Is Fully Synthetic Oil Suitable for All Vehicles?

[DianaAnn]

Fully synthetic oil is not suitable for all vehicles. Economy cars, in particular, are not well-suited for fully synthetic oil. The manufacturing processes and technology of economy car engines are not as advanced, and using fully synthetic oil can hinder cold starts, affect sealing performance, and potentially lead to engine wear. Therefore, it is recommended to use semi-synthetic oil or the manufacturer-specified oil type for economy cars. To achieve better lubrication, humans have developed various oils through chemical synthesis based on base oils, known as chemically synthetic oils. Officially, synthesis refers to the process of achieving the desired molecular structure through chemical reactions under controlled conditions, which is termed as synthesis.
