How to Identify the Authenticity of Engine Oil?

[MacAndrew]

There are four methods to distinguish genuine from fake engine oil: observing the appearance of the oil; analyzing the viscosity of the oil; judging by the sound of the engine; and smelling the oil. Specific methods for identifying genuine and fake engine oil: Determine the authenticity of the oil by its packaging. The methods and approaches that can be used are "one touch, two scans, three picks": One touch: Feel the packaging for raised striped flakes; Two scans: Use a mobile phone to scan and compare the color ratio, angle, and distribution of the striped flakes to see if they match; Three picks: Pick out the flakes to complete the genuine product identification. Alternatively, official verification via a verification code can be used. Analyze the viscosity of the oil. Good oil is relatively thin to a certain extent, and there are no granular substances when rubbed by hand, while inferior oil may contain some granules. After all, fake oil is basically refined from waste oil, so it differs from oil formed in one process. Judge by the sound of the engine. When fake oil is exposed to high temperatures, it can become sticky. The higher the engine temperature, the stickier the oil becomes, and in severe cases, the oil can burn and turn into sludge. The sound of an engine with genuine oil is relatively uniform, without any noise, whereas fake oil produces a more chaotic sound. Smell the oil. Genuine oil has a faint, pleasant fragrance. Generally, engine oil is composed of base oil and additives. Except for mineral oil on the market, other types of oil basically contain chemical additives, which are 0.6% aromatic hydrocarbons. The intensity of the smell varies depending on the oil. If the oil has a pungent smell, it can be judged as fake oil.
