Group I oils are derived from paraffinic crude oil and still can be used in multiple applications. They are the most cost-effective base oils on the market.

Group I base oil stocks contain greater than 0.03% sulfur, less than 90% saturates and have a viscosity index 80-119.

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.

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