How to Identify Genuine or Fake Engine Oil?
1 Answers
You can determine whether engine oil is genuine or fake by examining the packaging appearance, observing the oil's appearance, smelling its odor, and conducting a freezing test. The detailed methods are as follows: 1. Examine the packaging appearance: Genuine new oil packaging is clean and neat, free from oil stains or dust. The cap is a one-time seal with a tin foil under the opening, which bears the manufacturer's special mark. If these features are missing, the oil might be fake. 2. Observe the oil's appearance: Pour out the oil and observe it. Genuine oil is light in color, transparent, free from impurities, suspended particles, or sediment, with a mild smell and good fluidity when shaken. Fake oil may be darker in color, contain impurities or sediment, have a strong and irritating smell, poor fluidity when shaken, or show a stringy texture when touched. 3. Smell the odor: Genuine oil has a very mild smell, resembling crystal wax fragrance, while fake oil is highly irritating. Oils of the same viscosity grade have a slight hand viscosity at room temperature, whereas inferior oils feel sticky. 4. Freezing test: Place both oils in an environment at -21 degrees Celsius for a period (a few hours). You will notice a significant difference in their fluidity: genuine oil still flows well, while fake oil almost solidifies.
