What Type of Engine is Suitable for Full Synthetic Oil?

[Corbin]

Turbocharged engines are most suitable for full synthetic oil. Here is some relevant information about full synthetic oil: 1. Full synthetic oil indeed performs exceptionally well, with excellent fluidity. It excels in both cold starts during winter and high-temperature resistance in summer. Additionally, it has a long oil change interval, providing maximum protection for the engine. 2. Full synthetic oil is not suitable for micro or small cars priced at tens of thousands of yuan. The engine machining precision in micro and small cars is relatively low, and the sealing between the cylinder and piston rings is not the most precise. This type of engine is often found in lower-cost models, which require thicker oil to seal the gap between the cylinder and piston rings. If thinner full synthetic oil is used, there may be minor sealing issues in such engines, leading to a perceived lack of power when driving.
