Group II Base Oil

MaxPar^® G2 Base Oils

Resolute Oil's MaxPar G2 Group II paraffinic base oil products are refined and processed using modern technology and meet the highest standards for quality and performance. MaxPar G2 products are water-white, thermal- and UV-stable, and possess a high percentage of saturates and excellent purity. Defining characteristics of MaxPar G2 products are ultra-low in aromatics, sulfur, and polar compounds.

Our high-quality Group II domestic supply partners have the capability of shipping barge-sized loads of oil to Resolute Oil for storage in our Waller, TX production facilities. Each of our specially-lined storage tanks utilizes segregated piping to ensure consistent product quality and our inline blending equipment allows for specialized viscosity blends to meet our customers' exacting specifications.

All MaxPar G2 products meet or exceed FDA regulation 21 CFR 178.3620(c) and may be used as a component of nonfood articles that come in contact with food.

What Is Group II Base Oil?

Group II base oils are produced using modern hydroprocessing and catalytic dewaxing technologies.

The process begins with crude oil feedstock that undergoes atmospheric fractional distillation before being further distilled in a vacuum distillation tower. Vacuum gas oil (VGO) leaves the distillation tower and flows to a hydrocracker for further processing.

Inside the hydrocracker, hydrogen is introduced to saturate the waxy vacuum gas oil molecules and remove impurities like sulfur, oxygen, nitrogen, and heavy metals. During the process, aromatic molecules are converted to saturated paraffin molecules in the presence of a catalyst and under extreme temperature and pressure.

After hydrocracking is complete, the stream of oil passes through a catalytic dewaxing process, where waxy paraffin molecules are chemically restructured into isoparaffins. These isoparaffins are more resistant to gelling and have much better low-temperature characteristics.

A hydro-finisher wraps up the final step in hydroprocessing. Inside the hydro-finisher, hydrogen is reintroduced into the stream of oil to remove any lingering aromatics and impurities, which results in a finished product with a high viscosity index (VI), excellent oxidation, and thermal stability.
