How to Distinguish Between Full Synthetic and Semi-Synthetic Engine Oil?

[Guzman]

Methods to distinguish between full synthetic and semi-synthetic engine oil: 1. The packaging will indicate the type; 2. It can also be identified by color—semi-synthetic oil tends to be darker, while full synthetic oil is lighter. Strictly speaking, semi-synthetic oil can only be considered a mineral oil, as its production process involves adding a large amount of synthetic oil additives to a mineral oil base. While ensuring lubrication efficacy, it also performs well in functions like cleaning and repair. Full synthetic oil is artificially synthesized through chemical processes. During production, different formulations are used depending on the intended purpose. It excels in lubrication, cleaning, and repair capabilities, has a longer oil change interval, and offers better adaptability to environmental conditions.
