Pros
- Excellent Pilot Flying J discounts
- Moneycode cash advance system is very convenient
- Strong IFTA fuel tax reporting
- Widely accepted at major truck stops
Cons
- Monthly fee can be high vs alternatives
- Customer service has mixed reviews
- Smaller network than EFS overall
Our VerdictComdata is a rock-solid choice, especially if you run heavily through Pilot Flying J locations. The Moneycode system for cash advances is one of the most convenient features in the industry. Slight edge to EFS on pure network size and discount depth, but Comdata is an excellent alternative or second card.
WEX
WEX Fleet Card
Strong universal network • Good for mixed fleets

QuikTrip
+45,000 locations (inc. retail)
Pros
- Widest network including retail fuel stations
- Good for mixed fleets (trucks + vans + cars)
- Strong fraud protection
- Detailed expense reporting
Cons
- Truck-stop discounts lower than EFS/Comdata
- Better suited for fleets than solo O/Os
- Some reports of slow customer support
Our VerdictWEX shines if you operate a small fleet with mixed vehicles, since it works at retail stations too. For a solo owner-operator running OTR, EFS will typically out-discount WEX at major truck stops. Worth considering as a backup card for areas where EFS coverage is sparse.
MUD FLAP
Mudflap
App-based, no credit check, pay-as-you-go
★★★★★

Cons
- Must pay before fueling (no float)
- Smaller network than EFS/Comdata
- Lower discounts than premium cards
Our VerdictMudflap is the best starting point for brand new owner-operators or drivers with limited credit history. No approval process, no monthly fee, and real discounts at major chains make it risk-free to try. Once your credit and volume are established, add EFS for deeper discounts.

Pro Tips for Maximizing Fuel Savings
Stack two cards
Use EFS or Comdata as your primary card and keep Mudflap as a backup. When one network has thin coverage on your route, the other fills the gap.
Time your fill-ups
Diesel is typically cheapest Tuesday through Thursday. Avoid fueling Friday through Sunday when prices spike due to weekend demand.
Use IFTA reporting
Cards like EFS and Comdata automatically generate IFTA reports, saving you hours of manual logging every quarter and reducing filing errors.
Fuel in cheaper states
State fuel taxes vary by $0.30–$0.60/gal. Top off in low-tax states (TX, MS, NM) before crossing into high-tax states (CA, PA, CT).
Negotiate volume tiers
If you’re fueling 10,000+ gallons per month, call your fuel card rep and ask about volume discount tiers. Most cards have them but don’t advertise them.
Watch transaction fees
Some cards charge $0.25–$1.00 per transaction. If you fuel frequently in small amounts, those fees can eat into your per-gallon discount significantly.
1. The Discount Structure (Cost Savings)
This is usually the primary reason a driver chooses a card, but not all discounts are calculated the same way:
- Cost-Plus Pricing: Often found with EFS and Comdata. You pay the price the truck stop paid for the fuel (the “rack price”) plus a small fee. This usually offers the biggest savings at major chains.
- Retail-Minus: A flat cents-per-gallon discount off the price posted at the pump. This is common with WEX.
- Dynamic/App-Based: Mudflap uses this. The discount varies day-to-day based on the specific partner station.
2. Network Size and Accessibility
A card is only as good as the stations that accept it.
- Universal Cards (WEX/FleetOne): Accepted at 90% + of fuel locations. Great for regional drivers who need flexibility.
- Network-Specific (EFS/Comdata): These often have deeper discounts but may be restricted to major chains like Love’s, Pilot Flying J, or TA-Petro.
- Independent Networks (Mudflap): Focuses on smaller, independent stops. This is a huge benefit for owner-operators trying to avoid the high retail prices of the “Big Three” chains.
3. Fee Transparency
Fees can quickly eat up the savings from a 10-cent discount.
- Transaction Fees: What the card charges every time you swipe.
- Monthly Account Fees: Some cards charge a “per-pipe” or “per-card” monthly fee.
- Application/Start-up Fees: Important for new owner-operators to look out for.
- IFTA Reporting Fees: Many cards (like EFS/Comdata) provide automatic IFTA data, which is a massive time-saver for your “Profit Survival Kit,” but some charge extra for the reports.
4. Credit Requirements and Cash Flow
For owner-operators, getting approved is often the biggest hurdle.
- Line of Credit: Traditional cards (Comdata/WEX) usually require a credit check and a personal guarantee.
- Prepaid/Secured: Some providers offer “secured” versions where you load funds in advance. This is great for those building business credit.
- Factoring Integration: Many fuel cards are tied to factoring companies. This offers “Cash Flow Benefits” because your fuel costs are deducted directly from your hauled loads before you even get paid.
5. Added Driver Perks
Since you are ranking these, look for the “extra” value:
- Tire and Maintenance Discounts: Cards that offer discounts at TA-Petro or Loves for tires and oil changes.
- Rewards Points: Does the card link to the truck stop’s rewards program (e.g., earning “shower points”)?
- Fraud Protection: Real-time driver prompts and the ability to “lock” cards via a mobile app.
