Get Fuel When and Where You Need It
We Know Fuel. We Know Commerce City.
Fleet Core has built our reputation on something pretty straightforward: showing up when we say we will with the fuel quality you need. We’re owner-operated, which means when you call, you’re talking to people who understand that your downtime isn’t just inconvenient—it costs real money.
Our Commerce City clients range from construction crews working the I-70 corridor to municipal fleets keeping public services running. We’ve seen what happens when fuel suppliers treat delivery like a commodity transaction rather than a partnership. Equipment damage from contaminated diesel. Projects delayed because brokers can’t coordinate deliveries. Budget overruns from fuel that doesn’t meet spec.
That’s not how we operate. Every gallon we deliver comes with decades of industry knowledge and a commitment to keeping your operations moving. Whether you’re running generators at a data center or fueling a fleet of trucks, we treat your fuel supply as the critical resource it is.

Fuel Polishing
Clean Fuel Means Equipment That Actually Starts When You Need It
Fuel polishing removes water, sediment, and microbial contamination before they damage your engines or generators. We use a proven filtration process that restores stored diesel to specification, preventing costly repairs and ensuring your backup power systems work during emergencies.
Tank Cleaning
Storage Tanks Full of Sludge Results in Equipment Nightmare
Fuel storage tank cleaning removes accumulated sediment, microbial growth, and water that settle at tank bottoms over time. Professional cleaning restores fuel quality, prevents filter plugging and injector damage, and ensures your stored diesel remains ready for immediate use when operations demand it.
Spill Cleanup
Be Ready for When Spills Happen with Petro Buster Eco-Friendly Cleaning Solutions
Petro Buster tackles petroleum spills on contact, breaking down oil and fuel residues without harsh chemicals or environmental damage. This heavy-duty cleaner handles everything from minor equipment leaks to significant spill events, giving you a fast, eco-conscious cleanup solution that meets regulatory requirements.
Oil Analysis
Catch Engine Problems Before They Become Catastrophic Failures
Oil analysis on your vehicles and mission-critical equipment reveals wear patterns, contamination, and degradation that predict failures weeks or months in advance. By testing lubricants regularly, you extend equipment life, reduce unexpected downtime, and make maintenance decisions based on actual conditions rather than guesswork.

Protect Your Equipment With Our Essential Fluid Services
Fleet Core delivers more than fuel, we deliver the operational confidence that comes from working with a supplier who understands what’s actually at stake. When your equipment sits idle waiting for a broker’s subcontractor to show up, you’re losing money. When contaminated fuel damages injectors or generators, you’re facing repair bills that dwarf any per-gallon savings.
We’ve structured our fuel delivery solutions around preventing exactly those scenarios. Direct supply means quality control from our storage to your tank. Local operations mean response times measured in hours, not days. Owner-operated accountability means someone actually cares whether your delivery arrives on time.
That’s the partnership difference. Ready to work with a fuel supplier who treats your operations as seriously as you do?
