What is the difference between Castrol Magnetec and Castrol Edge?

[StNadia]

Magnetec is a semi-synthetic oil, while Edge is a fully synthetic oil. The specific differences between the two are as follows: 1. In terms of base oil, Magnetec's base oil is hydrotreated Group III oil, while Edge 0w series has 100% Group IV base oil, and the 5w series has a mixture of Group IV and hydro-cracked Group III base oils. 2. In terms of engine protection, Edge provides comprehensive engine protection. Its API/viscosity grades are SN/0W-40, SN/5W-40, SN/5W-30, and SN/10W-60. Here is additional information: 1. How to choose engine oil. When selecting engine oil, the main consideration should be its viscosity index. Speed, engine load level, and temperature are the three main factors in choosing viscosity. The higher the speed, the lower the viscosity oil you should choose. The higher the load, the higher the viscosity oil you should choose. The higher the temperature, the higher the viscosity oil you should choose. 2. How to identify engine oil quality. The quality of engine oil depends on: base oil and additives. The quality of base oil depends on: crude oil source and refining technology, as well as synthetic process technology.
