Aurora’s Premier Engine Oil Testing and Analysis Lab

See What’s Really Happening Inside Your Engines

Engine oil analysis gives you visibility into equipment that can’t talk but definitely has stories to tell. When you get your vehicle or mission-critical equipment tested through an Engine Oil Testing & Lubrication Analysis program, you’re not just checking a box—you’re getting early warnings about wear patterns, contamination, and problems that haven’t surfaced yet.

Fleet Core’s Expertise in Engine Oil Analysis and Lubrication Health

We’ve spent years helping Aurora-area fleet operations understand what’s happening at the microscopic level in their equipment. Engine oil doesn’t just lubricate—it tells a story about heat stress, component wear, and contamination patterns that matter to your bottom line. Our team knows how to read that story, and more importantly, how to help you act on what we find.

When you work with Fleet Core, you’re tapping into regional expertise combined with industry-leading analysis capabilities. We understand the specific operational demands placed on Colorado equipment—from the altitude challenges to dust-heavy construction environments to fleet vehicles constantly moving across varied terrain. These factors shape oil degradation in ways that generic analysis might miss. That’s why our lubrication analysis goes beyond standard testing; it connects findings to your actual operational context, giving you maintenance recommendations that fit your business, not some theoretical scenario.

Who We Serve

Fuel-Dependent Operations Across Critical Industries

From construction crews managing heavy equipment to municipal fleets running 24/7 to hospitals powering critical backup systems, Aurora-area operations depend on equipment that can’t fail. Engine oil analysis testing in Aurora serves businesses where reliability isn’t optional—it’s the foundation of operational continuity. We work with organizations that understand that knowing your equipment’s health isn’t a luxury; it’s a requirement.

On-site fuel delivery

Fuel Delivery

Keep Operations Running Without Refueling Delays or Downtime

Equipment can’t perform well on an empty tank, and your oil analysis can’t tell a good story if your vehicles keep shutting down waiting for fuel. Fleet Core’s On-Site Fuel Services deliver diesel and gasoline directly to your Aurora location, whether that’s a construction site, fleet hub, or critical facility. We schedule around your operations, not the other way around.

Diesel Fuel Testing

Verify Quality  Before Problems Develop

Diesel Fuel Testing catches contamination, water content, and degradation issues that can’t be seen with the naked eye. Think of it as an oil analysis for your fuel supply—it gives you early warnings about quality problems and helps you make informed decisions about fuel storage, additives, and maintenance schedules.

Fuel Polishing near Denver CO

Fuel Polishing

Restore Fuel Quality & Safeguard Equipment Performance

Contaminated fuel creates a cascade of problems, from fuel injector clogs to engine deposits that accelerate wear visible in your oil analysis. Our Fuel Polishing service removes water, sludge, and microbial growth from stored fuel, ensuring that what flows into your equipment is clean and stable. It’s preventative maintenance that saves you from discoveries you don’t want to make.

Fuel Storage Tank Clenaing

Eliminate Sludge and Contamination From Your Fuel Storage Systems

Fuel Storage Tank Cleaning removes the accumulated sludge, water, and microbial growth that settles in tanks over time. Clean tanks mean cleaner fuel, which directly impacts equipment performance and extends the life of your pumps, filters, and injectors. When your oil analysis shows contamination trends, tank cleaning is often the root-cause solution.

Engine Oil Testing & Analysis

Lubrication Analsys to Give You Insight Into the Health of Your Engine

Engine Oil Testing & Lubrication Analysis reveals wear patterns, contamination, and component degradation before they become catastrophic failures. Your oil knows what’s happening—metal particles tell you about bearing wear, water content signals seal problems, and viscosity changes show thermal stress. We interpret that data and give you the insights you need to make maintenance decisions with confidence. Regular oil analysis turns expensive surprises into manageable, planned maintenance events.
