How to identify the authenticity of Castrol's new packaging engine oil

1. Fake engine oil is usually added with engine oil and downshifted oil, that is, non-genuine engine oil or waste engine oil is poured into genuine Castrol engine oil barrel, and its production cost is very low.

2. If it is put into the engine, it will cause irreversible damage, so we are all eager to use genuine Castrol engine oil.

3. First of all, friends should not buy brand engine oil with the attitude of "low price and high quality". As the saying goes, only if they buy the wrong engine oil, your price will be unprofitable. How can they sell you? They will naturally think of reducing costs, and the "price war" will begin after the finished product is reduced, and the quality is not guaranteed. Therefore, low-priced engine oil is not comparable, and this needs to be determined.

4. The key point is how to identify the true and false? Besides, I won't buy instruments for identification. Extreme protection, such as providing official anti-counterfeiting calls, direct dialing or SMS inquiry.

5. The words "extreme protection" on the front and back of Castrol packaging barrel are irradiated by ultraviolet rays, and Castrol watermarks will appear in Chinese and English.

6. Castrol engine oil bottle cap can rotate around 180 degrees without opening, which is an advanced technology that ordinary fake engine oil manufacturers do not have.

7. Pour a little Castrol oil (just a little, don't waste it) and dry it on the ground. In the small sun or summer, you can fall directly under the scorching sun. After drying, there are almost no traces of oil stains on the genuine Castrol, while fake engine oil or domestic engine oil will obviously leave oil stains of different colors. Synthetic engine oil has a better contrast effect.

Extended data

Shelf life

1. The easiest way to check the shelf life of automobile oil is to observe whether the viscosity of the oil changes, judge whether the smell of the oil becomes weak, and observe whether the color of the oil changes.

2. When observing the color change of engine oil, pay attention to the change of additives in engine oil. In addition, filter paper or electronic instrument can be used to check whether the automobile oil has passed the shelf life.

3. Engine oil is very sensitive to moisture in the air, ambient temperature and light. If exposed to the air for a long time and exposed to strong light, it will generally fail. Automobile engine oil that has passed the shelf life will cause great damage to the automobile engine. If the lubrication effect is not good, the cooling effect will also be affected.

Witches and spies

1, depending on the appearance of the package. The famous brand oil cover is a disposable cover with sealed tin foil at the gap. The manufacturer marked the tin foil. Without these characteristics, it may be fake oil. In addition, brand-name oil is anti-counterfeiting, and there are special marks in inconspicuous places such as label stickers, tank bottom, inside of tank cover and handle. If criminals customize the packaging for fraud, they can tell by comparing the two packages.

2, is to observe the oil, the real oil color is light and transparent, no impurities, no suspended matter, no sediment, 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. There are generally three types of counterfeit engine oil:

(1) Filled with treated recycled waste oil;

(2) pure base oil is used for mixing without adding any additives;

(3) Buy low-grade oil and fill it with inferior oil. Generally, the color of fake lubricating oil is adjusted to be equivalent to that of real oil.
