BEST FUEL CARDS FOR TRUCKERS:
REAL SAVINGS COMPARED (2026).

Fuel is your largest expense. At 1,200 gallons/month and $3.80/gallon average, you are spending $54,720/year on diesel. A fuel card that saves $0.20/gallon puts $2,880 back in your pocket. At $0.35/gallon, that is $5,040. For context on where fuel fits in your overall cost structure, see our full owner-operator monthly expenses breakdown — fuel is typically 30% of total operating cost.

The problem is every fuel card claims to offer “huge discounts.” The actual savings depend on where you fuel, how much you buy, and whether the fees eat the discount. Here is how the major fuel cards actually compare.

FUEL CARD COMPARISON: THE REAL NUMBERS

Ranges are wide because discounts vary by station, volume, and whether you are fueling at an “optimized” stop (where the card provider has negotiated a deeper discount) versus a standard stop.

HOW MUCH DOES A FUEL CARD SAVE PER MONTH?

The most common question owner-operators ask is the one people search most: what's the actual monthly dollar impact on my bottom line? Here's what you can expect across different monthly fuel volumes and card types:

The key takeaway: at 1,200 gallons/month (~100,000 miles per year at 6 MPG), the gap between the best card (RTS at $336/month) and doing nothing is $336/month or $4,032/year. That's a truck payment. For higher-volume operators, the annual difference can exceed $6,000. This is why even carriers who hate paperwork should still sign up for a fuel card — the return on 10 minutes of application time is measured in thousands per year.

HOW EACH CARD WORKS

RTS Fuel Card

RTS negotiates bulk discounts at truck stops across the country and passes a portion of that savings to cardholders. The discount per gallon varies by location — some stops offer $0.15 off, others offer $0.42 off. The RTS app shows you the discount at each station before you pull in, so you can plan your fuel stops around the best deals.

Best for: Owner-operators willing to plan fuel stops. The deepest discounts require routing through specific stations, but the savings are significantly higher than loyalty programs. If you can build your routes around 2–3 optimized RTS stops per week, you'll capture the high end of the discount range.

Fees: No annual fee, no monthly fee on the basic card. Some card tiers have transaction fees — confirm your specific plan before signing up.

Network: Major truck stop chains nationwide including Pilot/Flying J, Love’s, TA/Petro, and independent stops. The network is deep enough that most OTR lanes have at least one optimized RTS stop every 250–400 miles.

How you actually use it: Download the RTS Pro app, check the map before your next fuel stop, and route to the station showing the biggest discount. The difference between a $0.15 stop and a $0.42 stop at 150 gallons is $40.50 — worth driving 10 extra miles for.

Mudflap

Mudflap is an app, not a physical card. You open the app at a participating truck stop, it shows you the discounted price, and you fuel up. Payment processes through the app. No card to carry, no application, no credit check.

Best for: Operators who want savings with zero commitment. There is no signup process — download the app, create an account, and fuel. Good for testing fuel discounts before committing to a card. Also ideal for new authorities who haven't built the credit history that traditional fleet cards may look at.

Fees: None. No monthly fee, no transaction fee, no annual fee. This is genuinely a free app — Mudflap earns its cut from the truck stops, not from drivers.

Network: 1,500+ truck stops nationwide. Heavier presence at independent stops and smaller chains where they have negotiated better rates. Coverage gaps exist in some rural lanes — check the app's map before relying on it as your primary fuel solution.

Trade-off: Because Mudflap has no fleet card infrastructure, you can't integrate it with factoring account auto-reimbursement or fleet expense reporting. That's fine for single-truck operators but becomes clunky once you have 2+ trucks.

TCS Fuel Card

TCS (Transport Clearing Solutions) bundles their fuel card with factoring services. If you already use TCS for factoring, the fuel card is a natural add-on. Discounts are moderate ($0.08–$0.15/gal) but consistent across a large network.

Best for: Carriers already using TCS for factoring. The integration between fuel purchases and your factoring account simplifies cash flow management — fuel costs come directly out of your invoice advances, so you're not juggling multiple reimbursement accounts. If you're evaluating factoring companies alongside fuel cards, see our best freight factoring companies guide first — the factoring decision matters more than the fuel card for most new authorities.

Fees: May include transaction fees depending on your factoring agreement. The fuel card itself typically has no separate monthly fee when bundled. Read the factoring contract carefully — sometimes the "free" fuel card comes with higher factoring rates that offset the fuel discount.

Comdata

Comdata is one of the largest fleet card providers. Their network covers virtually every truck stop in the country. Discounts range from $0.05 to $0.25/gallon depending on volume and negotiated rates.

Best for: Small fleets (2+ trucks) that can leverage volume for better rates. Single-truck operators get the lower end of the discount range. The enterprise features (multi-driver authorization, per-truck spending limits, integrated reporting) are overkill for a solo owner-operator but become genuinely valuable at 3+ trucks.

Fees: Monthly fee on some plans ($10–$25/month). Per-transaction fees on some card types. Read the fee schedule carefully — a $15/month fee on modest volume can offset the discount entirely. At 800 gallons/month with a $0.12/gal Comdata discount, you save $96 but pay $15 in fees — netting $81/month, which is less than Mudflap's $200/month at zero fees for the same volume.

WEX / EFS

WEX (formerly EFS) is another large fleet card. Accepted at most major truck stops. Discounts are on the lower end ($0.03–$0.15) for owner-operators. Better rates are available for fleets.

