How to Identify Genuine Engine Oil?
1 Answers
Methods to identify genuine engine oil: 1. High-quality oil has a smooth cap edge and a one-time sealing cap. If the cap is rough and lacks a pull-tab seal, instead requiring direct twisting to open, it is likely repackaged oil. 2. Check the anti-counterfeiting code on the barrel. Genuine oil has clear anti-counterfeiting markings. 3. Inspect the material and craftsmanship of the oil barrel. 4. Smell the odor and feel the viscosity. Common counterfeit oils include: 1. Reprocessed waste oil repackaged for sale. 2. Basic oil blends without any additives. 3. Low-grade oil repackaged as premium, with color adjusted to match genuine oil.
