As China's automobile production and sales increase, the lubricant market presents huge business opportunities, and some unscrupulous traders and manufacturers have also started to produce counterfeit lubricants. If car owners use inferior engine oil, it will not only affect the service life of the engine, but may also "break down" at any time, causing huge losses.
So how to choose the right lubricant? How to identify the authenticity of lubricating oil?
1, see packaging
Generally speaking, the appearance of engine oil packaging can be distinguished. The cover of famous brand oil is a disposable cover with sealing tin foil at the gap. The tin foil has special markings from the manufacturer. If there is no such thing, it indicates that it is unprofessional and may be fake oil. If there are famous brand oils, they usually have anti-counterfeiting marks.
2, check oil product
Real engine oil and good engine oil are transparent in color, without impurities and suspended solids. When shaken, it can be seen that the oil has good fluidity and does not agglomerate. If it is fake or inferior engine oil, there may be sediments and opacity, or there may be agglomeration.
3, smell
Motor oil is generally made from a blend of base oil and additives. If the motor oil on the market is mineral oil pretending to be synthetic oil, it is most convenient and reliable to identify it by smelling it. Generally, the smell of engine oil is relatively mild. If there is a pungent smell, especially a strong smell of fuel, it may be regenerated oil.
4, hand crank
Good engine oil will produce certain bubbles after vigorous shaking. If the bubbles disappear slowly, it may be inferior engine oil, because good engine oil itself has good fluidity.
5, frozen test
The freezing method is also an indispensable method. If possible, pour half a bottle of engine oil into a transparent container and seal the bottle mouth, and tie it tightly with multiple fresh-keeping bags to prevent the oil from leaking and contaminating the refrigerator. Engine oil is toxic. Put it in the freezer for a few hours. It must still flow at a low temperature of -20 degrees and must not freeze, otherwise it will be fake lubricating oil.
6, touch with hand
If it is a good engine oil, dip it in with your hands and twist it, you should feel that the oil is very smooth and moisturizing. If it is an inferior engine oil, it will be very viscous, with particles of impurities, poor viscosity, and even astringent. Therefore, this is a simple and effective method.
Now, I believe everyone has a basic understanding of the difference between genuine and fake lubricants.
