Fueling costs is the biggest financial cost for commercial fleets. Fluctuating prices and unauthorized use can increase expenses significantly. Cardlock fueling is a system used by commercial fleets to manage fuel access, allowing controlled fueling through secured stations. This system tracks fuel usage per vehicle, making it easier and more cost-effective to manage and budget.
This method also ensures that only authorized vehicles are refueled. So you don’t have to worry as much about the risk of misuse and theft.
Key Takeaways
- Cardlock fueling systems provide commercial fleets with a secure and efficient way to manage fuel purchases at designated cardlock stations.
- Fleet fuel cards, such as the CFN fuel card, allow drivers to fuel their vehicles while offering managers greater control over fuel expenses and usage.
- Cardlock stations are designed to streamline the fueling process for commercial vehicles, providing access to diesel and gasoline at competitive fuel prices.
What is Cardlock Fueling?
Cardlock fueling is a controlled fuel access system designed for commercial and fleet vehicles to automate unattended fueling stations where drivers access fuel via a secured card system. This setup allows fleet managers to monitor fuel usage and costs more accurately and effectively.
The origin of cardlock systems dates back to the 1980s when these systems provided a solution for fleets needing fuel outside regular business hours. Today, they have evolved into sophisticated networks with extensive control over fuel transactions for the benefit of commercial fleets.
Now you can track more accurately the vehicles refueled, the amount of fuel dispensed, and the time of transaction, which can help in controlling fuel expenses.
The system is also designed to eliminate unauthorized use and improve efficiency by allowing fleet operators to set parameters such as fueling times and limits per vehicle, which helps manage budgets and reduce waste.
How Does Cardlock Fueling Work?

Cardlock fueling allows commercial fleets to use specialized fuel cards at dedicated fueling sites designed for business use. These unmanned stations are accessible only with a cardlock card.
Each driver receives a fuel card linked to the company’s cardlock account, ensuring tight control over fuel access.
To fuel, drivers insert their card into the reader, enter a PIN, and may need to provide vehicle identifiers. Once verified, the diesel or gasoline pump activates.
Transactions are automatically recorded, detailing the fuel dispensed, cost, time, and location, which are sent to the fleet manager for effective fuel management.
Who Uses Cardlock Fueling?
Cardlock fueling is ideal for entities needing efficient fuel access.
Trucking companies gain control over fuel expenses with cardlock systems, while construction fleets ensure timely fueling for vehicles and machinery.
Delivery and logistics businesses track fuel usage effectively, and municipal fleets maintain oversight of fuel costs. This service supports fleet management solutions.
Benefits of Cardlock Fuel System for Fleet Management
By controlling fuel access and monitoring usage, fleets can prevent unauthorized fueling. This reduces wasted resources and helps in budgeting and forecasting expenses accurately since everything is tracked.
“ Better fuel management capabilities come from this detailed transaction tracking. Fleet managers receive data on every fueling event, including the amount of fuel, the cost, and specific details about the vehicle and driver. This information allows for precise management and efficient allocation of resources.
Accessing fuel late in the day can sometimes be challenging due to closing times. But cardlock stations are available 24/7. Drivers can refuel at any time without the need for staffed fuel stations as long as they have their card.
Security is also a big plus for cardlock fuel systems because, through the use of fuel cards and PINs, you are restricting fuel access to authorized users only. This limits the damage of theft and fraud.
How Cardlock Differs From Retail Gas Stations
| Feature | Cardlock Fueling | Retail Fueling |
|---|---|---|
| Access | Fuel card only | Public access |
| Hours | 24/7 | Business hours vary |
| Payment | Postpaid, account-based | Credit/debit card |
| Reporting | Fleet data tracking | Basic receipt only |
| Target user | Businesses | Consumers |
Both of these stations target a different type of user. As mentioned in this guide, cardlock stations are primarily for commercial fleets, not the general public due to the features it offers. Individuals can’t just go to a cardlock station. The only way a vehicle accesses the fuel is through the company card.
Plus, this type of station is ideal for large vehicles and is available 24/7. Large truck drivers need these features to reliably get fuel.
“ Another main difference is that cardlock fueling stations track all data available and send it to the manager. This feature is not really necessary for individuals. Fleet drivers have tight fuel budgets that affect the whole business. So, with all this information available, they can make the best decisions to maximize their fuel usage.
People are used to traditional retail fueling stations. While some provide diesel fuel, large vehicles aren’t their main customer. Otherwise, with the limited space, there would be a lot of traffic and complications. Plus, they are not automated as cardlock stations.
In traditional fuel stations, you might also be able to use a company card to make your purchases. However, you don’t get the security or tracking features. In cardlock stations, you can’t get fuel without a card. In retail ones, you can.
Requirements for Using a Cardlock Account
To effectively utilize a cardlock fueling system, businesses must adhere to specific requirements that ensure compliance and operational efficiency. Setting up a business account requires a few essential elements to facilitate seamless fuel access for drivers and vehicles.
- Business account setup
- Valid business license or DOT number
- Assigned fuel cards per driver or vehicle
- Compliance with local fuel tax rules
Types of Fuel Available at Cardlock Stations

The most commonly available fuels are diesel and unleaded gasoline, the most popular fuels for this type of vehicle. Diesel, especially, is a staple at these stations due to its prevalence in heavy-duty vehicles and trucks that require robust fuel options for long-distance and high-load transport.
In addition to standard fuels, cardlock stations can also offer biodiesel, which is a cleaner-burning alternative made from natural, renewable sources. Companies that want to reduce their carbon footprint choose this fuel for that reason.
In some cardlock locations, you can also find specialty fuels. For example, propane and kerosene, which may be necessary for specific vehicles or equipment used in certain industries, such as agriculture or construction.
High-octane racing fuels or aviation gasoline are less common but you could have the luck of finding them in certain stations. Obviously, traditional retail fuel stations don’t over the variety that heavy-duty vehicles require.
