Some gas stations in the Denver metro area, including Costco, Murphy Express and King Soopers locations, sold contaminated fuel on Thursday, according to the Colorado Division of Oil and Public Safety. 

King Soopers confirmed to CBS News Colorado that the pumps at 14 of its gas stations in the Denver metro area contained contaminated fuel. That fuel was pumped into vehicles by customers.

According to a King Soopers company representative, multiple locations in Aurora, Broomfield, Parker and other cities were impacted. Store officials said the fuel was delivered by a third-party carrier.

One customer told CBS Colorado that the gas she pumped into her vehicle was contaminated with diesel.

Once the store learned about the contaminated fuel, officials said all affected fuel lines were shut down. Teams continued to work to complete the remediation process and get the pumps back online.

King Soopers released this statement, which read in part: We sincerely regret the inconvenience and disruption this has caused our customers. We understand how important reliable fuel service is, and we are committed to working directly with any impacted customers to resolve their concerns. Customers who believe they may have been impacted are encouraged to contact their local store and we will assist them promptly.

An earlier update from King Soopers had listed some locations in Boulder and Littleton but the company amended its location list to include five fewer locations, lowering the number of gas stations impacted to 14 locations. 

The Colorado Division of Oil and Public Safety released this statement to CBS Colorado: The Division of Oil and Public Safety began receiving complaints about bad gas on Thursday, January 8. Reports were coming from fuel sold at Costco, Murphy Express, and King Soopers locations, among others.

The Division understands that regular unleaded gasoline contaminated with diesel fuel was loaded from the HF Sinclair terminal in Henderson, Colorado and sent to numerous gas stations between 2 p.m. on January 7th through 6 a.m. on January 8th. On January 8th, the Division took a sample from the Costco gas station at River Pointe in Sheridan that confirmed the contamination. The Division will continue to work with station owners to test fuel samples and identify impacted retailers. Station owners are working quickly to stop sales of the contaminated gasoline and have it replaced with the right fuel.

Consumers are encouraged to contact the gas station if they believe they were impacted, and to contact the Division by submitting a complaint online or calling 303-866-4967 if they would like State assistance.

In February 2020, a gas station in Boulder was not fined following a mix-up with its fuel transfers. The State of Colorado said they dropped regular unleaded into the diesel compartment, or diesel underground storage tank, and dropped diesel into the regular unleaded storage tank, and then regular unleaded into the premium.
