CFN Fuel Card Review: Pricing, Controls, and Who It’s Best For

California retail diesel is pushing close to $7 per gallon in 2026, according to recent EIA fuel price data. Meanwhile, wholesale costs at the rack sit well below that. For West Coast fleets, the gap between what you pay at the pump and what the fuel actually costs has never been wider. That gap is exactly where the CFN fuel card operates.

The CFN card connects fleets to over 3,000 cardlock locations with wholesale-based pricing, plus purchase controls that most retail fuel cards can’t match. But it’s not the right card for every fleet, and some of its tools haven’t kept up with the competition. In this CFN fuel card review, we’ll cover how pricing works, what controls the card offers, where it falls short, and who should (and shouldn’t) apply.

CFN stands for the Commercial Fueling Network. It was founded in 1988 and is now owned by Corpay (formerly Fleetcor). Unlike a typical fuel card company, CFN operates through a network of over 200 independent oil companies called “marketers.” These marketers own and operate CFN cardlock fuel stations, issue CFN fuel cards, and handle customer pricing, billing, and support.

Your marketer is the company you actually work with day to day. The fees you pay, the customer service you get, and the tools available to you all depend on which marketer you sign up with. Think of it like the Visa model: Visa provides the payment network, but your bank sets the terms.

The CFN fuel card is accepted at roughly 2,500 cardlock locations and over 65,000 retail gas stations and truck stops nationwide through the FleetWide program. If you want to understand how cardlock fueling works and why it’s different from retail, it’s worth reading up on the basics before evaluating the card.

CFN uses a cost-plus pricing model at cardlock locations, and this is the card’s single biggest advantage.

Instead of paying whatever price is posted on the pump (like you would at a retail gas station), your price is built from the wholesale rack cost reported by OPIS (Oil Price Information Service). OPIS publishes daily wholesale rack prices by region, and those prices serve as the cost foundation for nearly every gallon of fuel sold in the U.S.

OPIS rack price + freight cost to the station + a fixed site interchange rate (paid to the station owner) + your marketer’s margin + applicable fuel taxes.

The result is a price that typically runs 10 to 35 cents per gallon below retail, depending on your market. In states like California, Oregon, and Washington, where retail margins are widest, that spread can reach 30 to 60 cents per gallon or more during price spikes.

One recent industry analysis noted California diesel averaging nearly $6.94 per gallon at retail, while the wholesale-to-retail gap continues to widen.

CFN prices update daily at 3pm PST, so a transaction before that time is priced after the update. Prices are not posted at the pump, which is standard for cost-plus networks but can feel unfamiliar if you’re used to seeing a number before you fuel.

And at FleetWide retail locations (gas stations and truck stops outside the cardlock network), you pay the posted pump price with no wholesale discount. The savings are at cardlock stations. You can check current CFN prices in your area to see what fleets near you are paying right now.

There are 2,500 cardlock stations, and the CFN cardlock network is concentrated in seven western states:

In those states, CFN stations are common along major highways, in metro areas, and in industrial zones. In some western metros, CFN cardlocks significantly outnumber traditional truck stops. That density matters because the more often your drivers fuel at cardlock stations instead of retail, the more you benefit from cost-plus pricing.

The FleetWide program extends acceptance to over 65,000 retail gas stations and truck stops nationwide, including brands like Chevron, Pilot, and Love’s. This gives drivers a backup option when they’re outside cardlock territory. Just keep in mind that retail transactions don’t receive cost-plus pricing.

Coverage weakens once you get east of the Rockies. If your fleet runs nationwide or is based in the Southeast or Midwest, you’ll find yourself using the retail network more often than the cardlock network, which chips away at the pricing advantage. One third-party review put it bluntly: savings are marginal or nonexistent in low-margin markets like Texas, where retail and wholesale prices run closer together. CFN is fundamentally a West Coast card.

This is where CFN separates itself from most fuel cards on the market. The standout feature is product controls, which let you restrict purchases by fuel type. If your vehicles run diesel, you can set a diesel-only restriction, and the pump at a CFN cardlock station will physically decline a gasoline transaction. The pump won’t activate.

That eliminates the possibility of drivers fueling personal vehicles on the company card or accidentally filling a diesel truck with unleaded.

As one CFN marketer explains, CFN also ties purchase limits to gallons rather than dollars. Dollar-based limits have to be adjusted constantly as fuel prices change. Gallon limits stay consistent regardless of market fluctuations, which means your drivers can always fill up completely without hitting a cap that was set when diesel was 40 cents cheaper.

Beyond product controls and gallon limits, the CFN card offers:

You can also lock individual cards to CFN cardlock locations only, blocking retail access entirely to guarantee every transaction gets cost-plus pricing.

Product controls are only enforced at CFN cardlock stations. Retail gas stations and truck stops don’t have the point-of-sale configuration to support fuel type restrictions. When drivers use retail locations, you’ll get an exception alert email if they purchase the wrong product, but the transaction won’t be declined at the pump.

CFN cards capture Level III transaction data on every purchase:

That data feeds into IFTA reporting by state and vehicle, MPG and cost-per-mile tracking, and invoicing organized by branch, department, or hub. You can export reports in Excel, which makes it straightforward to pull data into your accounting or fleet management software.

The CFN network portal itself is basic. It doesn’t display fuel pricing in transaction data until after the daily 3pm PST price update, and the interface feels dated compared to fintech competitors.

The CFN FleetWide mobile app, which drivers use to find stations, currently sits at a 2.0 out of 5 rating on the App Store with complaints about outdated location data and occasional misdirects to stations that no longer accept the card.

If a polished, modern online dashboard is a high priority for your team, this is CFN’s weakest area. That said, the portal experience varies by issuer. Some CFN marketers have invested in better tools than others, so the dashboard you get depends on who you choose.

This is where the marketer model matters most. CFN itself doesn’t set fees. Your marketer does. That means fee structures vary significantly from one provider to the next.

Some CFN card providers, including C NRG Fleet, charge zero card fees, zero transaction fees, no monthly minimums, and no contracts. Others may charge monthly card fees, per-swipe transaction fees, setup fees, or inactivity charges.

Before you sign with any CFN marketer, ask for a complete written fee schedule. If they won’t provide one, that’s a signal to keep looking. The right question isn’t “what does CFN cost?” It’s “what does my CFN provider charge?”

The CFN fuel card is a specialist tool, not a universal one. For West Coast fleets, especially in California, it offers something most fuel cards don’t: pricing that starts from wholesale instead of retail, and purchase controls that physically prevent the wrong fuel type from being pumped.

If your drivers are fueling at CFN cardlock stations regularly, the per-gallon savings add up fast, particularly in markets where retail margins run wide.

Where CFN falls short is its technology. The app and portal are behind the curve, and coverage thins out significantly outside the western states. If your fleet needs nationwide reach, a polished dashboard, or truck stop amenities, a universal card is a better fit.

If CFN sounds like it fits your operation, you can apply for a C NRG Fleet CFN card and get set up with no fees, no contracts, and cards shipped the next business day.
