EFS (Electronic Funds Source) — Best for Fuel Discounts
EFS, now part of WEX Inc., is the leading fuel card system for the trucking industry. Its primary advantage is the fuel discount network — EFS cardholders receive negotiated discounts at over 15,000 truck stop locations, including Pilot/Flying J, Love's, TA/Petro, and independent stops.
For an owner-operator burning 1,500-2,000 gallons per month, a $0.10/gallon EFS discount saves $150-$200 per month — $1,800-$2,400 per year. That is significant money for zero extra effort beyond swiping a different card at the pump. The EFS discount alone makes it the preferred fuel card for most owner-operators.
EFS also offers fuel optimization tools that show you which nearby stops offer the lowest net price (pump price minus your discount), helping you plan fuel stops for maximum savings. Their mobile app provides real-time balance, transaction history, and station finder.
Comcheck — Best for Versatile Payment
Comcheck, operated by Comdata (part of Corpay/FLEETCOR), is the industry-standard payment system for over-the-road expenses beyond just fuel. Comchecks can pay for fuel, lumper fees, scales, tire repairs, and other truck-related expenses at over 8,000 locations.
The key advantage of Comcheck is its versatility. While EFS excels at fuel discounts, Comcheck is the system brokers and dispatch services use to send fuel advances, pay lumper fees, and cover other road expenses. If you need cash for a lumper at a warehouse, your dispatcher sends a Comcheck to the nearest truck stop where you cash it.
Many carriers use both EFS and Comcheck — EFS as their everyday fuel card for discounts, and Comcheck for fuel advances and non-fuel expenses. This dual approach maximizes both savings and flexibility. Learn more about Comcheck in our how to use Comcheck guide.
T-Chek — Solid Alternative
T-Chek, also owned by WEX Inc. (the same company as EFS), is a payment system similar to Comcheck. It allows fuel purchases, cash advances, and some maintenance payments at over 6,000 locations. T-Chek functions as a paper check or electronic payment that drivers present at truck stops.
T-Chek has a smaller acceptance network than Comcheck, which limits its usefulness for some drivers. However, if your dispatch service or factoring company issues T-Cheks, they are a perfectly functional payment method. The transaction fees and acceptance at major truck stop chains (Pilot, Flying J, Love's, TA) are comparable to Comcheck.
Which Should You Use?
For Daily Fuel Purchases: EFS
The fuel discounts make EFS the clear winner for everyday fueling. The savings add up to thousands per year.
For Fuel Advances and Lumper Fees: Comcheck
Comcheck's broad acceptance and versatility make it the best option for non-fuel expenses and fuel advances from brokers or dispatch services.
For Maximum Savings: Both EFS + Comcheck
Use EFS for fuel (best discounts) and Comcheck for advances and expenses (broadest acceptance). Most factoring companies and dispatch services can accommodate both.