Best for: Carriers who need the widest possible acceptance network and do not want to plan stops around specific stations. If you hate planning fuel stops and just want to pull into whatever's closest, WEX gets you a modest discount at almost every truck stop you'll encounter.

Trade-off: You're giving up $0.10–$0.25/gallon in potential savings for the convenience of universal acceptance. For operators who can plan fuel stops around the deeper-discount cards, that convenience costs $1,500–$3,500/year at typical volumes.

Truck Stop Loyalty Programs (Pilot, Love’s)

Pilot/Flying J and Love’s both offer loyalty rewards programs that provide small per-gallon discounts ($0.02–$0.08). These are not traditional fuel cards — they are loyalty programs that stack with other cards.

Best for: Everyone. These are free to join and stack on top of your fuel card savings. Sign up for both Pilot MyRewards and Love’s My Love Rewards even if you use a separate fuel card. Free money.

How stacking works: Swipe your fuel card first for the main discount ($0.15–$0.42/gal from RTS or Mudflap), then scan your loyalty card when prompted for the additional $0.02–$0.05/gal on top. The loyalty card also earns shower credits, food discounts, and occasional promotional bonuses (like $0.10/gal for a weekend fuel-up) that push total savings higher.

ANNUAL SAVINGS AT DIFFERENT VOLUMES

Here is what each card saves at typical owner-operator fuel volumes, assuming average discounts.

The difference between the best card (RTS at $4,032) and loyalty-only ($576) is $3,456/year. That is money sitting on the table if you are not using a fuel card.

HOW TO CHOOSE THE RIGHT FUEL CARD

Do not overthink this. The decision comes down to four factors.

1. Where do you fuel? Check each card’s station locator against your regular routes. A card with $0.40/gal discounts is worthless if the nearest participating station is 50 miles off your lane. The best card is the one that offers discounts at the stops you already use. Drivers running predictable lanes (say, Dallas to Atlanta weekly) can route-plan easily. Drivers running varied freight out of multiple regions need a card with the widest network even if the per-gallon discount is smaller.

2. What are the fees? A $0.15/gal discount with a $25/month fee saves you $190/month at 1,200 gallons — minus $25 = $165 net. A $0.12/gal discount with no fees saves $144/month. The first card is still better, but the gap is smaller than it looks. Always calculate net savings after fees. The break-even point for a $25/month fee at $0.15/gal savings is roughly 167 gallons/month — below that volume, a zero-fee card wins even with a smaller per-gallon discount.

3. Are you willing to plan fuel stops? Cards like RTS and Mudflap reward you for fueling at optimized stations. If you plan routes around them, you get the deepest discounts. If you fuel wherever is convenient, the savings will be lower. Operators who route-plan around fuel discounts save 30–50% more than those who do not. A simple discipline: pull up the card's app at the end of each day to see where the next-best stop is on tomorrow's route.

4. Do you need fleet reporting? Single-truck operators don't need the enterprise reporting features Comdata or WEX offer. Those features matter once you have 2+ trucks and need to track fuel spend per driver, enforce spending limits, or reconcile purchases against IFTA filings. Start with a simple card (RTS or Mudflap), and upgrade to a fleet card only when you have enough trucks to justify the monthly fees.

FUEL CARD VS FUEL OPTIMIZATION: THE BIGGER PICTURE

A fuel card saves you $0.15–$0.42/gallon. But fuel optimization strategies can save even more:

Route planning. Avoiding 50 miles of deadhead per week saves 8+ gallons — $2,500+/year at current prices. That is more than some fuel cards save.

Speed management. Reducing cruising speed from 68 to 63 MPH improves fuel efficiency by 5–8%. On 100,000 miles/year, that is 700–1,100 fewer gallons — $2,660–$4,180 saved.

Tire pressure. Properly inflated tires improve fuel economy by 1–3%. On $55,000/year in fuel, that is $550–$1,650.

Idle reduction. An idling truck burns 0.8–1.0 gallons/hour. Four hours of unnecessary idling per day costs $18,000+/year. An APU (Auxiliary Power Unit) pays for itself in 6–12 months.

The fuel card is the easiest win — sign up once and save automatically. But combining it with fuel optimization is where the real money is. A carrier who uses an RTS card AND manages speed, routing, and idle time can cut total fuel spend by 15–25%.

There’s one more lever nobody talks about: fuel is your single biggest tax deduction. At $54,720/year in fuel costs and a 27% effective tax rate, every dollar you log as a business expense saves you $14,774 in taxes. But only if you’re tracking it properly — fuel card statements, cash-pay receipts, DEF purchases, and mileage by state (for IFTA). Most owner-operators miss $2,000–$5,000 in fuel-related deductions their first year.

THE BOTTOM LINE

Every owner-operator should have a fuel card. At a minimum, sign up for Pilot and Love’s loyalty programs (free, $500+/year savings). For real savings, add a dedicated fuel card:

Best overall savings: RTS Fuel Card — deepest discounts ($0.15–$0.42/gal), no annual fee, large network. Requires some route planning around optimized stops.

Easiest to start: Mudflap — no card, no application, no fees. Download the app and start saving at your next fuel stop. Average $0.25/gal off.

Best for factoring users: TCS Fuel Card — integrates with TCS factoring, simplifies cash flow. Moderate discounts ($0.08–$0.15/gal).

At 1,200 gallons/month, the right card saves $3,000–$5,000/year. That is real money — enough to cover 3–4 months of insurance or your entire annual maintenance budget. Do not leave it on the table.
