How to Identify Genuine Engine Oil?
1 Answers
There are several methods to distinguish genuine engine oil from counterfeit ones, which include: 1. Identifying by smell. Genuine engine oil has a faint, pleasant fragrance, as it is generally composed of base oil and additives. Except for mineral oil on the market, other types of engine oils basically contain chemical additives, i.e., 0.6% aromatic hydrocarbons, whose odor intensity varies depending on the oil quality. If the engine oil has a pungent smell, it can be judged as counterfeit. 2. Analyzing the viscosity of the engine oil. Good engine oil is relatively thin to a certain extent and has no granular substances when rubbed by hand, while inferior engine oil may contain some granules. After all, counterfeit engine oil is mostly refined from waste oil, so it differs from the one-time formed product. 3. Judging the authenticity of engine oil by its packaging appearance. The methods that can be adopted are 'one touch, two scans, three picks': One touch: Feel whether there are embossed stripe sequins on the outer packaging; Two scans: Use a mobile phone to scan and compare the color ratio, angle, and distribution of the stripe sequins; Three picks: Pick out the sequins to complete the genuine product identification. Alternatively, official verification through a verification code can be used. 4. Judging by the sound of the engine. When counterfeit engine oil is exposed to high temperatures, it may become sticky. The higher the engine temperature, the stickier the oil becomes, and in severe cases, it may lead to the oil being burnt into sludge. The sound of an engine with genuine oil is relatively uniform without any noise, while counterfeit oil produces a more chaotic sound.
