DENVER -- A convenience store chain in Colorado has been cited for selling regular gas as premium. And that's not all.
The business is also accused of having water in its gasoline storage tanks.
Everyday convenience stores are operated statewide by Superamerica LLC. There are five stores in metro Denver.
In July, state regulators got an anonymous consumer tip of allegations of substandard fuel being sold by Everyday stores.
"We investigated 19 Everyday store locations across the state and found that a large number of them failed," said Mahesh Albuquerque with the Colorado Oil and Public Safety.
"Smaller gas stations have been known to have water in their gas and things like that, so I tend to stay away from that for sure," driver Eric McDonald said.
Ten Everyday stores were found with violations, including ones in Denver, Parker, Westminster, Platteville, Durango, Colorado Springs, Lakewood and Pagosa Springs. All were selling midgrade or premium gas with substandard octane.
"I jump around to gas stations all the time and I never think that the quality differs," driver Brooke Payment said.
A store owner said he would talk on air but later could not be reached.
The Colorado Department of Revenue places a label on all gas pumps to make sure drivers are getting what they pay for.
"If they call that number, they actually contact our office and they can remain anonymous if they choose to," Albuquerque said.
Everyday was also cited for having excessive water in gas storage tanks. Water can also affect octane levels.AlertMe
