Fleet Fuel Cards for Trucking Operations: A Complete Buyer’s Guide

By Michael Nielsen, Editor & Publisher | 15+ Years in Diesel Repair & Fleet Operations

Last Updated: June 2026

Fleet fuel cards are the highest-leverage cost reduction tool available to any trucking operation — and one of the most consistently underutilized. Fuel represents 25-35% of total fleet operating costs, and the difference between a poor fuel card and the right one can amount to $2,000-$5,000 per truck per year in direct savings from per-gallon discounts alone. Add fraud prevention, automated IFTA reporting, and real-time purchase controls, and the right fuel card program becomes a financial management tool that pays for itself in the first month. The problem is that fuel card marketing is aggressive and often misleading — headline discount numbers rarely reflect what your fleet actually saves after fees, volume requirements, and network limitations are factored in.

This guide evaluates five fuel card programs that consistently appear on shortlists for owner-operators, independent diesel repair shops managing service vehicles, and small-to-mid-size trucking fleets: Comdata, EFS, WEX, AtoB, and Mudflap. Each is assessed across five criteria that directly affect how much your operation actually saves — not what the marketing materials promise.

What to Evaluate When Choosing a Fleet Fuel Card

Fuel card selection decisions are frequently made based on which sales representative called last or which card another driver recommended. Both are poor evaluation methods. The factors that determine actual savings are specific to your routes, your fueling patterns, and your fleet size — and they vary enough between programs that the wrong card for your operation can cost more in fees than it saves in discounts.

Acceptance Network Aligned With Your Routes

Total accepted locations nationally is a marketing number. What matters is whether the card delivers discounts at the specific truck stops and fuel stations on your actual routes. A card accepted at 95% of US fuel stations sounds universal — but if the discount only applies within a specific savings network that doesn't include the stations your drivers use, you're paying card fees for retail prices. Before evaluating any card, map your three most common routes and check each card's station locator for discount-eligible locations along those corridors.

Net Savings — Discount Minus All Fees

Net savings is the only discount figure that matters — and it requires calculating discount value against all fees: monthly card fees per card, transaction fees per purchase, application fees, and any minimum volume requirements that trigger fee penalties for lower-volume months. A $0.15/gallon discount sounds strong. On a single truck burning 1,000 gallons per month, that's $150 in monthly savings. Against a $25/month card fee plus $0.50 per transaction on 15 fill-ups, net savings drop to $110. Against a zero-fee card with a $0.08/gallon discount, net savings are $80 — and the zero-fee card wins if you miss a month's volume target and lose the higher-tier discount. Do this math with your actual numbers before applying.

Purchase Controls and Fraud Prevention

Fuel card fraud accounts for up to 22% of fleet fuel expenses at operations without proper controls — and the controls available on a card matter as much as the discount rate. Driver PIN requirements prevent unauthorized use. Fuel-only purchase restrictions eliminate non-fuel purchases on fuel cards. Daily gallon limits prevent excessive purchases. Time-of-day and day-of-week windows flag out-of-schedule fueling. Geographic restrictions alert on cards used outside expected operating areas. The best programs let you set these controls at the individual card level — per driver, per vehicle — rather than only at the account level. Evaluate control granularity during the application process, not after a fraud incident.

IFTA Reporting and Integration Capability

IFTA fuel tax reporting is a quarterly administrative burden for every carrier subject to it. Fuel cards that capture Level 3 transaction data — driver ID, vehicle ID, odometer reading, gallons purchased, fuel type, date, time, and location — automate a significant portion of IFTA data collection. Cards that also integrate with your fleet management platform or factoring company eliminate duplicate data entry entirely. Evaluate IFTA data quality and export format before choosing a card — not all programs capture the data fields required for accurate IFTA filing.

