenance and purchase of engine oil, at least it is more true than buying it in some other ways.

In the current market, if a car buyer wants to buy a well-known engine oil, it is best to go to a professional store to carry out the purchase. Due to the high brand awareness of motor oil, there are usually a large number of counterfeit products, but car buyers must also know how to identify the authenticity of engine oil, so as to prevent the use of fake engine oil.

Once applied to fake engine oil, it will cause certain harm to the car. It is very likely that the fake engine oil does not have enough thick oil slick, which will cause the parts to deteriorate faster. It is also very likely that fake engine oil cannot assist in heat dissipation, which can easily cause the temperature of the car engine to be too high.

The cleaning properties of fake engine oil are poor, and the car engine cannot be cleaned better, which immediately leads to a reduction in the application time of the diesel engine.

9 ways to distinguish genuine motor oil.

1. Look at the packaging appearance: the packaging design of the real engine oil will be very exquisite, the workmanship is very neat, the sealing cover is a disposable cover, the opening has a sealed tin foil, and the tin foil has a unique logo of the manufacturer.

2. Observe the appearance of the oil: the real engine oil is light and transparent, without residue, suspended solids and precipitation. The oil color of fake engine oil is darker, and it is very likely that there will be residue, precipitation, or metal drawing by hand.

3. Smell: The smell of real engine oil is light, which is the aroma of amethyst wax; Fake engine oil will be more nasal choking.

4. Refrigeration test: If these two kinds of engine oil are placed in the condition of minus 21 degrees for a period of time (many hours), you will see that there is a significant difference in the fluidity of the two: the genuine engine oil still has effective fluidity, while the fake engine oil is basically solidified.

5. Engine oil price: the price of real engine oil is relatively stable, and it is generally not easy to differ too much.

6. Shaking engine oil: Shaking engine oil is observed to see whether the fluidity of the engine oil is excellent and whether the bubbles of the engine oil are fading quickly. The real oil has good fluidity when shaking, while the fake oil has weak fluidity when shaking, and the bubble fades slowly, because there is no antifoam agent in the oil or the antifoam agent has long been ineffective.

7. The manufacturer's official network anti-counterfeiting logo verification: there are anti-counterfeiting logos in the design scheme on the bottle or bottle stopper of the engine oil, some of which are pasted with laser anti-counterfeiting logos, and some are the application of some intelligent product anti-counterfeiting methods, such as official website, customer service, mobile phone SMS verification, unique logos, commodity serial numbers, anti-counterfeiting, and anti-counterfeiting logos.

8. Compare the anti-counterfeiting code and the qualified code: there is an anti-counterfeiting code on the top of the outer cover, and there is a qualified code below the anti-counterfeiting code, and the anti-counterfeiting code and the qualified code are consistent.

9. Application feeling: In the whole process of application, you can also observe the carbon deposition of the automobile engine, or whether there will be various common faults due to the use of engine oil, such as: serious damage to the automobile engine, increased fuel consumption, carbon deposit, and flutter.

<><4 ways to distinguish between real and fake engine oil

We all know that inferior and counterfeit engine oil products will not only bring harm to the car engine, but also cause serious economic losses to the car owner. So what are the 4 ways to distinguish real and fake motor oil?

1. Look**: The difference between real and fake engine oil is still quite large, if the engine oil is very cheap, you need to be wary of fake engine oil.

2. Smell the smell: The real engine oil will smell a very light fragrance, the taste of fake engine oil will be very pungent, and you can also feel a strong odor of diesel or gasoline.

3. Look at the color: the color and luster of the real machine will be very pure and transparent, without any impurities, precipitation and suspended solids, and the fluidity during shaking is also good. The color of the fake oil will be very mellow, showing a dark brown color, and there will be some sediment or suspended matter in the oil, and the fluidity during shaking will be poor.

4. Listen to the engine sound: During the use of real engine oil, the engine sound will be very uniform and there will be no noise. When the engine temperature is higher, the oil will become more sticky, and the situation will cause the oil to ablate into mud.
