Critical Fuel Sourcing for Carriers

For carriers, fuel costs are a significant and volatile part of the budget that directly impacts margins and profitability. The key to gaining control is not just finding the cheapest fuel along a lane, but implementing a structured approach to how you purchase it across your entire network. From choosing the fueling method, like fuel cards, bulk fuel, and mobile fueling, to validating you are receiving the best possible price and discounts, a well-defined strategy is essential. This guide covers the core sourcing strategies, common challenges, and how to improve your fuel sourcing methods for a more efficient and profitable operation.

Key takeaways

• Fuel sourcing is not one-size-fits all: It involves selecting the right suppliers, purchasing methods, and pricing structures for your fleet.
• Various fuel sourcing options are available: Carriers can use fuel cards for network access, bulk fuel for cost savings in owned yards, and mobile fueling to adapt to price differences by location.
• Gaining efficiency requires optimization: Consolidating providers, aligning fuel sourcing with routes, and ensuring driver compliance are key tactics for improving efficiency.
• Optimization often results in cost savings: The actual cost of fuel determined by your sourcing strategy may not align with index-based surcharge structures, creating potential gaps in margin.

What is fuel sourcing?

Fuel sourcing is the process carriers use to determine how, where, and from whom they purchase fuel. The process includes selecting fuel suppliers, choosing the right fueling methods for your fleet, and negotiating favorable pricing structures. It is important to clarify that fuel sourcing focuses specifically on the procurement of fuel, which is one component of a comprehensive fuel management program.

Why does fuel sourcing matter for carriers?

Fuel is consistently one of the largest variable costs for any carrier. Because of this, the decisions made around fuel sourcing have a direct impact on a business's bottom line.  

An effective fuel management strategy involves considerations in several key areas:

• Operating costs: A strategic approach to fuel sourcing can lower your cost per gallon and create substantial savings across the fleet.
• Pricing consistency: Securing stable, predictable fuel prices helps with financial forecasting and protects margins from market volatility.
• Driver behavior: A clear fuel sourcing plan guides drivers to preferred, in-network fueling locations, preventing out-of-network purchases at higher retail prices.

Core fuel sourcing options

Fuel cards

Fuel cards provide drivers with access to extensive merchant locations and fuel card discounts. Using multiple fuel cards often complicates management whereas a consolidated fuel card program with structured, cost-plus pricing improves transparency and control.  

Bulk fuel

For fleets with dedicated space and storage infrastructure, purchasing bulk fuel can offer a lower cost per gallon. This method requires careful planning for inventory management and upfront investment in tanks, but the long-term savings can be significant.

Mobile fueling

Mobile fueling services deliver fuel directly to your trucks, often overnight. This strategy ensures vehicles are fueled and ready to go without losing time at truck stops or spent at the bulk fuel tank.

Fuel sourcing strategies for cost control

Consolidate fuel providers

Working with fewer fuel providers and suppliers can increase your purchasing volume with each one, improving your negotiating leverage. Consolidation also simplifies decision-making for drivers and makes it easier to manage compliance and payment processes.

Align sourcing with routes

Carriers can achieve greater efficiency by aligning their preferred merchant locations with established route patterns. Analyzing routes to identify the most cost-effective fueling stops helps reduce unnecessary mileage and directs drivers to merchant locations where you have the best pricing.

Monitor driver compliance

Negotiated savings are only realized if drivers use the in-network merchant locations. Monitoring driver compliance is essential to ensure your fuel sourcing strategy is being followed. Implement clear communication and reporting to track adherence and address any out-of-network spending.

Compare costs to fuel surcharges

Carriers should regularly evaluate if fuel surcharge structures accurately reflect their actual fuel costs. Index-based models like the DOE fuel price index may not capture the true price paid at the pump, potentially leading to a gap between your costs and what you recover.

Common fuel sourcing challenges

Diesel price volatility

Rapid and unpredictable changes in diesel prices make fuel costs difficult to forecast. In volatile markets, negotiating and realizing fuel card discounts become imperative to business success and protecting your budget.

Route variability

Fleets with inconsistent routes face added complexity. Without a structured fuel sourcing approach that accounts for this variation, carriers risk increased costs and operational inefficiencies.

Driver compliance

Even with a solid strategy, drivers fueling at out-of-network retail locations can quickly erode savings. Fuel card discounts only protect your bottom line when drivers actually fill up at in-network merchant locations; otherwise, negotiated savings are lost at the pump. Ensuring drivers understand and adhere to the fueling plan is a persistent challenge that requires ongoing management.

How fuel sourcing connects to fuel surcharges

Fuel sourcing and fuel surcharges are two sides of the same coin. Your fuel sourcing strategy determines your actual cost, while the fuel surcharge program dictates how you recover those costs from your shipping partners. A misalignment between your real sourcing costs and the structure of your fuel surcharge rate can create significant margin gaps, either leaving money on the table or overcharging clients.

Frequently asked questions about fuel sourcing

Why is fuel sourcing important for carriers?

Fuel sourcing is important because it directly addresses one of the largest variable costs a carrier faces. A strategic approach to fuel sourcing allows a carrier to control expenses, improve pricing consistency, and protect profit margins from fuel market volatility. By optimizing where and how fuel is purchased, companies can guide driver behavior, reduce out-of-network spending, and achieve significant operational savings that contribute directly to the bottom line.

What are the most common fuel sourcing methods?

The most common fuel sourcing methods are fuel cards, bulk fueling, and mobile fueling. Fuel cards offer access to wide networks and negotiated discounts. Bulk fueling allows carriers with their own storage tanks to buy large quantities at a lower cost per gallon. Mobile fueling fills up trucks in a yard, which increases convenience and allows fleets to still take advantage of favorable pricing.

How can carriers reduce fuel sourcing costs?

Carriers can reduce costs by consolidating their fuel card providers to increase negotiating power and simplifying operations. Aligning fueling locations with established routes minimizes unnecessary mileage and ensures drivers fill up at in-network merchant locations. Monitoring driver compliance is also critical to ensure that negotiated savings are realized. Finally, comparing actual fuel costs to surcharge schedules helps identify and close any gaps in repayment.
