The right fuel card is the one that produces the lowest route-level net cost after discounts, transaction charges, account fees and funding costs at the truck stops you can actually use. Compare the same lanes, gallons and fill locations; then verify the current agreement, eligibility rules, settlement timing and controls in writing. A large advertised discount or nationwide station count is not enough by itself.
Start with the price you will actually pay
A fuel card discount is useful only when it applies at a practical stop on your regular lane and survives every fee attached to the account. The number on an advertisement may be an average, a maximum, a historical result or a discount calculated against a price you do not normally pay. Your comparison should therefore begin with the account balance that would be debited for each fill, not with the headline cents-per-gallon figure.

Use this formula for each expected purchase:
Net fuel cost = gallons × (cash or posted price − applicable discount) + transaction fees + allocated account, card, setup and payment fees.

For example, if a card costs $6 per month and you expect to buy 600 gallons that month, the card charge adds 1 cent per gallon before any transaction fee. A one-time $75 setup charge can be spread over the months you reasonably expect to keep the account, but also show the first-month cost separately so a short trial is not made to look cheaper than it is.

Illustrative calculation
The following is a method example, not a market quote. Assume a 500-gallon fill at a $3.80 cash price, a $0.20-per-gallon discount, a $0.50 transaction fee and $20 of allocated monthly or setup costs. The calculation is 500 × ($3.80 − $0.20) + $0.50 + $20 = $1,820.50. If the same stop were out of network and carried a $3 transaction charge instead, the result would be $1,823.00. On a small fill, that fixed charge has a larger per-gallon effect.
Questions to ask about the benchmark
- Is the discount taken from the cash price, the posted retail price, a provider-negotiated price or another benchmark?
- Does the discount appear immediately at the pump, after the transaction is processed or as a later account credit?
- Is the offer limited to a minimum purchase, a share of your fuel volume, specific products or named locations?
- What happens when a location is outside the network, temporarily offline or unable to process the card?
- Are taxes, cash advances, reefer fuel, DEF or other purchases treated differently?
Ask for a written answer and retain the current fee schedule and card agreement. Terms can change, and the public description of a program may not contain every charge.
Match the network to your real lanes
Station-count claims matter only if the locations are reachable with your equipment, open when you arrive and priced competitively on the lanes you actually run. Map several weeks of normal trips and mark the places where you can safely park, maneuver, buy the required fuel and remain within hours-of-service constraints. Then check each provider’s current location finder or app against that list.

In-network pricing and fees can differ sharply from out-of-network transactions. A card that saves more at a preferred stop may be worse if your route routinely forces you to leave the network and pay a fixed fee. Include at least one normal fill, one backup fill and one likely out-of-network fill in your comparison.
What the documented networks show
- TCS Fuel: TCS says its card is accepted at more than 12,000 fuel locations and that more than 2,300 in-network locations have no fuel transaction fee. Its FAQ lists examples including TA, Petro, TA Express, AMBEST, 7FLEET Diesel Network, Casey’s, Kwik Trip/Kwik Star, Sapp Bros and Road Ranger. TCS says out-of-network transaction fees may apply and vary by location. Check the current location finder rather than assuming every station under a listed brand qualifies. See the TCS owner-operator page and TCS FAQ.
- Mudflap: Mudflap says its card can be used wherever Visa is accepted. Its app-discounted price is available at more than 3,600 partner stops, and it states a 2-cent-per-gallon discount outside that network. The relevant question is whether the Visa-accepting locations on your route provide a competitive final price after any applicable charges. Details are on the Mudflap Fuel Card page.
- RTS programs: RTS reports an average of 45 cents per gallon at more than 4,000 stations on its current fuel-card page. The page does not define the measurement period or calculation, so treat that as an RTS claim to verify for the exact product and stops you would use. RTS offers distinct structures, including Total Fleet, Self-Funded and Fleet One; do not assume their networks, funding or fees are identical. See the RTS Fuel Card Program page.
Compare documented offers without treating averages as guarantees
The following facts come from the providers’ cited pages and, for the RTS fees, a dated agreement. They are starting points for a quote—not a universal ranking. A provider-reported average is not a promise for your truck, route or future pump price.
| Program | Eligibility and funding description | Network and discount information | Documented fees or conditions | Recordkeeping information |
|---|---|---|---|---|
| TCS Fuel Card | TCS calls the card cash-secured, says there is no credit check and no fleet-size minimum. | More than 12,000 fuel locations; no fuel transaction fee at more than 2,300 in-network locations. TCS reported 49 cents per gallon as an average from actual in-network client transactions in Q1–Q3 2026. The discount is applied after a purchase is processed. | TCS says there are no activation, membership, monthly or annual fees. Out-of-network transaction fees may apply and vary by location. | TCS describes account records as supporting quarterly IFTA reporting; that is a recordkeeping aid, not proof that the card alone satisfies every reporting obligation. |
| Mudflap Fuel Card | Approval is required and the card is subject to credit approval. | Usable wherever Visa is accepted; app-discounted price at more than 3,600 partner stops and a stated 2-cent-per-gallon discount outside its network. Savings vary by stop, volume and market conditions. | Mudflap says there are no annual or monthly service fees, but directs applicants to its Business Charge Card Agreement and Fuel Card Reward Terms for applicable charges and conditions. Its “up to $130 per fill-up” example assumes a 75% fill of a 300-gallon tank at network transactions during May–July 2024; it is an illustration, not a typical or guaranteed saving. | The cited page does not establish that the card alone meets a carrier’s fuel-tax record requirements; ask what exports and records are available. |
| RTS / Fleet One | RTS describes Total Fleet, Self-Funded (funded by an uploaded debit or credit card) and Fleet One, which it describes as a credit line of up to $3,200 per truck per week. These are separate products. | RTS states an average of 45 cents per gallon across more than 4,000 stations on its current page; the page does not state the measurement period or calculation. | The RTS/WEX Fleet One OTR Business Card Agreement dated 2023 lists $0.50 per in-network fuel transaction, $3 per out-of-network fuel transaction, a $75 one-time account setup fee and $6 per card per month. It also lists certain payment-method, over-limit, returned-item, late and monthly account-maintenance charges. Obtain the current agreement for the exact product. | Confirm available transaction exports, tax fields and retention periods for the specific RTS product before relying on it for bookkeeping. |
TCS’s 49-cent figure and RTS’s 45-cent figure are not directly comparable: TCS identifies Q1–Q3 2026 actual in-network client transactions, while the RTS page does not identify a measurement period or calculation. Compare your own route-level quotes instead.

