Starting with the fundamentals, there are five basic base stock categories:<a href=\"#_ftn1\"><sup>[1]<\/sup><\/a><\/p>\n\n<figure class=\"wp-block-image size-large\"><img fetchpriority=\"high\" decoding=\"async\" width=\"500\" height=\"220\" src=\"https:\/\/testoil.com\/wp-content\/uploads\/2020\/11\/api-base-oil-categories.jpg\" alt=\"API base oil classification\" class=\"wp-image-60156\" srcset=\"https:\/\/testoil.com\/wp-content\/uploads\/2020\/11\/api-base-oil-categories.jpg 500w, https:\/\/testoil.com\/wp-content\/uploads\/2020\/11\/api-base-oil-categories-300x132.jpg 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/figure>\n\n<ul class=\"wp-block-list\">\n<li>Group I base stocks are the least refined. They are usually a mix of different hydrocarbon chains, which is about all they have in common. These base stocks are not best for applications requiring high performance.<\/li>\n<li>Group II base stocks are common in off-the-shelf mineral-based motor oils. In terms of volatility, oxidative stability and flash\/fire points they are adequate. Where they struggle is extreme pressure, cold start viscosity and pour point performance.\u00a0<\/li>\n<li>Group III base stocks are the most highly refined of all mineral base stock groups. Group III base stocks generally perform well and are very stable. Lubricants that result from these base stocks are synthetic or semi-synthetic.<\/li>\n<li>Group IV base stocks are PAOs (polyalphaolefins). They are synthetic and chemically engineered with uniform molecular chains and very stable chemical compositions. These base stocks are becoming more and more common in synthetic and synthetic-blend fluids in industrial applications.<\/li>\n<li>Group V encompasses just about everything that is not included in the other four base stock groups. They are rarely used as base stock by themselves, but may be used in small quantities as secondary base stocks to impart certain custom properties. They are also used as base oils for additives.<\/li>\n<\/ul>\n\n<p>Most lubricants are a blend of at least one basestock and <a href=\"https:\/\/testoil.com\/data-interpretation\/keeping-an-eye-on-additives\/\" data-type=\"URL\" data-id=\"https:\/\/testoil.com\/data-interpretation\/keeping-an-eye-on-additives\/\">additives<\/a>. The chemical composition (mostly saturates and sulfur) of these basestocks, along with any additives determines how lubricants perform.
