Recently, multiple gas stations across the Denver-metro and Front Range regions were confirmed to have sold contaminated fuel—including diesel being pumped into gasoline tanks and fuel mixes that don’t match customers' expectations. In some cases, vehicles have experienced severe performance issues or even complete breakdowns shortly after fueling. (CBS News)
According to local reporting, fuel delivered to gas stations in Aurora, Broomfield, Erie, Parker, Castle Rock, and other areas was contaminated, possibly due to a delivery mix-up by a third-party carrier. (The Drive & El Balad) 
Social media reports and mechanic crews also indicate a significant uptick in vehicles with engine-performance problems immediately after fueling being brought in for service — a sign that many drivers may have unknowingly put the wrong fuel in their engines. (Reddit)

If you think you’ve been affected, here’s what to do next:

1. Stop Driving Immediately
If you suspect your vehicle was filled with contaminated fuel (e.g., diesel in a gasoline tank), do not continue driving. Driving even a short distance with bad fuel can circulate contaminants through your fuel system, potentially damaging the fuel pump, injectors, sensors, and engine components. Stopping early helps prevent further harm and reduces repair costs. Your vehicle must be towed before further damage occurs.

2. Report the Issue to the Gas Station and the State of Colorado
Contact the gas station where you fueled your vehicle and inform them of the problem. Many stations are actively working with customers to resolve complaints.
Additionally, the Colorado Division of Oil and Public Safety recommends that anyone who believes they’ve received contaminated fuel file an official complaint online or by calling 303-866-4967. This ensures the state can conduct a proper investigation and helps other drivers avoid the same issue.

3. Save Your Receipt 
Always save your fuel purchase receipt—it’s proof of purchase and supports insurance claims and documentation for fuel-station or state complaints.

4. Notify Your Insurance Provider
Contact your insurance provider promptly to report the situation and inquire about potential coverage for diagnostic fees, towing, or mechanical repairs. They can guide your next steps based on your policy.
