Does the quality inspection identify the authenticity of the engine oil?

You can see **, if ** is too cheap, it is very likely to be fake. The most reliable is to look at the anti-counterfeiting signs, and riders should pay attention to identifying the anti-counterfeiting signs.

Engine oil is something that many car owners often come into contact with, engine oil is very important for the engine, engine oil is known as the blood of the engine, and the engine oil not only plays a lubricating role in the engine, but also plays a role in cleaning, sealing, heat dissipation, buffering, and rust prevention.

If there is no oil in the engine, the engine will not work properly.

There are many riders who are worried about buying fake engine oil when changing the engine oil, so it is recommended that riders first buy engine oil from regular channels.

When buying engine oil, you can go to the local authorized dealer to buy it, or you can go to the official ** to buy, so that the probability of buying fake engine oil is very low.

When you are maintaining, you can also go to the 4S shop for maintenance, and the probability of using fake engine oil in the 4S shop is very low.

If fake oil is used, it will exacerbate the wear and tear of the engine, which will reduce the life of the engine.

If the oil is not changed for a long time, the lubrication performance of the oil will decrease, which will aggravate the wear and tear of the engine.

Every time you change the oil, change the oil filter as well. The oil filter cartridge filters the oil, which keeps the oil clean.

How to distinguish the authenticity of engine oil.

How to distinguish the authenticity of engine oil.

Local Quality Inspection Bureau. It costs money to identify it yourself.

There are several ways to distinguish the authenticity of engine oil, namely: 1. Distinguish by smelling the nose. Generally speaking, the composition of engine oil is composed of two parts: base oil and additives, and in addition to the mineral engine oil on the market, other types of engine oil are basically aromatic hydrocarbons with chemical additives, which is different due to the different odor depths of the oil, if the taste of the oil is more pungent, then it can be judged as fake engine oil.

2. Analyze by the degree of adhesion of the oil. Good engine oil is relatively thin to a certain extent, and there is no granular substance when rubbing it by hand, while there will be certain particles in the next little engine oil, after all, fake engine oil is basically refined from waste engine oil, so it is different from a one-time molding. 3. Judge 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 engine into mud.

Don't be a family car has been very popular, become a good helper for people's production and life, the car uses less viscosity engine oil, so that the oil circuit is smooth. For example, in the high temperature season or under the condition of severe engine wear, the selection of high viscosity oil is conducive to the formation of oil film and reduces engine wear.

1.Fully synthetic engine oil: Fully synthetic engine oil has better high and low temperature performance, longer oil change interval and is suitable for more severe car conditions, suitable for luxury high-performance vehicles, and is replaced at about 10,000-12,000 kilometers.

2.Semi-synthetic engine oil: The replacement cycle of semi-synthetic engine oil is generally about 8000-10000 kilometers, and the performance is moderate.

3.Mineral oil: This type of oil generally needs to be replaced after about 5000 kilometers.

Try to choose multi-grade oil, multi-grade oil has a better protection effect on the engine due to saving, long life and high efficiency. Based on the characteristics of multi-grade oil, premature blackening and oil pressure may be smaller than that of ordinary oil during use, which is normal.

1.Engine oil, that is, engine lubricating oil, can lubricate and reduce friction, assist cooling and cooling, seal leakage, rust and corrosion, shock absorption and cushioning for the engine. It is known as the "blood" of automobiles.

2.Engine oil is made up of two parts: base oil and additives. Base oil is the main component of lubricating oil, which determines the basic properties of lubricating oil, and additives can make up for and improve the shortcomings of base oil performance, give some new properties, and are an important part of the lubricating oil remorse.

3.The 5W W-30 and so on in the engine oil indicate the viscosity grade of the engine oil, which is the SAE grade. "W" means winter.

The smaller the number in front of w, the smaller its low temperature viscosity, the better the low temperature fluidity, and the lower the applicable minimum temperature. The number after w does refer to the viscosity of the oil at 100 degrees Celsius, and the higher the number, the more viscous the oil. The following figures mainly refer to the index of the high temperature resistance of the oil, and the better the protection performance at high temperatures.

There are mainly the following ways to distinguish the authenticity of engine oil, which are: 1. Distinguish by sniffing. Real engine oil will have a faint fragrance, generally speaking, the composition of 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 chemical additives, that is, aromatic hydrocarbons, which are different due to the different odor depths of the oil, if the taste of the oil is more pungent, then it can be judged as fake engine oil. 2. Analyze by the degree of adhesion of the oil. Good engine oil is relatively thin to a certain extent, and there is no granular substance when rubbing it by hand, while there will be certain particles in the next little engine oil, after all, fake engine oil is basically refined from waste engine oil, so it is different from a one-time molding.

3. Judge the authenticity of the engine oil through the appearance of the packaging. The methods and methods that can be adopted are "one touch, two sweeps, three picks": one touch:

Touch the outer packaging to see if there are striped sequins with a concave and convex feeling; Second scan: the mobile phone scans and compares the color proportion, angle, and distribution of the striped sequins; Three picks: pick out the sequins to complete the ** identification.

Or you can pass the official verification code verification. 4. Judge 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.

Engine identification.

Fake oil was used, and the car was running as usual at first. Whether it's power output, fuel consumption levels or noise vibrations, there's no difference. Only when there is carbon deposit, oil blockage, poor ignition effect of spark plugs, etc., you will know the reason for retrospectively, and it may be the use of fake engine oil.

There are two kinds of fake engine oil, one is the fake engine oil that is reprocessed with ** engine oil, and the other is to take a small brand of engine oil and fill it into a large brand of engine oil for sale.

There may be no way to directly distinguish the appearance, the most direct is to see whether there is a power of attorney or relevant qualification documents.

How to quickly distinguish a real from a fake motor oil?

The landlord can call the official ** for inquiries; The other thing is to pour some oil into a cup and put it in the refrigerator to freeze.

Three or four hours to see the fluidity and clarity. Cloudy, poor fluidity is fake motor oil.
