Which is Better: Semi-Synthetic or Full-Synthetic Engine Oil?

[Mila]

The choice between semi-synthetic and full-synthetic engine oil should be based on specific circumstances. Below is an introduction to these two types of engine oil: Differences between the two: Full-synthetic oil can operate over a wider temperature range and has a longer service life. For the same oil film requirements, full-synthetic oil can achieve the desired effect with a lower viscosity, whereas semi-synthetic oil requires a relatively higher viscosity to meet the same requirements. In other words, under the same working conditions, full-synthetic oil can protect the engine with a lower viscosity. Similarly, in the same working environment, full-synthetic oil lasts much longer than semi-synthetic oil. Although it is more expensive, considering the reduced frequency of oil changes, the cost difference compared to mineral oil is not significant. Examples of when to choose each type of oil: Performance cars and turbocharged models are not recommended to use semi-synthetic oil. Using semi-synthetic oil in these vehicles may result in insufficient engine cooling, leading to accelerated wear of components and rapid carbon buildup, while also failing to maximize the performance of turbocharged engines. Generally, naturally aspirated engines are more compatible with semi-synthetic oil. If your car has a naturally aspirated engine, it is advisable to use semi-synthetic oil.
