The nine Giant convenience stores and service stations in Santa Fe converted to Speedway during May, the latest outcome in a series of mergers involving petroleum companies in Arizona, Ohio and Texas.

Along with Speedway signage, the company has also given the stations technology upgrades.

“Customers will also see EMV (chip credit card reader) dispenser upgrades, bringing consumers enhanced security features, including encrypted credit and debit card technology, the latest in payment security features to help keep consumer personal information more secure, and enhanced safety from skimming devices,” the company said in a prepared statement.

The Santa Fe changes come as 115 Speedway stations in New Mexico started to appear April 23, mostly across the northern half of the state. This is the result of Findlay, Ohio,-based Marathon Petroleum Corp.’s Oct. 1 acquisition of San Antonio-based petroleum company Andeavor for $23 billion.

Speedway is an Enon, Ohio,-based subsidiary of Marathon, one of the 10 largest U.S. petroleum companies.

“We’re now in southwest Texas, we are going to start in Arizona soon and New Mexico of ‘re-IDing’ and developing those stores to the Speedway mark,” Marathon Chairman and CEO Gary Heminger said in a recent earnings conference call.

Andeavor, once known as Tesoro Corp., acquired Western Refining of El Paso in June 2017. Western Refining in 2006 had acquired Scottsdale, Ariz.,-based Giant Industries and kept the Giant service station brand in place.

Speedway had about 2,800 convenience store/gas station locations, adding 1,100 more with the Andeavor acquisition. That brings the Speedway count to nearly 4,000, including the westward expansion into New Mexico and Arizona, Speedway President Anthony Kenney told a Rotary Club in Ohio, according to a story in the Springfield News-Sun newspaper.
