Diesel Exceeds $5 per Gallon in the United States (March 2026)

Washington, D.C. — The national price of on-highway diesel fuel (No. 2) in the United States exceeded $5 per gallon on March 16, 2026, reaching an average of $5.071 per gallon, according to the U.S. Energy Information Administration (EIA) ⛽💸

Steady Increase in March

Diesel prices have shown a continuous upward trend in March 2026:

• March 2: $3.897/gallon
• March 9: $4.859/gallon
• March 16: $5.071/gallon 📈

This represents an increase of nearly $1.20 per gallon in just two weeks — a heavy blow for truckers and owner-operators.

Prices by Region (March 16)

Diesel cost varies significantly by region:

• West Coast: $5.85/gallon (highest, excluding California)
• East Coast: $5.10/gallon
• Midwest: $4.97/gallon
• Gulf Coast: $4.83/gallon (lowest)
• Rocky Mountain: $4.79/galón
• California: $6.428/gallon 😱 (national record)

Cause: Middle East War

The price surge is partly attributed to the ongoing Middle East conflict impacting crude oil markets. The EIA's Short-Term Energy Outlook (March 2026) projects diesel will average $4.12 per gallon for all of 2026 — but current spikes exceed that forecast.

Impact on the Trucking Industry

Diesel above $5/gallon puts enormous financial pressure on operators, especially small ones:

• 🚛 A long-haul truck running 100,000 miles/year at 6 MPG consumes ~16,666 gallons
• 💰 At $5/gallon = $83,330 annually in fuel
• 📊 Compared to $3.50/gallon = $58,331 — a difference of $25,000 per year

How to Reduce Diesel Consumption?

With such high prices, every MPG counts. Here are some strategies:

1. Preventive maintenance: Clean filters, fresh oil, correct tire pressure
2. Truck alignment: Misaligned tires increase rolling resistance and burn more diesel 🔧
3. Go Green APU: If you idle a lot, consider an APU (Auxiliary Power Unit) to avoid burning diesel while resting. Go Green APU helps save thousands of dollars per year ⚡
4. Efficient driving: Avoid hard acceleration, use cruise control, reduce speed
5. Tire inspection: Worn or unbalanced tires reduce efficiency
