Is Castrol Magnetec a Fully Synthetic Oil?

[Jill]

Castrol Magnetec is classified as a fully synthetic oil. Additional information about fully synthetic oils is as follows: 1. The process of achieving desired molecular structures through chemical reactions under controlled conditions is referred to as synthesis. 2. The largest component of motor oil is the base oil. According to specification grades, base oils can be divided into five categories. Only Category IV and V base oils can be termed synthetic oils, with Category V being polyol esters (POE) and Category IV being polyalphaolefins (PAO). 3. Motor oils blended exclusively with Category IV and V base oils, without the addition of mineral oils, can be classified as fully synthetic oils.
