What Are Fuel Cards?

Fleet fuel cards 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.

Detailed Reporting

A detailed invoice sent directly to your account after every single purchase when using a Senergy Cardlock card.



Our fleet fuel cards are exclusively intended for commercial use only. Approval is contingent upon verification of an active business license.

Strategic and Efficient

Our strategically positioned stations are purpose-built for commercial vehicles, eliminating the need to wait in lengthy lines behind compact cars or maneuver through tight retail stations.


Benefits of using commercial fuel cards:


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.

Product Availability

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

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.

Fast Fuel and DEF

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


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.

To Fuel:

  1. Remove nozzle and lift lever to engage.
  2. Begin fueling.
  3. When finished fueling, replace nozzle pushing lever down to disengage.