Factoring Company Compatibility

Many owner-operators and small fleets use freight factoring companies to manage cash flow — and the factoring company's preferred fuel card partner can significantly affect which card delivers the best combined financial package. Some factoring companies offer deeply discounted or free fuel cards (EFS through RTS Financial, for example) as part of their services. Choosing a fuel card independently of your factoring relationship may mean passing up meaningful savings or losing administrative integration that simplifies cash flow management. Ask your factoring company which fuel card they work with before making an independent selection.

Comdata

Profile last verified: June 2026 against comdata.com

Comdata is the OTR trucking industry's fuel card standard — and that position is earned through the mechanism that matters most for long-haul fleets: cash price access at major truck stops. Most fuel cards pay the credit price at the pump, which is typically 5-15¢ per gallon higher than the cash price. Comdata's commercial agreements with major truck stop chains give cardholders access to the cash price rather than the credit price — and stack additional per-gallon discounts on top of that baseline, delivering total savings of $0.10 to $0.25 per gallon at in-network locations for fleets with meaningful monthly volume. For a fleet that burns 5,000 gallons per month, that difference translates to $500-$1,250 in monthly savings versus a standard retail card.

Strengths

Comdata's cash price access at major truck stop chains is its single most significant competitive advantage — a savings mechanism unavailable on most competing fuel card programs.

• Cash price access at major truck stop chains (Pilot Flying J, Love's, TA/Petro, Wilco) — typically 5-15¢/gallon savings before additional per-gallon discounts are applied.
• Per-gallon discounts of $0.05 to $0.25 depending on monthly volume — higher-volume fleets unlock better rates through negotiated agreements.
• 15,000+ accepted locations across the US truck stop network — among the widest truck-stop-specific coverage of any card in this comparison.
• Comcheck payment system for non-fuel driver expenses (lumper fees, repairs, permits) — eliminates the need for drivers to carry cash or personal cards for road expenses.
• Granular purchase controls: driver PIN, fuel-only restrictions, per-transaction gallon limits, time-of-day windows, and vehicle-level restrictions.
• Level 3 transaction data capture for automated IFTA reporting — gallons, fuel type, state, driver ID, vehicle ID, and odometer in every transaction record.
• Integration with most major freight factoring companies and TMS platforms.
• Tiered plans available — basic card access through full fleet management features as operations grow.

Considerations

Comdata's fee structure requires careful review — monthly fees of $10-$25 per card and per-transaction fees on some plan types can offset discount value for low-volume single-truck operations. Always request a written fee schedule and calculate net savings at your actual monthly gallon volume before applying. The cash price advantage applies specifically at truck stop chain locations; retail gas station coverage is more limited, making Comdata a stronger fit for OTR operations than for local or mixed-route fleets that fuel primarily at retail stations.

Best Fit: OTR trucking operations from 2 to 500+ trucks that run interstate routes and fuel primarily at the major chain truck stops. Fleets where the cash price access mechanism delivers meaningful monthly savings at actual route volumes. Operations using freight factoring that can pair the card with their factoring company's preferred program for additional benefits.

EFS (Electronic Funds Source)

Profile last verified: June 2026 against wexinc.com/efs

EFS (Electronic Funds Source), now part of the WEX family of companies, built its reputation as the preferred fuel card for owner-operators and independent trucking companies through a combination of the widest truck stop discount network in the industry — 15,000+ locations — and deep integration with virtually every freight factoring company in the US market. For operators who use factoring as their primary cash flow tool, EFS frequently comes bundled through the factoring relationship at reduced or zero cost, making it the default card for a large segment of independent operators without requiring a separate evaluation.

Strengths

EFS's integration with the freight factoring ecosystem is its most distinctive competitive advantage — for factoring clients, the card often arrives at no additional cost with seamless cash advance and settlement integration.

