Fuel Prices at Centennial Airport

Centennial Airport sells fuel through five FBOs spread across the field, and between them you can get every grade a general aviation pilot is likely to need: 100LL, Jet A, and UL94 unleaded avgas. What you will not find here, or on any airport's web page for that matter, is a reliable real-time price. Fuel prices move week to week and sometimes day to day, so this page focuses on what's available and how to shop it, not on numbers that will be stale by the time you read them.

Fuel Types at KAPA

All three common piston and turbine fuels are sold on the field. Here's the quick breakdown.

Self-Serve vs. Full-Service

Self-serve 100LL is the budget option. You pump your own gas, there's no ramp fee attached to the transaction, and you're in and out quickly if the pump is free. The tradeoff is that nobody's watching your airplane, nobody's topping off your oil, and if the pump is down or the line is long, you're on your own.

Full-service costs more per gallon, sometimes noticeably more, but you get a lineman who marshals you in, fuels the airplane while you go inside, and often handles oxygen, oil, or a quick wipe of the windscreen. For a transient pilot who wants a fast turn, or a jet that needs a specific fuel load calculated, full-service through one of the FBOs is usually the easier path. For a local pilot topping off a Cessna on a Saturday morning, self-serve often makes more sense.

The FBOs on the Field

Five FBOs handle fuel sales at Centennial: Modern Aviation, Signature North, Signature South, jetCenters of Colorado, and The Heliplex. Each sets its own pricing, and prices between them can differ by a meaningful amount on any given day, so it's worth a quick phone call or a look at a price aggregator before you assume one is cheaper than another.

Typical Price Ranges (General Context Only)

As a rough, general sense of the market: 100LL commonly runs in the mid-$5 to $7 per gallon range at Front Range reliever airports in 2026, with full-service and self-serve options often differing by a dollar or more per gallon. Jet A pricing tends to track broader fuel markets and varies by FBO and by how much volume you're buying. These are representative figures for the region, not KAPA-specific quotes, and they will drift over time.

How to Compare FBOs Without Wasting Time

If cost matters more than convenience on a given day, a few minutes of homework pays off. A live aggregator will show you a snapshot across all five FBOs at once, which beats calling each one individually if you just want a rough sense of who's cheapest that morning. If you need an exact quote, including any ramp fee or ground handling charge that might apply to your aircraft, a direct call to the FBO is still the more reliable path, since aggregator listings can lag a real-time change at the pump.

It also helps to think about the whole stop, not just the fuel. A slightly higher price per gallon at a full-service ramp can still work out cheaper overall if it saves you an hour of waiting behind other traffic at a busy self-serve pump, or if it comes bundled with a courtesy car or a quick turn that gets you back in the air sooner. None of that shows up in a per-gallon number, so weigh it against your actual schedule for the day.

What Actually Moves the Price You Pay

A posted per-gallon number is rarely the whole story. Many FBOs waive a ramp or facility fee if you buy a minimum quantity of fuel, and charge that fee separately if you don't hit the threshold. Volume matters too: an operator buying several hundred gallons for a jet is negotiating from a different position than a Cessna buying twenty gallons on a Saturday, and some FBOs quietly extend a better rate to based customers or fuel-account holders than they quote to transient walk-ins. None of that shows up in a single number on an aggregator screen, which is one more reason a direct phone call beats guessing when the dollar amount involved is significant.

Matching Your Stop to the Right Fuel Option

The self-serve versus full-service call isn't really about which one is objectively better. It depends on what you're flying and why you're on the ramp that day. A rough way to sort it:

• If you're a local pilot topping off a trainer or a personal piston airplane on a routine day, self-serve 100LL is usually the right call. You save money and you're not waiting on anyone else's schedule to get back in the air.
• If you're flying a turbine aircraft that needs a specific fuel load calculated against weight and balance, go through an FBO. A lineman who fuels jets every day is less likely to misjudge an unfamiliar load than you are pumping equipment you don't use often.
• If you're a transient pilot on a tight schedule, full-service is usually worth the extra cost per gallon. Getting marshaled in, fueled, and often handed a courtesy car while you're inside saves more time than the self-serve discount is worth.
• If the self-serve pump is occupied or out of service when you taxi up, don't wait it out. Head to an FBO ramp and ask for full-service instead. The time lost standing around usually costs more than the price difference would have.

A Common Snag: Card Readers and Pump Downtime

Self-serve pumps are simple machines until they aren't. Card readers time out, receipt printers jam, and a pump that worked fine last week can end up flagged out of service with nothing posted about it except a handwritten sign taped to the housing. This is a routine nuisance at self-serve fuel islands generally, not something unique to KAPA.

The practical fix is the one experienced pilots reach for without much thought: if the pump won't take your card or the wait is longer than expected, taxi to the nearest FBO ramp and ask for full-service instead. It costs more per gallon, but it beats burning daylight troubleshooting a machine that isn't yours to fix. If you're running close to a personal fuel reserve minimum for the day, assume your first-choice option might not pan out and keep a fallback FBO in mind before you land, not after.

Bottom line: KAPA gives you a real choice of fuel type and service level across five FBOs, which is more flexibility than plenty of GA airports offer. None of that flexibility is worth much if you show up assuming a price or assuming a specific pump will be available. Treat the fuel types and service options on this page as fixed reference information, and treat the actual price as something you check same-day, every time, by phone or aggregator.
