What Is Group I Base Oil?

Group I base oils are produced through a solvent refining process and possess unique properties and characteristics that make them well suited for a wide variety of applications.

The solvent refining process begins with a sweet crude feedstock that undergoes fractional distillation before proceeding to a solvent extraction unit that removes much of the sulfur, aromatic, and nitrogen compounds.

After solvent extraction is complete, the stream of oil is sent through a dewaxing process to remove waxy paraffin molecules still present in the oil. The dewaxing process utilizes a lighter solvent in conjunction with a refrigerated chiller to precipitate and remove remaining paraffin content.
