Why Smart Businesses Get Their Fuel Tested
- Early Contamination Detection
- Regulatory Compliance Documentation
- Predictive Maintenance Planning
- Stored Fuel Longevity
Fleet Core’s Expertise in Fuel Quality Management
We’ve spent years analyzing fuel across Colorado’s Front Range, and here’s what we’ve learned: Golden’s altitude and temperature swings create unique challenges for stored diesel. That thin air? It means condensation builds up faster in your tanks. Those cold winters followed by warm spring days? Perfect conditions for microbial growth you can’t see until it’s already causing problems.
Our testing protocols go beyond basic contamination checks. We analyze fuel stability, additive effectiveness, and storage conditions specific to Golden’s environment. Whether your fuel sits in an underground tank at a hospital or in portable tanks at a construction site off Highway 6, we understand how local conditions affect fuel performance. Testing gives you the information you need to act—whether that’s scheduling polishing, adding stabilizers, or planning a full tank cleaning.
Why Choose Us
Your Fuel’s Condition Affects Everything and Fleet Core can Keep Your Fuel Clean and Ready for Use.
Clean fuel isn’t just nice to have. It is simple insurance for your fleets, generators, and equipment. We understand that Golden businesses can’t afford to have outages when the power goes out. And you can’t afford to have equipment breakdown or fleet vehicles get stranded due to contaminated fuel. We can save your company thousands of dollars in breakdown costs and lost productivity, just by ensuring your fuel is clean and ready for when you need it.
We Are the Experts that Fuel Dependent Business Trust
Fuel Delivery
On-Site Diesel When You Need It
Emergency and scheduled diesel delivery keeps your Golden operation supplied without the logistics headaches. We bring quality fuel directly to your facility, fleet yard, or job site, no matter where you’re located in the valley or up in the foothills.
Fuel Polishing
Remove Contaminants Before They Damage Equipment
Fuel polishing filters out water, sediment, and microbial growth that testing identifies as problems. It’s the difference between knowing you have an issue and actually fixing it before your equipment pays the price.
Tank Cleaning
Restore Storage System Performance
Fuel storage tank cleaning removes the sludge, sediment, and contaminated fuel that testing reveals at the bottom of your tanks. Clean tanks mean better fuel quality, fewer filter changes, and equipment that runs the way it should.
Petro-Buster
Keep it On-Hand and Be Prepared for Spills and Contamination
Petro Buster tackles fuel and oil spills quickly, breaking down petroleum residues without harsh chemicals. One spill during a fuel transfer or equipment leak can shut down operations. Our cleanup solution gets you back to work faster and cleaner.
Oil Analysis
Identify Issues BEFORE They Become Breakdowns
Oil analysis on your vehicles and mission-critical equipment catches wear patterns, contamination, and breakdown before a catastrophic failure stops your operation. It’s like having X-ray vision into what’s happening inside your engines and hydraulic systems. You see problems developing long before they become expensive repairs or unplanned downtime.
Who We Serve
Critical Operations That Need Reliable Fuel
Whether you’re coordinating a municipal fleet on Washington Avenue or managing backup power for a healthcare facility near the Colorado School of Mines, contaminated diesel creates risks you can’t accept.

Testing Turns Guesswork Into Informed Decisions
You know your equipment matters. What you might not know is whether that fuel you’ve been storing for the past eighteen months is still protecting expensive injection systems or quietly becoming corrosive enough to cause failures. Testing eliminates the uncertainty that leads to either premature maintenance spending or unexpected breakdowns. You’re making decisions based on what’s actually happening in your fuel, not assumptions about what should be happening.
The peace of mind that comes with confirmed fuel quality isn’t just emotional comfort. It’s operational confidence that lets you focus on running your business instead of worrying about fuel-related failures. When winter storms hit and your facility’s generators need to carry full building loads, you’re not crossing your fingers and hoping. You know the fuel will perform because testing proved it weeks before the emergency arrived.
