RICHLAND — Christensen, a leading distributor of refined petroleum products across the Pacific Northwest, announced on Tuesday it has purchased Boise-based United Oil.

According to a Christensen press release, the deal adds over 3,000 new customers to Christensen’s network. Both companies have more than 100 years of experience distributing fuel, oil, industrial lubricants and other speciality chemicals such as antifreeze, to farm, commercial and fleet clients across the region.

“The addition of United Oil and its entities support the Christensen growth strategy by strengthening our distribution network in one of the fastest growing markets in the county,” said Christensen CEO Tony Christensen. “We are excited to welcome the United Oil team and look forward to providing our quality products and differentiated services to customers in Idaho and Nevada.”

According to the United Oil website, the company runs convenience stores, pipeline terminals, oil storage facilities, bulk plants and truck repair facilities across southern Idaho, while Richland-based Christensen distributes to customers in Washington and Oregon from locations across Western Washington and Portland, Oregon.