• 15,000+ accepted truck stop locations — the widest discount network in this comparison by location count.
• Per-gallon discounts of $0.05 to $0.15 at in-network truck stops — consistent savings accessible at entry-level volumes.
• Integration with virtually every major freight factoring company in the US — often available free or at reduced cost through factoring relationships (RTS Financial, OTR Capital, and others).
• Cash advance capability for drivers on the road — a meaningful operational benefit for owner-operators managing road expenses without personal credit card exposure.
• Driver PIN, purchase type restrictions, and per-transaction controls available at the card level.
• Level 3 transaction data for IFTA reporting — fuel type, gallons, state, driver, and vehicle data captured per transaction.
• Available at $0 monthly fee through many factoring company partnerships — lowest effective cost of any program in this comparison for factoring clients.
• Accepted at all major truck stop chains including Pilot Flying J, Love's, TA, Petro, and independent stops across the network.

Considerations

EFS's per-gallon discount rates are consistent but not the deepest available at truck stop chains — Comdata's cash price access mechanism can deliver better per-gallon economics for high-volume OTR operators. For fleets not using factoring, EFS's standalone card terms and fees require the same careful net-savings calculation as any other program. Retail gas station coverage is more limited than WEX's broad network, making EFS a stronger fit for OTR routes than local delivery operations.

Best Fit: Owner-operators and small trucking fleets using freight factoring — the EFS card through a factoring partner is frequently the most cost-effective fuel card available to independent operators. Also strong for operations that value the widest truck stop network count combined with cash advance capability for road expenses.

WEX

Profile last verified: June 2026 against wexinc.com

WEX powers more than 50 fleet card programs and is accepted at 95% of US fuel stations and 45,000+ service locations — making it the universal acceptance standard in the fleet card industry. Its ClearView analytics platform captures Level 3 transaction data across every vehicle and driver, delivering the most comprehensive fuel spend visibility of any card in this comparison. For fleet managers running mixed operations where truck drivers, service technicians, and light vehicle operators all need fuel access, WEX's single-card program eliminates the operational complexity of managing multiple fuel card programs for different vehicle categories.

Strengths

WEX's universal acceptance network is its clearest competitive advantage — no other card in this comparison gives drivers more flexibility in where they can fuel without detours or network limitations.

• Accepted at 95% of US fuel stations and 45,000+ service locations — the broadest fueling network of any card in this comparison.
• ClearView analytics platform with Level 3 data capture across all transactions — industry-leading spend visibility for fleet managers.
• WEX Cross Roads card bridges truck stops and retail stations — accepted at Pilot, Love's, TA, and Flying J alongside retail gas stations.
• Per-gallon discounts of $0.03 to $0.15 within the WEX Nationwide Savings Network — strongest at in-network locations.
• DriverDash, WEX Connect, and Fleet SmartHub mobile apps for driver fueling, station discovery, and fleet management.
• 24/7 US-based customer service — meaningful for operations with drivers fueling around the clock.
• EV charging network integration through WEX EV En Route — relevant for mixed fleets transitioning toward electric vehicles.
• Two-factor authentication, spending limits, and geographic restriction controls across the card program.

Considerations

WEX's per-gallon savings are notably weaker than Comdata or EFS for pure OTR trucking operations. The best discounts ($0.15/gallon) are limited to high-volume in-network locations; outside the savings network, per-gallon discounts drop to $0.01-$0.03. For single-truck owner-operators or small OTR fleets where truck stop chain discounts are the primary value driver, Comdata or EFS will typically deliver better net savings. WEX's fee structure has also generated documented criticism — since 2022, WEX has required personal guarantees on many small business accounts, tying owner assets to the fleet's card debt. Review the personal guarantee provision before applying.

Best Fit: Larger mixed fleets managing trucks, vans, and service vehicles that need a single program with enterprise analytics and universal acceptance. Fleet managers who prioritize spend visibility and program consolidation over maximizing per-gallon savings at truck stop chains. Operations with drivers who fuel at diverse locations including retail stations where OTR-focused cards have limited coverage.

