Differences Between Full Synthetic Oil and Semi-Synthetic Oil?

[SanJake]

Here are the specific differences between full synthetic oil and semi-synthetic oil: 1. Different base oils: Semi-synthetic oil uses Group III base oil; full synthetic oil is a mixture of Group III, IV, and V base oils. Full synthetic oil has a higher grade of base oil selection compared to semi-synthetic oil. 2. Different replacement intervals: Semi-synthetic oil should be replaced every six months or 7,500 kilometers during use; full synthetic oil should be replaced every year or 10,000 kilometers during use. 3. Different operating temperatures: Full synthetic oil has a wider operating temperature range. Under the same working conditions, full synthetic oil can protect the engine with a lower viscosity, while semi-synthetic oil has relatively higher usage requirements.
