Fuel Your Fleet.
Simplify Your Day.

A fuel card, also called a fleet card, lets a business pay for fuel at participating locations. Purchases are recorded through the card program, helping you track fuel spending and apply the controls available for your account.

A Cardlock location is a commercial fueling site designed for authorized fleet and business customers. Many are arranged for trucks and equipment. Hours, accepted cards and available products—including gasoline, diesel and DEF—vary by location, so check the site before you travel.

Acceptance depends on the card and network you choose. InterState offers CFN and Pacific Pride programs, with access to participating commercial sites and, for eligible cards, retail stations and truck stops. Use our network locators to check stops along your route.

A fleet fuel card can combine fuel-specific purchase limits, PIN security and detailed transaction records in one program. These tools help you oversee driver and vehicle spending. Available controls and pricing depend on the card and account you select.

CFN and Pacific Pride are separate commercial fueling networks. Their participating locations and available card options differ. The Cardlock team can compare the networks against your routes, vehicles and need for retail fueling access.

Start with an online Cardlock inquiry or contact our team. Have your business details, contact information and estimated fuel needs ready. The team can explain the application, credit requirements, account terms and expected review time.

Ask the Cardlock team for the current fee schedule for the program you are considering. Confirm any setup, monthly or transaction charges, along with billing and payment terms, before opening your account.

Pricing depends on the program, account and fueling location. Ask about available cost-plus or retail-minus options and how your price is calculated. The Cardlock team can explain the current terms so you can compare options for your fleet.

Maintenance purchasing may be available with certain cards and account settings. Before using a card for oil changes, tires or repairs, ask the Cardlock team which purchases and service locations your program allows.

Available controls can include fuel type or grade, gallons per transaction or card, daily, weekly or monthly gallon limits, and fueling times or days. Ask about ZIP code or state restrictions, retail purchase limits, PINs, odometer entry and transaction alerts for your program.

Use the online Cardlock account portal to review transactions, manage cards and download available files and reports. Ask about invoice access, summaries by driver or vehicle and IFTA fuel-tax reporting support for your account.
