Base Oils Group I

Group I base oil is produced by extracting and refining paraffinic crude oil. It is a liquid at room temperature and may have white to dark brown coloring. Group I base oil is not considered as dangerous goods. Nowadays base oils group 1 are the most cost-effective base oils on the market and can be used in multiple applications. You can check DYM Resources’s group 1 base oil specifications to find a product for your particular application.

Group I oils are produced by solvent extraction and dewaxing processes. Solvent extraction starts with a heavy refinery feedstock from a crude distillation unit that’s called vacuum gas oil. A very selective solvent removes much of the sulfur, aromatic and nitrogen compounds. The resulting oil stream comes out of the extractor still containing paraffins that need to be removed to make it a base oil. A light solvent is added and the mixture is refrigerated to a low temperature at which the paraffins precipitate and are filtered out.

Group 1 base oil stocks have more than 0.03% sulfur contents, less than 90% saturates and have a viscosity index 80-119. Its kinematic viscosity and flash points are also increased. Group 1 base oil colors are a light straw, except for the brightstock which is darker.

In spite of crude oil feedstocks being different for different refiners, similar viscosity grades of Group I base oils manufactured by different refiners have similar physical and chemical properties.

Base oils group 1 are transported in isotanks, flexitanks, trucks and stored in flexi tanks.

They are mostly used in industrial and marine lubricants and in engine oils for older engines.
