Managing fuel costs is one of the biggest challenges for FedEx P&D contractors. With dozens of fuel card options available, choosing the right one can mean the difference between thousands saved and thousands wasted.
We've reviewed the six most popular fuel cards used by FedEx ISPs and rated them on what matters most: rebates, network coverage, reporting quality, and integration with payroll systems like FleetWage.
What to Look for in a Fleet Fuel Card
Before diving into reviews, here's what matters most for FedEx contractors:
- Rebate per gallon — Even $0.02/gallon adds up fast across a fleet
- Station coverage — Cards are only useful if drivers can find participating stations on their routes
- Transaction controls — The ability to restrict purchases to fuel-only prevents misuse
- Reporting — Real-time transaction data helps you catch problems early
- Payroll integration — Automatic import into your payroll system saves hours of manual reconciliation
1. WEX Fleet Card
WEX is the industry standard for fleet fuel cards, and for good reason. Their acceptance network covers 95% of US fuel stations, which means your drivers will almost always find a participating station.
Rebate: Up to $0.06/gallon based on volume Best for: Large fleets (20+ vehicles) needing comprehensive fraud controls
The standout feature is their driver-level purchase controls. You can set limits on transaction amounts, fuel types, and time-of-day restrictions. Combined with real-time alerts, it's the most robust fraud prevention system available.
WEX integrates directly with FleetWage, meaning fuel transactions are automatically imported and matched to each driver for payroll deductions.
2. Coast Pay
Coast Pay is the new kid on the block, but they've made a strong impression with their modern mobile experience and simple onboarding.
Rebate: Up to $0.05/gallon Best for: Tech-forward fleets wanting a modern interface
Their mobile app is genuinely excellent — drivers can find nearby stations, track spending, and receive digital receipts. For fleet managers, the analytics dashboard provides clear spend breakdowns without the learning curve of legacy platforms.
3. Piston Fuel
If maximizing per-gallon savings is your top priority, Piston Fuel offers the highest rebate potential in our comparison.
Rebate: Up to $0.08/gallon Best for: Fleets in areas with good Piston Fuel station coverage
The tradeoff is a smaller acceptance network and more basic reporting tools. But if your routes pass through areas with Piston Fuel stations, the savings can be substantial.
4. Fuelz
Fuelz hits a sweet spot for mid-size fleets that want simplicity without sacrificing essential features.
Rebate: Up to $0.05/gallon Best for: Mid-size fleets (10-30 vehicles) wanting easy setup
No complicated pricing tiers, no lengthy contracts. You sign up, receive cards, and start saving. Their driver app is straightforward and their customer support is responsive.
5. Sunoco Fleet Card
Sunoco's fleet card is a strong choice for East Coast operators, particularly in the Mid-Atlantic and Southeast regions where Sunoco stations are abundant.
Rebate: Up to $0.06/gallon Best for: East Coast fleets near Sunoco stations
Volume discounts reward loyalty, and their online portal provides decent customizable reports. The main limitation is geographic — if your routes aren't near Sunoco stations, this card won't work for you.
6. Comdata
Comdata is the enterprise option — powerful but more complex to set up and manage.
Rebate: Up to $0.07/gallon Best for: Large fleets with IT resources to manage the platform
Their purchase controls are second only to WEX, and their nationwide coverage is excellent. But the platform is designed for enterprise fleet managers, not small ISP owners. Expect a steeper learning curve.
Our Recommendation
For most FedEx ISPs, WEX is the safest choice due to its unmatched acceptance network and strong fraud controls. If you're on the East Coast and price-sensitive, Sunoco is worth considering. And if you want the most modern experience, Coast Pay is impressive.
Whichever card you choose, make sure it integrates with your payroll system. Manual fuel card reconciliation is one of the biggest time sinks for ISP owners — and it's completely avoidable with the right tools.
