Do you know how to distinguish between good and bad engine oil? Can you teach some tips?

The main thing is to look at the model.

In general, fully synthetic motor oil is used for turbocharging.

Naturally inhaled semi-synthetic.

Generally large brands are OK.

At present, the highest grade oil on the market is fully synthetic oil, synthetic era lubricating oil is currently many lubricating oil brands at home and abroad, a brand that only does fully synthetic lubricating oil, can be directly selected.

Motor oil is undoubtedly the blood of a car. Good engine oil can maintain the car to a certain extent, while poor quality engine oil can cause varying degrees of damage to the car. Because of this, the method of oil selection is very important. Here are some simple and useful identification methods for you.

One: Packaging. In general, the packaging appearance of motor oil is distinguishable.

The sealing cap of the brand-name oil is a disposable cap, and there is a sealing foil at the gap, and the foil has a manufacturer's special logo. If there is no such thing, the description is unprofessional, it may be fake oil, if there is a famous brand oil, there is also an anti-counterfeiting mark.

Second, look. Both real oil and good oil color are transparent, free of impurities and suspended solids. When shaking, it can be seen that the fluidity does not agglomerate. If it is a fake or low-quality oil, it may have deposits and opacity, or clumps.

Third, smell.

In general, motor oil is blended with base oils and additives. If mineral oil is used as a synthetic oil, it is most convenient and reliable to identify by smell. Generally, the smell of motor oil is milder. If there is a pungent odor, especially if the smell of fuel is heavy, it may be **oil.

Fourth, shake. A good engine oil will produce certain bubbles after shaking vigorously. If the bubbles slowly disappear, it may be a low-quality engine oil because a good oil has good fluidity.

The verb (short for verb) touches.

If it is a good oil, dip it directly with your hand and twist it, and you should feel that the oil is smooth. If it is an inferior oil, it will appear very sticky, with granular rubber-like hu, poor viscosity, and even astringency. So, it's also a simple and effective way to do it.

Of course, if you want to avoid some worries, you can choose to go to a reputable store to buy products from well-known lubricant brands, which is a more worry-free approach.

Millions of car purchase subsidies.

The oil label consists of two parts: grading and viscosity specification. The oil designation usually indicates viscosity and quality. The specific interpretation is as follows: the viscosity of lubricating oil is mostly marked by SAE and other grades, and SAE is the abbreviation of the English "Society of Automotive Engineers".

Look at the label, such as 5w-30, the smaller the front is the better, the bigger the back is the better, the front 5 represents low temperature resistance, and the back 30 represents high temperature mobility, of course, the fit is the best, it depends on what region you have, what season, what car.

Good oil has no odor.

Good liquidity and high transparency are the first points of inspection.

Look at the clarity of the oil ......The viscosity is ......

Depending on the color of the oil, the base oil is as clear as mineral water, and of course the clearer the better.
