What grade is Shell HX6 engine oil?
1 Answers
Shell HX6 is a semi-synthetic grade engine oil. Semi-synthetic oil is one type of automotive engine oil, formulated using semi-synthetic base oil, specifically: internationally classified Group III base oil. It is a lubricant refined from mineral oil through hydro-cracking technology, composed of a 4:6 ratio blend of mineral oil and full synthetic oil. Engine oil, motor oil, or engine lubricants are substances enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. HX is Shell's engine oil series designation, where higher numbers following HX indicate higher grade levels within the series. Common examples HX5 and HX6 are known as Helix Yellow (also called Yellow Shell), representing Shell's higher-grade mineral oils.