AtoB

Profile last verified: June 2026 against atob.com

AtoB is a fintech entrant that has grown rapidly in the owner-operator and small fleet segment by removing the two most common barriers to entry in fuel card programs: monthly fees and credit requirements. The card runs on the Mastercard network with nationwide acceptance, charges no monthly fees, and requires no personal credit check — making it accessible to new CDL holders, operators building business credit, and small fleets the traditional programs have historically underserved. Its Optimal Station Selection tool routes drivers to the lowest-price in-network stop on their path before they fuel, adding a behavioral savings layer on top of the card discount that compounds over thousands of annual fill-ups.

Strengths

AtoB's no-fee, no-credit-check model removes the two structural barriers that have locked small operators out of meaningful fuel card savings — and the station optimization tool delivers savings that legacy programs don't offer.

• No monthly card fees, no setup fees — zero cost structure means savings begin immediately without volume thresholds to break even on fees.
• No personal credit check required — approval based on business account structure, accessible to new authorities and operators building credit.
• Nationwide Mastercard acceptance with deepest discounts at in-network truck stops — up to $0.45/gallon at select locations, with broader coverage at standard Mastercard network rates.
• Optimal Station Selection tool routes drivers to the lowest-price in-network AtoB station on their path before fueling — a real-time behavioral savings layer unavailable on legacy programs.
• Real-time spending controls via mobile app: per-driver limits, fuel-only restrictions, geographic alerts, and instant transaction notifications.
• Average reported customer savings of $0.46/gallon combining card discounts, fraud prevention, and station optimization — a total-savings framing more honest than a headline discount number alone.
• QuickBooks integration and IFTA-compatible state-by-state transaction exports.

Considerations

AtoB's published $0.46/gallon average savings figure combines multiple mechanisms — network discounts, fraud prevention estimates, and behavioral optimization — into a single number that should be evaluated carefully against your specific route pattern and fueling behavior. The deepest per-gallon discounts are available at AtoB's in-network truck stop locations; out-of-network Mastercard transactions receive standard rates meaningfully below that figure. As a fintech entrant, AtoB's account management infrastructure is less established than Comdata's or WEX's decades-old support teams, and verified user reviews note responsiveness gaps during dispute resolution compared to legacy providers.

Best Fit: New owner-operators, small fleets (1–15 trucks), and growing operations that want meaningful fuel savings from day one without monthly fees or credit barriers. The Optimal Station Selection tool makes AtoB particularly valuable for routes where the lowest-price station changes dynamically — high-competition fuel corridors with multiple truck stops within short distances of each other.

Mudflap

Profile last verified: June 2026 against mudflap.com

Mudflap operates on a fundamentally different model than the other cards in this comparison. It's a Visa fleet card that negotiates discounts with independent and regional truck stops by offering those stops increased volume — and passes the savings to drivers at $0.25 or more per gallon at participating locations with no monthly fees, no transaction fees, and no credit check required. The trade-off is a network of approximately 700 locations focused on independent stops rather than the major chains, which limits its utility as a standalone primary card. As a zero-cost supplemental card used when a route passes an in-network location, Mudflap consistently delivers the deepest per-gallon discounts available at those stops.

Strengths

Mudflap's zero-fee structure and the depth of its per-gallon discounts at independent truck stops are unmatched by any program in this comparison — when an in-network location is on your route, the savings are significant and cost nothing to access.

• $0 monthly fee, $0 transaction fees — zero cost to carry the card and use it when a participating location is convenient.
• No credit check required — accessible to new operators and owner-operators without established business credit.
• Per-gallon discounts of $0.25 or more at participating independent truck stops — often the deepest single-location discount available anywhere in the fuel card market.
• App-based operation — drivers find nearby participating locations and activate discounts through the Mudflap app at the pump.
• Visa acceptance means backup use at retail locations when not at a participating stop.
• No commitment — carry it alongside your primary card and use it when convenient without any ongoing obligation.

