Colorado Fuel Contamination Crisis Strands Drivers
Locales: Colorado, UNITED STATES

DENVER, CO - January 29th, 2026 - Colorado drivers are grappling with a significant fuel contamination issue that has left vehicles stranded and repair shops overwhelmed. Reports of rough-running engines, stalled cars, and complete vehicle failures have surged across the state, impacting at least 20 gas stations and prompting an investigation by the Colorado Oil and Gas Conservation Commission (COGCC).
Mike Ward, service manager at a busy Denver auto repair shop, described the situation as "swamped." "We've been seeing a constant stream of vehicles with fuel-related issues," Ward stated. "Everything from cars that simply won't start to those exhibiting erratic performance - hesitation, rough idling, unusual noises. The common thread is fuel contamination."
The COGCC believes the contamination originates from a single source, but the precise location and nature of the contaminant are still under investigation. Peter Witkin, spokesperson for the COGCC, assured the public that they are actively working with fuel suppliers and retailers to pinpoint the source. "We're focused on isolating the problem and preventing further contamination. A thorough investigation is underway to determine how this happened and ensure it doesn't repeat."
What Drivers Should Do
The primary advice from mechanics across the state is stark: if you suspect you've purchased contaminated fuel, do not drive the vehicle. Operating a vehicle with contaminated fuel can exacerbate the problem, potentially leading to more extensive and costly repairs. "Driving a car with contaminated gas can cause significant damage to the fuel pump, fuel lines, and even the engine itself," warned Ward. "It's simply not worth the risk."
Professional Repair is Crucial
While some drivers might consider a DIY fix, mechanics strongly recommend professional intervention. Attempting to address the issue without proper knowledge and equipment could lead to further complications. A comprehensive repair typically involves:
- Fuel Tank Drainage: Completely emptying the tank of contaminated fuel.
- Fuel Line Flushing: Removing any remaining contaminated fuel from the fuel lines.
- Fuel Filter Replacement: Installing a new fuel filter to prevent any residual contaminants from reaching the engine.
- Injector Inspection: Examining the fuel injectors for damage or blockage caused by the contaminated fuel. Cleaning or replacing the injectors may be necessary.
Why Additives Aren't a Solution
Many drivers, understandably eager to resolve the issue quickly and inexpensively, might be tempted to use fuel stabilizers or additives. However, mechanics caution against this approach. "While these products might offer a temporary improvement in some cases, they're not a guaranteed fix," explained Ward. "In fact, they can sometimes worsen the problem by reacting with the contaminant and creating a more complex issue. We've seen instances where additives have caused further clogging and reduced engine performance."
Reporting and Resources
Drivers who believe they have been affected by the contaminated fuel are encouraged to take the following steps:
- Contact the Gas Station: Inform the gas station where you purchased the fuel so they can investigate and potentially notify other customers.
- Report to the COGCC: File a complaint with the Colorado Oil and Gas Conservation Commission. This helps the commission track the extent of the problem and prioritize their investigation. You can find contact information and reporting forms on the COGCC website ([a placeholder for the actual COGCC website would be added here]).
- Consult a Qualified Mechanic: Have your vehicle professionally inspected and repaired by a certified mechanic.
The COGCC is committed to keeping the public informed about the progress of the investigation. Regular updates will be posted on their website and through media channels. While the situation is undoubtedly frustrating for Colorado drivers, authorities are working diligently to resolve the issue and prevent further disruptions.
