Is a fuel card worth it for a single truck?

Often yes, but only if the fee math clears. A prepaid card with $0 monthly fees (like TCS's published structure) is worth it from the first in-network gallon. A card with monthly or per-card fees needs volume: divide the total monthly fees by the realistic per-gallon discount to find your break-even gallons, and compare that to what you actually pump. FuelHere's savings calculator does this in seconds.

Do fuel cards check credit?

It depends on the model. Credit-line cards (WEX, Comdata, RTS's standard card, AtoB Flex) generally underwrite the business. Prepaid and funded-account models (TCS, AtoB Unlimited, RTS's self-funded version) and free discount apps (Mudflap) advertise no credit check — that's why they're popular with new authorities.

Why do advertised discounts differ so much from what I actually save?

Advertised figures are usually ceilings or issuer-selected averages (for example, AtoB's 42¢ figure is its H2 2025 average, TCS's 59¢ is its Q2 2026 average). Your realized discount depends on which stations you use, your volume tier, fuel grade, and — for some cards like Comdata — paying on time. Model your own lanes before believing any single number.

Which fuel card has no monthly fee?

As published in July 2026: TCS advertises $0 monthly/annual fees, the Mudflap app is free, and RTS is commonly reported as no-monthly-fee (not published — confirm). Most other cards charge per card or per account monthly. Always net fees against the discount on your real gallons.

Does FuelHere get paid by any of these card companies?

No. FuelHere does not accept placement fees from fuel-card providers, and there are no affiliate links on this page. If that ever changes for a specific card, we'll disclose it on that review itself. See our methodology page for how these evaluations work.

Best fuel cards for owner-operators (2026)

For most single-truck diesel operators, a zero-fee prepaid card (TCS) or a low-fee flexible card (AtoB) beats the legacy fleet cards — and the free Mudflap app is worth stacking regardless. Retail-network cards like WEX, Fuelman, and Coast fit service fleets, not OTR trucking. The right answer depends on your lanes and gallons, so test every card below against your own numbers.

Card by card: who each one actually fits

TCS Fuel Card

Network: 2,300+ in-network locations (TA, Petro, TA Express, AMBEST, Casey's, Kwik Trip, Maverik, Sapp Bros, Road Ranger); accepted at 12,000+ locations at cash price.
Choose it when: You're a new authority or single-truck operator who can prepay, runs lanes with TA/Petro or AMBEST coverage, and wants zero fixed fees.
Skip it when: You need a credit line for cash-flow, or your lanes are dominated by Pilot/Love's.

Test this card's published numbers on your gallons

AtoB (Flex / Unlimited)

Network: Issuer claims 60,000+ discount locations including major truck stops.
Choose it when: You want a modern card that works for mixed vehicles (diesel + unleaded), app-based controls, and either credit or instant-approval prepaid.
Skip it when: You're fee-averse at very low volume — the setup and per-card fees need gallons to earn back.

Mudflap (app + card)

Network: 3,600+ in-network truck stops (TA/Petro, Speedway, Kwik Trip, Sapp Bros, Casey's, Maverik, Road Ranger, 7-Eleven); the card is accepted more broadly.
Choose it when: You want discounts with zero commitment — the app costs nothing to try alongside whatever you already use.
Skip it when: Your lanes live on Pilot/Flying J or Love's, which are outside the discount network (network changes — check the app).

Run your gallons through the savings calculator

RTS Fuel Card

Network: ~12,000 truck stops accepted; Pilot Flying J is a named partner.
Choose it when: You run Pilot-heavy lanes or already factor with RTS Financial (the card is commonly bundled).
Skip it when: You want every fee published up front before talking to sales.

Test this card's published numbers on your gallons

Comdata (small-fleet tiers)

Network: TA/Petro anchored, plus Pilot and Love's participation by tier.
Choose it when: You fuel TA/Petro-first and will reliably pay on time (the discounts are conditioned on it).
Skip it when: You occasionally pay late — reported penalty schedules are steep, and the discounts vanish.

Test this card's published numbers on your gallons

EFS / Fleet One EDGE (WEX OTR)

Network: 4,000–4,500+ in-network sites; accepted at 12,000+ truck stops.
Choose it when: You're a growing fleet that can negotiate, and you want fleet-check/MoneyCode cash features drivers know.
Skip it when: You're a single truck without negotiating leverage — the published tiers start small at low volume.

Run your gallons through the savings calculator

RoadFlex

Network: Visa acceptance (broad), with discounts concentrated at partner merchants.
Choose it when: You run a mixed fleet (trucking + construction/service vehicles) and want one Visa-accepted card.
Skip it when: You expect truck-stop diesel spreads — reports note truck stops may settle at credit price, offsetting small discounts.

Run your gallons through the savings calculator

WEX Fleet Card

Network: Accepted at ~95% of U.S. gas stations — retail-focused, not truck-stop-focused.
Choose it when: You run local/regional service vehicles fueling at retail gas stations, and controls/reporting matter more than diesel spreads.
Skip it when: You're an OTR diesel operator — the big truck-stop chains are excluded from rebates.

Run your gallons through the savings calculator

Coast

Network: Retail gas stations (Exxon, Mobil, 7-Eleven, Circle K, Casey's, Shell) — not truck-stop diesel.
Choose it when: You run a field-service or vocational fleet on gasoline and want clean per-user pricing and modern controls.
Skip it when: You buy truck-stop diesel — this card isn't built for OTR.

Run your gallons through the savings calculator

Fuelman

Network: Large retail network; extended network via Mastercard.
Choose it when: You're a local/regional small-business fleet with steady volume that clears the subscription cost.
Skip it when: You're a single truck — a fixed $39+/mo needs a lot of gallons to pay back.

Who should skip a fuel card entirely

If you pump only a few hundred gallons a month at retail gas stations, a flat cash-back credit card can beat a fuel card once monthly fees and network restrictions are netted out — and it never locks you to a station map. The break-even is pure arithmetic: monthly card fees divided by realistic cents-per-gallon savings equals the gallons you must pump before the card earns a dollar. Run it in the fuel card savings calculator — it models discount, cashback, and no-card scenarios side by side.
