Colorado mechanics provide tips on how to remove contaminated gas from vehicles
King Soopers is continuing to clear out contaminated gas at multiple gas stations in Colorado.
Contaminated fuel was sold at multiple gas stations in the Denver metro area, including Costco, Murphy Express, and King Soopers. Some customers had already purchased the contaminated fuel before the affected fuel lines were shut down, raising concerns about its impact on their vehicles.
Top Edge Automotive mechanics say removing the tainted gas will cost drivers thousands, but recommend getting an expert to fix it. It can cost anywhere from $5,000 to $20,000, even with an expert's help. However, it could cost vehicle owners more if they do it themselves, especially if they are not experts, don't have the tools or even the pieces.
Mechanics say owners will first notice tainted gas in their car's system by how the car feels. It will feel rough and even misfire. This happens because of fuel being mixed up with diesel; unburned fuel mixed with regular fuel.
To get it fixed, mechanics must pump out the contaminated fuel or remove it from the tank. The longer the bad fuel is in a car, the more damage it causes to the car, costing even more.
"This will cause your vehicle to stall, and you don't want to on the interstate," Mark Meiners, Co-Owner, Top Edge Automotive. "Never wait."
Experts say they can service and repair a vehicle with contaminated fuel in a day if they have all the parts.
