From construction sites near the Flatiron Crossing to fleet operations supporting Denver International Airport, we’ve seen it all and solved it all.
You know what sets us apart? We don’t just drop off fuel and disappear. Our team works alongside facility managers, construction supervisors, and fleet coordinators throughout the area to create custom solutions that actually make sense for your operation. Whether you’re managing a hospital’s backup generators or keeping a construction fleet moving on Highway 36, we bring the expertise that turns fuel management from a headache into a strategic advantage.
Complete Fuel Management Solutions Beyond Just Delivery
Fuel Delivery
On-Site Fuel When You Need It, Where You Need It
Professional fuel delivery eliminates downtime and keeps your operation running smoothly. Our mobile fuel trucks deliver premium diesel, gasoline, and off-road fuel directly to your equipment. No more sending crews across town to fill up tanks.
Diesel Fuel Testing
We Gaurantee The Quality of Our Fuel, Can You?
Prevent unnecessary wear and replacement of filters and disastrous replacement of fuel systems with fuel testing from Fleet Core. Professional diesel fuel testing reveals contamination, water content, and microbial growth before they damage expensive equipment. Our comprehensive analysis gives you the data needed to make informed decisions about fuel treatment, replacement, or polishing, because replacing a fuel system is way more costly than regular testing your diesel fuel.
Fuel Polishing
Clean Fuel Means Reliable Performance
Fuel polishing removes water, sediment, and microbial contamination that builds up in storage tanks over time. This process extends fuel life and prevents the gelling, clogging, and system damage that can shut down operations when you least expect it.
Tank Cleaning
Professional Storage Tank Maintenance You Can Count On
Fuel storage tank cleaning removes sludge, debris, and contaminants that compromise fuel quality and system performance. Our thorough cleaning process restores tank integrity and ensures your stored fuel meets the standards your equipment demands.
Spill Cleanup
Eco-Friendly Cleaning Solutions That Works
Petro Buster petroleum cleaner tackles oil and fuel spills with environmentally responsible cleaning power. This heavy-duty degreaser breaks down petroleum residues quickly while protecting Colorado’s environment – essential for maintaining compliance and community responsibility.
Oil Analysis
Predictive Maintenance Through Advanced Testing
Oil analysis for fleets and generators reveals engine wear, contamination levels, and maintenance needs before problems become expensive failures. Regular testing helps your operations team schedule maintenance during planned downtime instead of dealing with emergency breakdowns.
