Fuel is one of the largest recurring expenses for any business that runs on diesel, and bulk diesel delivery cost varies more than most buyers expect. At FHG Fueling, we help commercial fleets, construction sites, and industrial operations across Dallas-Fort Worth understand exactly what they’re paying for, from the wholesale rack price down to the last delivery fee. Here are the factors that move your per-gallon number.
Current Diesel Prices in Texas
Texas retail diesel is running around $4.21 per gallon as of July 2026, and $0.444 of that is state and federal taxes. Still, that’s good news for Dallas, TX buyers: Texas consistently ranks among the lowest average diesel prices in the country.
Bulk pricing is tied to wholesale rack rates rather than pump prices, so businesses ordering in volume generally pay less per gallon than retail, even after delivery charges. Diesel prices in Dallas fluctuate weekly, so the most reliable number is a current quote. A dependable diesel fuel delivery service should provide fuel delivery price quotes based on your location, volume, and fuel type.
What Goes Into Your Per-Gallon Price
Every invoice comes down to three components. The fuel itself typically accounts for 70 to 80 percent of the bill, with taxes and delivery making up the rest.
Wholesale rack price: Crude oil costs, refinery output, transportation, and regional demand set the baseline. Seasonal shifts or refinery maintenance can tighten supply and push diesel prices up.
Taxes and fees: The $0.20 per gallon Texas excise tax and $0.244 federal excise tax should be itemized separately from the commodity price on a clean invoice. Texas also assesses a Petroleum Products Delivery Fee when fuel is withdrawn from a bulk terminal, charged per delivery and scaled by volume. Suppliers who pay the state on time earn a 2 percent discount (1.75 percent for distributors), which is part of why invoices from different suppliers can look slightly different. Late payment carries a 5 percent penalty in the first 30 days, with interest accruing after that. A reputable diesel fuel distributor handles all of this compliance for you.
Delivery fee: Some suppliers charge a flat rate per delivery, while others price by distance, quantity, and fuel type.
On Road vs. Off Road Diesel: The Biggest Cost Lever
Clear on road diesel includes full state and federal taxes and is required for vehicles on public highways. Off road diesel, often called red diesel because of its dye, is exempt from those road taxes since the equipment never touches public roads.
The difference adds up fast. A company buying 2,000 gallons of clear diesel per month for off-road equipment is overpaying roughly $880 per month in taxes it never owed, about $10,560 per year. Texas allows businesses to register for tax-exempt dyed diesel through the Comptroller’s office, and you can even claim refunds on taxes already paid for fuel used in off-highway equipment like generators and tractors, within one year of purchase.
If you run excavators, cranes, or backup generators, ask your fuel supplier whether your equipment qualifies for dyed diesel pricing.
Volume, Minimums, and Contracts
How much you order and how often shapes your rate more than almost anything else:
5,000+ gallons per month: Commercial accounts at this level often pay $0.30 to $0.50 below retail pump price per gallon.
15,000+ gallons per month: The gap over retail can exceed $0.50 per gallon.
Under 1,000 gallons per month: Retail pumps or fuel cards are usually more economical, since minimum-order fees erase wholesale savings.
Minimum delivery quantities: Most suppliers require 100 to 500 gallons per delivery, worth knowing when sizing diesel fuel tanks. Fuel tank rental is also an option if you’re not ready to buy.
Customers with scheduled fleet fueling or on-site fueling contracts typically pay less per gallon than one-off orders, and flexible payment options make budgeting easier.
Distance, Access, and Timing
Delivery logistics affect pricing too. Deliveries within the metroplex, from Dallas and Fort Worth to Grand Prairie, TX, are typically more efficient than remote sites, since shorter routes keep fuel delivery trucks moving. Rural roads, hard-to-access industrial operations, and after-hours requests can all carry surcharges, and those compound for emergency fuel delivery. Scheduled mobile refueling and generator fueling routes keep costs predictable, while disaster planning and response programs ensure priority service when it matters most.
How to Read a Bulk Diesel Quote
Not all fuel delivery options are priced transparently. Watch for these red flags when comparing quotes:
Vague fuel surcharges: Line items not tied to a named index like the EIA weekly diesel average
Undisclosed minimums: Minimum-order fees that only appear on the invoice
Unverified quality claims: “Premium diesel” without batch documentation
A trustworthy diesel fuel supplier itemizes every charge and names its pricing index. It should also stand behind fuel quality with services like diesel fuel polishing and cold and hot weather fuel blends matched to Texas conditions.
