Every business needs ways to maximize efficiency while reducing costs. Your fleet can often get overlooked, which leads to high expenses if you’re not careful. When you own and operate a fleet, commercial fuel cards can help keep track of expenses and save money.

How Your Fleet Can Benefit From Cardlock Fueling


Our stations are designed specifically for commercial vehicles, which means that you don’t need to wait in long lines of sub-compact cars or try to navigate a narrow retail station. Plus, every location is conveniently located off a major highway to provide the perfect space to pull off and fuel up.

Fast fuel and DEF

We’ve outfitted our cardlock stations with high flow diesel nozzles, truck and trailer access and satellite pumps. This means you get in and out much faster. Also with bulk DEF available at nearly every location, our cardlock sites are your one-stop-shop.

Product Availability

You have high speed access to clear diesel, red-dyed diesel, unleaded, premium unleaded as well as Diesel Exhaust Fluid (DEF). 


Cardlock stations are for cardlock fuel card members only, and they’re well-lit and maintained. Paying with a fuel card is often safer than using cash at a retail gas station. Plus, managers can monitor fuel cards for any suspicious activity.

Controlled fleet costs

When drivers use their commercial fleet cards, managers and owners know exactly how much is spent and on what. Once you see where that money is going, you can find ways to cut costs and keep employees safe.

What Are Fuel Cards?

Fleet fuel cards work like credit cards that give owners and managers greater control over fuel and maintenance purchases. Unlike a retail gas card or credit card, our commercial fuel cards come with extensive reporting and cost-control restrictions.

Some of the benefits of using commercial fuel cards include:


How it works...

Every vehicle in your fleet is issued a Cardlock Card. The card is tailored based on your product needs. By assigning the card to a specific Vehicle, we can help you with detailed billing, driver habits, and prevent any misuse of the card.

At the Cardlock site

The vehicle driver inserts the card and enters his unique DIN (Driver ID Number). The Driver enters the odometer reading for the vehicle and selects the pump number. At our Senergy Cardlock locations, you can get clear diesel, dyed diesel, unleaded fuel, premium fuel, and DEF. Location may vary for each product. Please visit to see which products are offered at each specific location.
