Understanding the Differences in Base Oil Groups.Best quality oil base house and trim coating. API Base Oil Definitions | Global Industrial Solutions. Base oils are used to manufacture products including lubricating greases, motor oil and metal processing fluids. Different products require different compositions and properties in the oil. One of the most important factors is the liquids viscosity at various temperatures. These three oil types all shared a common Group I base oil stock. 1952 API ASTM develop ESCS (Engine Service Classification System).It is from this initial definition that the Group IV PAO oils, as well as some other Group V oils like esters, were initially labeled as synthetic. According to the American Petroleum Institute (API), base oils fall into five main groups. This breakdown is based on the refining method and the base oils properties in terms of, among other things, viscosity and the proportion of saturates and sulfur content. API Base Oil Category.

According to the American Petroleum Institute (API), base oils fall into five main groups. This breakdown is based on the refining method and the base oils properties in terms of, among other things, viscosity and the proportion of saturates and sulfur content. Group V base oils are defined by API as any type of oil other than mineral oils or PAO lubricants.After that time, the term Middle East gained broader usage in Europe, the description Middle has also led to some confusion over changing definitions.

But, what I am looking for is how and when they came to be called Grp I, Grp II etc. I do not believe that the early oil industry called the early solvent refined oils According to the American Petroleum Institute (API), base oils fall into five main groups. This breakdown is based on the refining method and the base oils properties in terms of, among other things, viscosity and the proportion of saturates and sulfur content. Solvent refined base oils are commonly called Group I base oils which are characterized as those having less than 90 saturates (>10 aromatics) and more than 300 ppm sulfur.
