SuperAmerica, a convenience store chain founded in 1960 in St. Paul, will now be known as Speedway.

The change follows the recent merger of Marathon Petroleum Corp., the Ohio-based owner of the Speedway brand, and Andeavor, formerly known as Tesoro, which has owned the SuperAmerica brand since 2016.

Marathon CEO Gary Heminger told Fox Business in May the combined company, now the largest refiner in the U.S., will “take a Speedway platform coast-to-coast.”

“Andeavor had many brands they were using in the company-owned, company-operated system,” he said. “We will turn those into Speedway and have one system.”

Since the first SuperAmerica store opened on Seventh and Wall streets in St. Paul, the company has had a number of owners over the years — including, for a time, Marathon. This is the first time the Minnesota-bred brand has ceased to exist, however.

There are about 170 company-owned SuperAmerica locations and 114 franchised stores largely in Minnesota and Wisconsin, according to the company, with more than 2,000 employees in total.

Regular customers are asked to move their rewards card balance at www.speedway.com. The company says SuperAmerica gift cards will no longer be accepted; call 1-800-428-4016 to have balances refunded.

The SuperAmerica change follows last year’s sale of another prominent convenience store chain with Minnesota roots.

In July 2017, Bloomington-based Holiday was acquired by Canadian-based Alimentation Couche-Tard Inc.

Couche-Tard owns more than 14,000 convenience stores across the world, most notably Circle K.

However, the Holiday brand was retained after the sale and the headquarters remained in Bloomington. Holiday operates more than 500 stores throughout 10 states in the northern United States.

SuperAmerica and Holiday have a shared heritage in the family of Swedish immigrant Otto Erickson, originally from Isanti, Minn.

In 1939, six of Erickson’s grandsons bought a bankrupt Texas refinery and moved it to St. Paul Park, creating Minnesota’s first gasoline refinery, Northwestern Refinery Co.

According to the St. Louis Park Historical Society, the SuperAmerica brand, also known as SA, was coined by grandson Elmer Erickson, who opened the gas stations to sell the refinery’s fuel products.

Meanwhile, what became the Holiday brand was started 90 years ago by two of Otto Erickson’s other grandsons, Arthur and Alfred, with a rural general store and gas station.

The Erickson family also operated other gas stations under the Erickson Oil/Freedom Valu Center brands.