Understand how the account affects cash flow
A discount can be outweighed by the timing and method of payment. Determine whether you must deposit money before fueling, whether the provider pulls funds by debit or bank transfer, when invoices are due, and how quickly a payment posts. A cash-secured or self-funded account may avoid borrowing but requires working cash before the truck reaches the pump. A credit product can preserve cash until settlement but may require approval, impose a limit or create late and returned-payment charges.
TCS: cash-secured structure
TCS describes its card as cash-secured and says there is no credit check or fleet-size minimum. That may suit an independent operator who wants to avoid a credit application, but ask how much money must be available, when it is reserved, and what happens after a declined or reversed transaction. “No credit check” does not mean no funding requirement.
Mudflap: credit approval
Mudflap’s page says approval is required and the card is subject to credit approval. Ask about the application criteria, credit limit, statement date, payment due date and consequences of a late or returned payment. The absence of annual or monthly service fees does not remove charges described in the card agreement or reward terms.
RTS product choices
RTS’s Total Fleet, Self-Funded and Fleet One descriptions represent different funding arrangements. Self-Funded uses an uploaded debit or credit source. Fleet One is described as offering up to $3,200 per truck per week, but “up to” is not a guaranteed limit and does not describe every applicant. Request the exact limit, settlement schedule, funding method and all payment-related fees for the product offered to you.
Audit every fee before comparing discounts
Request a complete, current fee schedule rather than relying on a “no monthly fee” headline. At minimum, check:

The cited RTS/WEX agreement dated November 22, 2023 illustrates why the date matters: it lists $0.50 for an in-network fuel transaction, $3 for an out-of-network fuel transaction, $75 for one-time account setup and $6 per card per month, plus other payment and account charges. Those figures are terms of that dated agreement, not a statement that every current RTS applicant receives them. Mudflap likewise directs customers to its Business Charge Card Agreement and Fuel Card Reward Terms for applicable charges and conditions. Keep the document that governs your account.
Check eligibility and application requirements
Independent truckers often search for “no credit check” cards, but eligibility is only one part of the decision. A no-credit-check offer may still require a cash balance, identity verification, business documents or limits on where and how the card can be used. A credit-approved card may offer a different payment window but require a personal or business credit review.
Before applying, ask:
- Is a federal tax ID, motor-carrier authority, business bank account or operating history required?
- Is approval based on personal credit, business credit, a cash deposit or a combination?
- How many cards can the account issue, and can a sole proprietor qualify?
- What is the initial and maximum fuel limit, and how is it changed?
- What documents are needed if the application is declined or placed under review?
Apply only after you know the funding and fee terms. An approval that cannot support your normal weekly fuel volume is not a practical approval.
Use controls to protect the account
Fuel cards concentrate recurring business spending, so controls can be as valuable as a discount. Ask whether the provider lets you set driver or card limits, restrict purchases to fuel, control days or times, require odometer or vehicle data, receive decline alerts and freeze a card immediately. Confirm whether controls are available in the app, online portal or only through customer service, and whether changes take effect instantly.
Recommended Free Tools
For a one-truck operation, sensible controls include a limit that covers the planned route without leaving a large unused balance, a separate card for a relief driver, and immediate notification of unusual gallons or locations. Do not assume a network logo is a fraud-control feature; verify the specific settings included with your agreement.
Make sure records will support bookkeeping and IFTA work
A useful account should provide downloadable transaction records showing date, location, gallons, product, price, discount, fees and vehicle or driver information where available. Check the file formats, export frequency, retention period and whether corrections are traceable. Reconcile the card statement to fuel receipts and your mileage records; a card record does not replace records required by your tax jurisdiction.
TCS says its account records support quarterly IFTA reporting. Treat that as a recordkeeping aid, and confirm that the fields and jurisdictional details match your filing process. For Mudflap and each RTS product, ask the provider to demonstrate a sample export before you rely on it for tax preparation. Keep receipts for exceptions such as cash purchases, mixed-product transactions or a card outage.

