How to Identify the Authenticity of Engine Oil?

[VanNova]

There are four methods to distinguish genuine from fake engine oil: observing the oil's appearance; analyzing the oil's viscosity; judging by the engine's sound; and smelling the oil. Specific methods for identifying genuine engine oil: Determine the authenticity of engine oil by its packaging. The method can be summarized as "one touch, two scans, three picks": One touch: Feel the packaging for raised stripe patterns; Two scans: Use a phone to scan and compare the color ratio, angle, and distribution of the stripe patterns; Three picks: Pick out the patterns to complete genuine product identification. Alternatively, official verification codes can be used for authentication. Analyze the oil's viscosity. High-quality engine oil is relatively thin to a certain extent and feels smooth without granular substances when rubbed between fingers, whereas inferior oil may contain particles. Fake engine oil is typically refined from waste oil, hence differing from newly formed oil. Judge by the engine's sound. Fake engine oil tends to become sticky under high temperatures; the higher the engine temperature, the stickier the oil becomes, potentially leading to sludge formation due to burning. Genuine engine oil ensures the engine runs smoothly with uniform sound and no noise, unlike fake oil, which produces a rough and noisy sound. Smell the oil. Genuine engine oil has a faint, pleasant aroma, as it consists of base oil and additives. Except for mineral oils on the market, most other types of engine oils contain chemical additives, specifically 0.6% aromatic hydrocarbons, which vary in scent intensity depending on the oil's composition. If the oil emits a pungent odor, it can be identified as fake.
