Drivers In The Denver Area Faced Mechanical Failures After Fueling At Large Chain Stations That Sold Diesel-Contaminated Gasoline.
The case mobilized state authorities, generated hundreds of formal complaints, and opened negotiations regarding reimbursements and liabilities.
Drivers in the Denver metropolitan area, in the state of Colorado, faced mechanical failures and damages after fueling with regular gasoline contaminated with diesel.
The problem affected large chain stations, which received fuel out of specifications without being previously informed about the failure.

Luciano Hang revealed that Havan’s air fleet has already accumulated more than 20,000 landings, 10,000 flight hours, and 6 million kilometers traveled, and he says that without the planes, the company would never have grown so quickly.
Complaints concentrated on fuelings made between the afternoon of January 7 and the morning of January 8, a period identified by state authorities as the most sensitive.
In light of the succession of reports, the Colorado Division of Oil and Public Safety, linked to the state’s Department of Labor and Employment, opened a formal investigation.
Within a few hours, the agency had already accumulated more than 200 consumer complaints, the majority reporting failures shortly after leaving the station.
Records describe cars that lost power, began to shudder, and in some cases, stopped completely shortly after leaving the pump.
Origin Of Fuel Contamination
The initial investigation pointed to a terminal operated by HF Sinclair, located in Adams County, as the origin of the problem.
The terminal is responsible for the logistics of fuel distribution to different retail chains in the region.
According to state authorities and local reports, out-of-specification shipments were loaded and sent to stations selling regular gasoline.
Upon arriving at the destinations, the inadequate fuel was unloaded into tanks designated for regular gasoline, where it mixed with the existing product.
As a result, the entire available stock ended up contaminated, without any immediate alert to the station operators.
Drivers, in turn, fueled normally, without any risk signage at the time of payment or when releasing the pumps.
Operational response began when complaints began to multiply consistently.
The first station with clear indications of the problem was identified about an hour after the initial reports.
This identification allowed for the interruption of sales at suspected units and initiated sample collection for technical analysis.
Affected Stations And Involved Chains
The first public communications mentioned stations belonging to widely recognized brands.
Among them were Costco, King Soopers, and Murphy Express, cited in consumer reports and local news.
As the investigation advanced, the list of potentially affected locations was gradually expanded.
The state began to disclose addresses and contact information to guide drivers who believed they had been affected.
Meanwhile, the number of incidents grew rapidly.
Authorities reported that the investigation began to handle hundreds of formal complaints, surpassing the initial volume.
The total number of records exceeded 200 cases, characterizing an episode of large scale for local standards.
Meanwhile, the definition regarding reimbursement for damages faced by consumers began.
Representatives of the state government informed that HF Sinclair agreed to reimburse affected customers.
At the same time, retailers and insurers began discussing procedures, timelines, and the documentation required to prove damages.
Why Diesel Causes Immediate Failures In Gasoline Cars
Vehicles designed to run on gasoline are not equipped to receive diesel in the fuel system.
Due to distinct physical and chemical characteristics, diesel compromises the proper burning of fuel.
This difference directly interferes with the functioning of essential vehicle components.
Among the most affected are fuel pump, lines, and fuel injectors.
Symptoms usually appear quickly because the wrong fuel starts circulating in the system shortly after fueling.
For this reason, many drivers reported failures within the first few kilometers driven.
In some cases, problems arose just when trying to start the car after filling the tank.
The extent of the damage varies depending on the volume fueled, the time of vehicle use, and the type of injection system.
Workshops and assistance networks consulted by local vehicles indicated that the initial repair involves complete cleaning of the tank and system.
In the United States, estimated costs start at around US$ 1,000 to US$ 1,500.
These amounts can increase significantly if there is a need for replacement of parts or damage to more expensive components.
