Base Oil is the name given to lubrication grade oils initially produced from refining crude oil (mineral base oil) or through chemical synthesis (synthetic base oil). Base oil is typically defined as oil with a boiling point range between 550 and 1050 F, consisting of hydrocarbons with 18 to 40 carbon atoms. This oil can be either paraffinic or napthenic in nature depending on the chemical structure of the molecules.
Almost every lubricant used in plants today started off as just a base oil. The American Petroleum Institute (API) has categorized base oils into five categories (API 1509, Appendix E). The first three groups are refined from petroleum crude oil. Group IV base oils are full synthetic (polyalphaolefin) oils. Group V is for all other base oils not included in Groups I through IV. Before all the additives are added to the mixture, lubricating oils begin as one or more of these five API group

What are Base oil
The terms base stocks and base oils are often used interchangeably, but there are differences. A base stock is a single product, usually defined by its viscosity grade. A mixture of one or more base stocks in a finished lubricant is a base oil. A base oil is always defined in the context in the formulated lubricant. Base oil properties can vary depending on their API group.
What is the difference between Synthetic and Mineral oils?
Synthetic lubricants consist of molecules that have been modified through complex chemical processes, enabling enhanced performance under extreme conditions of temperature, pressure, and forces. Mineral lubricants comprise molecules present in crude oil that are separated during the distillation process at a refinery.
What is a multi-grade engine oil?
A multi-grade engine oil is one that meets more than one SAE specification. For example, SAE 20W40 must pass the viscosity grade requirement for both SAE 20W and SAE 40. The temperature range the oil is exposed to in most vehicles can be wide, ranging from cold temperatures in the winter before the vehicle is started up, to hot operating temperatures when the vehicle is fully warmed up in hot summer weather.ore
What is base oil interchange (BOI)?
Base oil interchange is a set of guidelines that allows the substitution of base stocks belonging to a specific base stock slate
