The Difference Between Full Synthetic and Semi-Synthetic Engine Oil

[StJessica]

Semi-synthetic and full synthetic engine oils are two classifications of engine oil, with the specific differences as follows: 1. Full synthetic engine oil can be used in a wider range of temperatures and has a longer service life. For the same oil film requirements, full synthetic oil can achieve this with a lower viscosity, whereas semi-synthetic oil requires a relatively higher viscosity compared to synthetic oil to meet the same requirements. 2. Compared to semi-synthetic oil, full synthetic oil offers better high and low-temperature performance, a longer oil change interval, and is more suitable for harsher vehicle conditions. 3. Full synthetic oil requires fewer oil changes, but its cost is significantly higher than that of semi-synthetic oil.
