How to distinguish fake shell engine oil? Is it useless if the color is different?

You can do this in the following ways:

1, look at the packaging appearance:

The packaging of real engine oil is neat, without stubble, the sealing cover is disposable, and the packaging box is brightly colored, while the outer packaging of fake engine oil is rough and the color is dim. In addition, many real oil gaps have sealed tin foil, which will have the special logo of the corresponding manufacturer. Be sure to check carefully when buying oil.

2. Observe the appearance of oil:

Look at the color first. At room temperature, the color of real engine oil is much darker than that of fake engine oil. True oil is light and transparent, contains no impurities, suspended matter and sediment, and has good fluidity when shaking. Fake oil or oil is dark in color, or has impurity precipitation, or has strong pungent taste, poor fluidity when shaking, or has hand drawing.

3. Look at the price:

The real oil price is relatively stable, generally with little difference. Some stores have the reputation of genuine oil, or buy engine oil online and see comments that it is genuine, but if the price is too different from others, the owner should be careful.

4. Smell and feel:

The real oil tastes light, with a little fragrance of crystal wax, while the fake oil tastes strong and exciting. Oil products with the same viscosity grade have low hand viscosity at room temperature; Inferior oil products are sticky to the touch, and fake oil has wire drawing by hand.

5, freezing method:

If you really want to check whether the car bought real engine oil, you can put a little engine oil in a paper cup and then put it in the refrigerator at-15 degrees Celsius for 48 hours. After freezing for 48 hours, the genuine engine oil will show good low-temperature fluidity, but the transparency and color will not change obviously, while the fake engine oil will appear slightly viscous and turbid.

6. Manufacturer's official anti-counterfeiting certification:

In order to prevent counterfeit products, manufacturers have taken great pains. They either design anti-counterfeiting marks on the bottle body or design anti-counterfeiting marks on the bottle cap. Some are affixed with laser anti-counterfeiting labels, and some use some high-tech anti-counterfeiting means, such as anti-counterfeiting labels, anti-counterfeiting two-dimensional codes, product serial numbers, special labels, official website, customer service telephone numbers, SMS verification, etc. As long as it is verified by snacks, the probability of buying fake engine oil can also be avoided.

7. Shake the oil:

Shake the oil drum to see whether the oil has good fluidity and whether the oil bubbles disappear soon. Shake the oil to see if it bubbles. Generally, the bubbles of fake oil disappear slowly because there is no defoamer or the defoamer has failed. This oil can also cause damage to the engine.