Considerations

Mudflap's network of approximately 700 locations is limited to independent and regional truck stops — it is not accepted at Pilot Flying J, Love's, TA, Petro, or other major chains. This makes it unviable as a standalone primary fuel card for most OTR operators whose routes go through chain truck stops for amenities, showers, and driver services alongside fuel. Fleet management tools are minimal — limited controls, basic reporting, and no IFTA automation make it unsuitable as the only card for a fleet that needs spend visibility and compliance data.

Best Fit: Owner-operators and small fleets using Mudflap as a supplemental card alongside a primary Comdata or EFS program — adding it costs nothing and the incremental savings at participating independent stops compound meaningfully over a year. Also the best starting point for new authorities and operators without business credit who need a zero-commitment fuel card while building their primary program.

Quick Comparison: Fleet Fuel Cards for Trucking Operations

How to Choose the Right Fleet Fuel Card

What Are Your Actual Routes and Fueling Locations?

Route analysis is the foundation of any fuel card evaluation. Before comparing programs, map your three most common routes and identify where your drivers actually fuel — which chains, which independent stops, and how often drivers end up at retail gas stations versus truck stops. Then check each card's station locator for discount-eligible locations along those specific corridors. A card that covers 15,000 locations nationally but misses your three primary fueling stops is worth less than a card with 3,000 locations that hits all of them.

What Is Your Monthly Gallon Volume Per Vehicle?

Net savings calculations are volume-dependent. Calculate your average monthly gallon consumption per truck, then run the net savings math for each card you're evaluating: monthly discount value (gallons × per-gallon rate) minus monthly fees (card fee + estimated transaction fees). Do this at your actual volume, not the volume required to unlock the headline discount tier. Some programs require 5,000+ gallons per month to access their best rate — a threshold most single-truck operators never reach.

Do You Use a Freight Factoring Company?

Ask your factoring company which fuel card they partner with before evaluating programs independently. Many factoring companies offer EFS or similar fuel cards through their program at zero additional cost — and some provide fuel advances that effectively give you access to fuel savings before your invoice is paid. Choosing a card independently of your factoring relationship may mean paying for a program that your factoring company would have provided free, or losing IFTA and cash flow integration that simplifies your administrative burden.

What Controls Do You Need Per Driver and Per Vehicle?

Evaluate control granularity before evaluating discount rates — unauthorized fuel purchases eliminate savings faster than any per-gallon discount creates them. Ask specifically whether controls can be set at the individual card level (per driver, per vehicle) rather than only at the account level. Verify that the program supports fuel-only restrictions, daily gallon limits, time-of-day windows, and driver PIN requirements. Get confirmation of control capabilities in writing — not during a sales call.

Does a Two-Card Strategy Beat a Single Program?

Many experienced operators save more with two cards than with any single program. The standard combination is a primary OTR card (Comdata or EFS) for chain truck stops and Mudflap for independent stops with deeper discounts. Since Mudflap carries zero fees, adding it to an existing primary card program costs nothing and adds savings at every in-network independent stop. Calculate whether a two-card strategy produces better annual net savings than upgrading to a higher tier of your primary card before committing to a single program.

What Does the Fee Schedule Say in Writing?

Request a written, line-item fee schedule from every program before applying. Monthly card fees, per-transaction fees, minimum volume penalties, application fees, and late payment charges all affect net savings — and programs that decline to provide written fee schedules before application are telling you something important. Never calculate expected savings from the marketing materials alone. Fuel card programs are highly competitive and marketing language frequently overstates savings by citing best-case rates that require volume thresholds most independent operators don't reach.

Frequently Asked Questions

What is the best fuel card for trucking companies?

HDJ gives dual Top Pick ratings based on different primary use cases. Comdata earns HDJ Top Pick for OTR trucking fleets that primarily fuel at major truck stop chains — the cash price access mechanism delivers the best per-gallon economics for high-volume operators. EFS earns HDJ Top Pick for owner-operators and factoring-integrated fleets — the combination of a 15,000+ location network and frequent zero-cost availability through factoring partnerships makes it the default best-value card for independent operators. WEX and AtoB both earn Strong Contender status for mixed fleets and no-fee entry respectively. The best card for your operation depends on your routes, volume, and whether you use freight factoring.

