Your Colorado Energy Partner for Reliable Fuel Solutions
Fleet Core isn’t just dropping off fuel and driving away. We’ve spent years understanding how Aurora’s diverse operations work. From Buckley Space Force Base contractors to Centrepoint development projects, we can handle the demands with timely on-site fuel delivery. That means knowing when to pre-position fuel for winter road maintenance, how to schedule deliveries around harvest windows for eastern plains operations, and why construction crews need access before sunrise.
Our team manages everything from bulk diesel delivery for heavy equipment to gasoline for light-duty trucks, delivered on your schedule. You’re not adjusting your workflow around fuel availability. We’re adjusting our delivery windows around your operational priorities. It’s that simple.
Why Choose Us
What Happens When Fuel Supply Becomes a Non-Issue?
Fleet Core has been managing energy delivery for Aurora operations since before the city’s eastern expansion really took off.

Diesel Fuel Testing
Know Your Fuel Quality Before Problems Start
Beyond just delivery, Fleet Core handles the full lifecycle of your fuel systems. We’re talking storage tank maintenance, contamination prevention, additive programs for Colorado winters, and testing that catches problems before they sideline your equipment. You get one partner managing energy confidence, control, and continuity across every aspect of your operation.
Fuel Polishing
Clean Fuel Means Fewer Equipment Failures
Tank Cleaning
Protect Your Investment With Regular Storage Maintenance
Fuel storage tanks accumulate sludge, water, and bacterial growth that compromise fuel quality and tank integrity. Professional tank cleaning prevents costly contamination issues, extends tank lifespan, and ensures you’re meeting inspection requirements without scrambling during an audit.
Spill Cleanup
Take Fast Action When Spills Happen With Petro BusterEco-Friendly Cleaning Solutions
Fuel spills happen – during equipment maintenance, accident scenes, or tank transfers. Petro Buster petroleum cleaner handles the mess quickly, breaking down oils and fuels without harsh chemicals that damage surfaces or complicate disposal. Municipal operations especially appreciate how it simplifies cleanup compliance after vehicle accidents or hydraulic line failures.
Oil Analysis
Identify Breakdowns BEFORE They Happen
Knowing what is going on in your engine can be the difference between a successful delivery and a thousand-dollar tow. Our expert oil analysis can help you spot an issue before it leaves you broken down by the side of the road.
