Hundreds of Coloradans are facing unexpected and costly car troubles after a fuel supplier distributed contaminated gas to 46 stations across metro Denver, ranging from Fort Collins to Colorado Springs. Colorado’s Department of Labor and Employment, which includes the Division of Oil and Public Sa fety, received more than 600 complaints from customers who bought gas contaminated with diesel that was delivered from an HR Sinclair terminal in Henderson on Jan. 8 and 9. Sinclair officials this week apologized and said they are investigating how the problem happened – which was not enough to ward off a proposed class action lawsuit filed by Littleton resident Ryan Mahon, who purchased 28 gallons for his Toyota Tundra from the Costco gas station in Englewood on Jan. 8. Kyle O’Brien, another metro Denver driver impacted by the contaminated fuel, got gas at the Costco near his home in Westminster early on Jan. 8 before driving his truck to work in Commerce City. “I got to work just fine and went to leave at 4 (p.m.) and it started really weak,” O’Brien said. “When I went to put it in drive, the engine just shut off.” O’Brien tried to figure out what was wrong by looking under the hood and checking the battery. He tried starting the truck again to find it was idling “wonky,” so he cleaned the throttle body, which seemed to help a little, and drove home. He made it back to Westminster after dealing with poor acceleration and more weird idling and tried to clean the mass air flow sensor before he called it a night. That’s when he saw news articles reporting the rash of contaminated gas across metro Denver. “I couldn’t help but laugh because at least it’s not something serious,” O’Brien said. “It’s not great, but at least the engine doesn’t need to be replaced.” O’Brien had his car towed to a shop near Costco and went to speak with a manager at the warehouse store, who immediately started working on his case. Costco is reimbursing his expenses – about $1,300 to drain and clean his truck’s tank and fuel line — but he had to pay for the up-front cost out of his own pocket.