What fuel card saves the most money for owner-operators?

Net savings — discount minus all fees — varies by monthly gallon volume and route. For owner-operators using freight factoring, EFS through a factoring company frequently delivers the best net savings because the card comes at no additional cost. For owner-operators not using factoring, AtoB's no-fee structure eliminates the break-even problem entirely, while Comdata's cash price access delivers better per-gallon economics at truck stop chains for operators burning 1,000+ gallons per month. Adding Mudflap as a zero-cost supplemental card for independent truck stops consistently improves total savings regardless of which primary card you carry.

What should I look for when evaluating a fleet fuel card?

Route analysis first — verify discount-eligible locations along your actual corridors, not nationally. Then calculate net savings at your actual monthly gallon volume (discount value minus all fees). Evaluate control granularity — driver PIN, fuel-only restrictions, and per-card limits. Check IFTA data capture if you're subject to IFTA filing. Ask your factoring company for their preferred card before evaluating independently. Request a written fee schedule before applying to any program.

How much can a fuel card save a trucking company?

Savings range from $2,000-$5,000 per truck per year for active OTR operators through a combination of per-gallon discounts, fraud prevention, and IFTA automation savings. For a 50-truck fleet, the difference between a 3¢/gallon program and a 15¢/gallon program at 1,500 gallons per truck per month equals $72,000 annually before fees. Actual savings depend on monthly gallon volume, the specific discount rate your operation qualifies for, and the fee structure of the program you choose.

Can I use more than one fuel card?

Yes — and many operators save more with two cards than with any single program. The most common strategy pairs a primary OTR card (Comdata or EFS) for chain truck stop coverage with Mudflap for independent truck stop savings. Since Mudflap carries zero fees, adding it costs nothing and improves total savings on every fill-up at a participating independent stop. Some operators also pair AtoB for its station optimization and no-fee structure on general routes with a chain-specialist card for OTR corridors.

What is the difference between Comdata and EFS?

Both Comdata and EFS are accepted at the major OTR truck stop chains and deliver meaningful per-gallon savings. The key differences are in their discount mechanisms and fee structures. Comdata's cash price access at chain truck stops can deliver better per-gallon savings for high-volume fleets — the mechanism differs from EFS's standard discount structure. EFS is available through most freight factoring companies at zero additional cost, which often makes it the more economical choice for factoring clients regardless of the per-gallon rate comparison. The real decision often depends on which card your factoring company supports.

Is Mudflap worth it for owner-operators?

As a supplemental card alongside a primary OTR program, yes — unconditionally. Mudflap costs nothing to carry and delivers $0.25 or more per gallon at participating independent truck stops. For a driver who fills up at an in-network stop twice a month with 200-gallon fills, that's $100 in savings per month at zero card cost. As a standalone primary card, Mudflap's network is insufficient for most OTR operations that need chain truck stop access and IFTA reporting.

The Bottom Line

Fuel cards are the highest-ROI cost reduction tool in fleet management — and the evaluation doesn't require months of analysis. Map your routes, calculate your monthly gallon volume, check discount-eligible locations along your corridors, and run the net savings math with your real numbers. That sequence produces a defensible decision in an afternoon.

For most OTR trucking operations in HDJ's audience, the evaluation starts with Comdata for chain truck stop savings and EFS for factoring-integrated operations — both earn HDJ Top Pick for different but equally valid reasons. WEX is the right choice when universal acceptance and enterprise analytics matter more than maximizing per-gallon savings at truck stops. AtoB fills the no-fee, no-credit-check gap for new operators and small fleets who deserve access to meaningful fuel savings from day one. Mudflap belongs in every owner-operator's wallet as a zero-cost supplemental card regardless of which primary program you carry.

Ask your factoring company first. Map your routes second. Calculate net savings at your actual volume third. Then apply. The savings start compounding on your first fill-up.