A route-first process for choosing a card
- List your normal operating pattern. Record the lanes, states, weekly miles, expected gallons, preferred truck stops, backup locations and the time of day you usually fuel. Separate fuel for the tractor from reefer or other purchases.
- Collect current prices. For several representative trips, capture the cash or posted price at the exact locations you could use. Note whether a card quote is based on cash, retail or another benchmark.
- Shortlist programs that fit the route. Use each provider’s current locator or app. Mark the stations that are physically accessible, open during your schedule and within network rules. Include at least one backup and one out-of-network location.
- Request the governing documents. Obtain the current agreement, fee schedule, reward terms, funding instructions, settlement calendar and eligibility criteria. Ask the provider to identify the product name and version in writing.
- Build a same-input comparison. Put the same gallons, prices, locations and time period into the net-cost formula for every offer. Add transaction fees and allocate recurring or one-time charges. Show first-month and steady-state totals separately.
- Test cash flow. Calculate the balance or credit limit needed for your highest-fuel week. Include the time between fueling and settlement, weekends or bank holidays, and the result of a declined or returned payment.
- Verify controls and records. Ask for a sample statement or export, test the location and purchase controls, and confirm how quickly a lost card can be frozen and replaced.
- Run a short review period. For the first billing cycle, compare every card transaction with the pump receipt, the quoted discount and the statement fee. Recalculate the route-level net cost before expanding use.
Common mistakes and how to avoid them
Choosing the largest advertised discount
A provider-reported average or maximum may not apply to your state, stop, fuel grade or purchase volume. Use the exact locations you can reach and treat historical averages as context only.
Ignoring out-of-network fills
One emergency fill with a fixed fee can erase the saving from several discounted purchases. Model backup stops and ask how the card handles a location that changes network status.
Assuming “no monthly fee” means free
Transaction, setup, payment, late, returned-item, over-limit and per-card charges can still apply. Read the agreement and add every recurring and one-time amount to the calculation.
Confusing an approval promise with available credit
“Up to” limits, subject-to-approval language and cash-secured funding all require confirmation. Ask for the actual limit, available balance rules and settlement date for your account.
Relying on the card as the entire tax record
Statements can simplify bookkeeping, but they do not automatically satisfy every IFTA or state record requirement. Reconcile card data with mileage, jurisdiction and receipt records.

Failing to preserve the terms used in the comparison
Save the dated fee schedule and agreement. If the provider changes a discount, network rule or charge, you need the original terms to explain a later difference.

Which type of card fits your situation?
Choose a cash-secured or self-funded structure when liquidity is available before fueling
This approach can make sense when avoiding a credit check is important and you can keep enough money available for the busiest week. Confirm deposit timing, balance holds and what happens when the account is short.
Choose a credit structure when settlement timing is worth the cost
A credit line may reduce the need to pre-fund every fill, but compare the total cost of payment timing with transaction and account fees. Confirm approval, limit increases, due dates and late-payment consequences.
Choose the broadest practical network, not the broadest advertised network
If your lanes are concentrated around a few corridors, a smaller network with reliable, low-cost stops can beat a national count that rarely fits your schedule. Conversely, a wide network may justify its fees when you regularly cross regions with limited alternatives.
Choose stronger reporting when administrative time is expensive
If you prepare your own books, prioritize exports that identify gallons, location, date, price, fees and vehicle. If a preparer handles IFTA, ask what file format and fields they accept before enrolling.
Questions to put in writing before enrollment
- What exact net price would apply at each of my five most-used fuel stops today?
- When is the discount applied, and is it calculated from cash, retail or another price?
- What are the in-network and out-of-network transaction fees at those stops?
- What are every setup, per-card, monthly, payment, late, returned-payment and over-limit charge?
- How much must be prefunded, what is the credit limit, and when does settlement occur?
- What approval checks and documents apply to an independent owner-operator?
- Which controls, alerts, card-freeze functions and driver restrictions are included?
- Can I export transaction data with gallons, locations, prices, discounts and fees in a format my bookkeeping or IFTA process accepts?
- Which current agreement and fee schedule govern my account, and how will changes be communicated?
The best choice is the offer that wins this written, route-specific comparison after all costs and cash-flow effects are included. Re-run it when your lanes, fuel volume, station access or the card agreement changes.
