- Early Detection of Component Wear
- Contamination Identification
- Remaining Oil Life Assessment
- Cost-Justified Maintenance Decisions
Your Equipment Deserves Better Than Blind Maintenance
Here’s what most operators do, they change oil on a calendar schedule, cross their fingers, and hope nothing expensive breaks. Fleet Core takes a different approach. We’ve spent years analyzing oil samples from construction equipment battling Golden’s elevation changes, ag machinery grinding through Eastern Plains dirt, and municipal fleets navigating Colorado’s temperature swings. Our lab partnership provides detailed reports on 20+ wear metals, contamination levels, viscosity breakdown, and additive depletion.
When we test oil from your excavators, dump trucks, generators, or irrigation pumps, you’re not getting generic numbers. You’re getting Colorado-specific insights that account for how altitude affects combustion efficiency, how temperature extremes stress lubricants, and how local soil composition shows up as silicon contamination. That intelligence transforms maintenance from reactive panic into strategic planning.
Who We Serve
Operations That Can’t Afford Unexpected Equipment Failures
Golden sits at the intersection of major construction corridors, agricultural operations, and municipal infrastructure that demands reliability. Fleet Core supports operations where equipment downtime creates expensive consequences of missed project deadlines, harvest delays, and service interruptions. Our engine oil analysis in Golden helps operations shift from reactive maintenance to strategic asset management.

Why Choose Us
Protecting Golden Equipment With Lab-Quality Intelligence
Fleet Core has analyzed thousands of oil samples from Colorado operations facing the same challenges you deal with. From altitude, temperature extremes, dusty conditions, and demanding work cycles, your business experiences it all. Our testing programs help construction companies avoid mid-project breakdowns, keep municipal fleets rolling through winter emergencies, and help ag producers maximize equipment life through brutal planting and harvest seasons.
Prevent Catastrophic Failures
- Identify bearing wear before components seize
- Detect coolant leaks before head gasket replacement becomes mandatory
- Track viscosity breakdown before oil loses protective capability
Extend Equipment Service Life
- Optimize drain intervals based on actual oil condition instead of calendar guessing
- Catch contamination early when cleaning prevents damage
- Justify component replacement with hard data instead of reactive decisions
Reduce Total Operating Costs
- Avoid unnecessary oil changes when testing confirms remaining service life
- Prevent secondary damage from failed components distributing metal through systems
- Schedule repairs during planned downtime instead of emergency service rates
Data-Driven Maintenance Planning
- Trend analysis across your entire fleet reveals patterns
- Historical baselines establish normal wear rates for each asset
- Predictive scheduling prevents surprises during critical operational periods
Complete Fuel and Fluid Management Solutions
Fleet Core is your go-to source for everything fuel-related. From delivery to fuel storage maintenance, we have your back. And by getting your fuel from Fleet Core, you can bypass the markups charged by the national brokers.
Fuel Delivery
On-Site Fueling That Matches Your Schedule, Not Ours
Construction deadlines and harvest windows don’t wait for convenient fueling hours. Fleet Core delivers bulk diesel, gasoline, and DEF directly to your Golden jobsites, equipment yards, and ag operations. Get scheduled deliveries for predictable operations or emergency response when you’re running dry mid-shift.
Diesel Fuel Testing
Do You Know the Quality of Your Stored Fuel? We Can Tell You!
Not all fuel deliveries meet spec—especially when you’re buying bulk from multiple sources. Fleet Core’s fuel testing identifies contamination, water content, cetane levels, and biological growth before bad diesel destroys injection systems or gels up in your tanks during a February cold snap.
Fuel Polishing
Keep Stored Diesel Ready When Equipment Needs It
Stored fuel doesn’t stay clean forever, not in Golden’s climate. Fleet Core’s fuel polishing removes water, sludge, and microbial contamination that accumulates in diesel tanks, preventing filter clogs and injector damage when you fire up equipment after winter storage or seasonal downtime.
Fuel Storage Tank Clenaing
Remove the Sludge Stealing Your Fuel’s Performance
Diesel storage tanks accumulate water, sediment, and bacterial growth over time. Fleet Core’s tank cleaning service removes contamination from the bottom of your storage system, restoring fuel quality and preventing the distribution of sludge through your entire fuel system every time you top off equipment.
Spill Cleanup
Keep Your Rapid Response On-Hand For Accidental Spills
Hydraulic line failures and fuel tank leaks happen. Fleet Core’s Petro Buster solution breaks down petroleum contamination fast, protecting Golden’s watersheds and keeping your operation compliant. One application handles what used to require expensive disposal services and regulatory nightmares.
Engine Oil Testing & Analysis
Predictive Intelligence for Every Critical Asset
You know what’s expensive? Replacing a transmission because nobody caught the bearing wear spreading through the gears. Fleet Core’s oil analysis program tracks contamination trends across your entire fleet or equipment roster, helping you schedule maintenance when components need attention—not after catastrophic failure doubles your repair bill.
