Average Price for Fuel

Fuel is one of the biggest variable costs in trucking, often eating up 25% to 35% of your operating budget. As of mid-2026, the national average for diesel sits around $3.85 per gallon, with gas averaging $3.20. But those are just averages: your actual cost depends on region, taxes, and your buying strategy. Here’s what you need to know to budget accurately and keep more money in your pocket.

National Average Diesel Prices (2026)

Diesel prices have stabilized somewhat after the volatility of the early 2020s. As of June 2026, the U.S. average for on-highway diesel is approximately $3.80 to $4.00 per gallon. Gasoline averages $3.10 to $3.30 per gallon. These figures come from the Energy Information Administration (EIA) and reflect retail prices at truck stops and fuel stations.

Keep in mind that these are national averages. Your actual price will vary based on where you fill up, the type of fuel (e.g., #2 diesel vs. biodiesel blends), and whether you’re buying at a major truck stop chain or a small independent station.

Regional Price Variations

Fuel prices vary significantly by region due to taxes, supply logistics, and state regulations. Here’s a rough breakdown of average diesel prices by region (as of mid-2026):

Region	Average Diesel Price per Gallon
East Coast (PADD 1)	$3.95 - $4.15
Midwest (PADD 2)	$3.70 - $3.90
Gulf Coast (PADD 3)	$3.55 - $3.75
Rocky Mountain (PADD 4)	$3.85 - $4.05
West Coast (PADD 5)	$4.30 - $4.60

California often has the highest prices, sometimes $1.00 or more above the national average due to stricter environmental regulations and higher taxes. The Gulf Coast tends to have the lowest prices due to proximity to refineries.

How Fuel Prices Affect Your Bottom Line

Let’s put these numbers into perspective. If you drive an average of 120,000 miles per year and get 6 miles per gallon, you’ll burn about 20,000 gallons of diesel annually. At $3.85 per gallon, that’s $77,000 per year just for fuel. A difference of just $0.10 per gallon adds up to $2,000 per year. That’s why even small savings matter.

Fuel is also a major factor in your cost per mile (CPM). If you’re an owner-operator, you need to know your CPM to set your rates. For example, if your total operating costs are $1.80 per mile and fuel is $0.64 per mile (at $3.85/gal and 6 mpg), you need to charge at least that much to break even.

Practical Tips to Save on Fuel

You can’t control the price at the pump, but you can control how much you pay and how much you burn. Here are actionable steps you can take this week:

• Use fuel discount programs: Most major truck stops (Pilot Flying J, Love’s, TA/Petro) offer loyalty programs that give you discounts of $0.05 to $0.15 per gallon. Sign up for free and use them consistently.
• Compare prices with apps: Apps like Trucker Path, GasBuddy, and Fuelster show real-time diesel prices at nearby stations. Check before you fill up.
• Plan your fuel stops: Don’t wait until you’re on empty. Plan your route to fill up in areas with lower prices, like the Gulf Coast or Midwest, when possible.
• Reduce idling: Idling burns about 0.8 to 1.0 gallons per hour. If you idle 8 hours a day, that’s 8 gallons wasted. Use an APU or engine block heater instead.
• Maintain proper tire pressure: Underinflated tires increase rolling resistance and can cut fuel economy by 1% to 2%. Check tire pressure weekly.
• Drive at optimal speeds: For most trucks, the sweet spot is 60 to 65 mph. Every 10 mph above 60 can reduce fuel economy by 0.5 to 1 mpg.

Fuel Budgeting for Owner-Operators

If you’re an owner-operator, you need to budget for fuel each month. A good rule of thumb is to set aside 30% of your gross revenue for fuel. For example, if you gross $12,000 per month, plan on $3,600 for fuel. But this varies based on your routes and fuel efficiency.

To get a more accurate estimate, track your fuel expenses for a few weeks. Divide your total fuel spend by your total miles to get your fuel cost per mile. Then multiply that by your expected monthly miles. Add 10% as a buffer for price spikes.

Also, consider using a fuel card that gives you rebates. Many fuel cards offer cash back or discounts of 2% to 5%. Some are tied to specific chains, while others work at any station. Compare options to find one that fits your routes.
