Diesel Surges to $5.38/Gallon — Another 30-Cent Jump in One Week

National diesel average hit $5.38/gal (week ending March 23), up 30.4¢ in 7 days. Highest level since July 2022. California paying $6.87/gal. Hormuz crisis keeps pressuring prices.

⛽💸 Diesel shows no mercy

National on-highway diesel average reached $5.38 per gallon for the week ending March 23, 2026, according to data from the Energy Information Administration (EIA) and Overdrive. This represents a jump of 30.4 cents in just one week — the highest level since July 2022, when the Russia-Ukraine war pushed diesel to $5.81/gal.

📊 Regional Breakdown (March 23, 2026)

• California: $6.87/gal 🔥 (highest in the nation)
• Gulf Coast: $5.13/gal (cheapest)
• Midwest: $5.16/gal
• New England: Up 52 cents in one week (largest regional jump)
• West Coast (excl. CA): $5.83/gal

🌍 Why Does It Keep Rising?

1. Strait of Hormuz Crisis

The geopolitical conflict that started in late February keeps disrupting oil flows:

• Brent crude holding above $103/barrel
• ~20% of world's oil passes through Hormuz
• Escalation risk keeps prices elevated

2. Low Inventories

• US diesel stocks below 5-year average
• Refineries still haven't recovered post-maintenance production
• Spring demand (construction, agriculture) accelerating

3. Spot Rates Responding

Truckload spot rates are rising in response:

• According to ProMiles: Spot rates average $5.10/gal all-in
• Carriers passing costs to shippers
• Fuel surcharges adjusting weekly

💰 Impact on Operating Costs

Example: Semi running 2,500 miles/week at 6 mpg

• Weekly consumption: ~417 gallons
• Weekly cost (at $5.38/gal): $2,243
• vs. month ago ($5.08/gal): $2,118 → +$125/week
• vs. year ago ($3.86/gal): $1,610 → +$633/week

Additional Annual Costs:

• +$6,500/year vs. month ago
• +$32,916/year vs. year ago

For an owner-operator, this is unsustainable without rate adjustments.

🛡️ How to Protect Yourself

1. Improve Your Fuel Economy

Each 0.5 MPG improvement saves thousands per year:

• Alignment: Misaligned truck loses up to 1 MPG
• Tire pressure: Check weekly
• Aerodynamics: Keep side skirts, trailer tails in good shape
• Efficient driving: Less idling, smooth acceleration

👉 At The Truck Savers™, we offer free road simulator inspection and precision alignment that can improve your MPG up to 5%.

2. Install an APU

Eliminate idling during breaks and save up to $1,000+/month:

• APU consumes ~0.2 gal/hour vs. diesel engine 0.8 gal/hour
• 8 hours rest × 20 nights/month = 160 gallons saved
• 160 gal × $5.38 = $861/month

👉 Check out options at Go Green APU — they pay for themselves in under 12 months at these prices.

3. Negotiate Real Fuel Surcharges

If your contracts have fixed FSC based on $4/gal, you're losing money:

• Renegotiate FSC indexed to current EIA price
• Shippers understand the situation — they're willing to adjust
• Without proper FSC, every trip is a loss

4. Optimize Routes and Backhauls

• Every deadhead mile costs $2.26+ without generating revenue
• Use smart load boards (DAT, Truckstop)
• Plan round trips when possible

🔮 When Will It Drop?

EIA projects:

• Q2 2026: Average $4.54/gal
• Q3 2026: Average $4.12/gal
• Q4 2026: Average $3.92/gal

But we're already at $5.38 in March — 84 cents above the Q2 projection. If the Hormuz crisis doesn't resolve, we could see diesel above $5/gal all year.

💡 The Bright Side

Freight rates are responding:

• Spot rates up 7th consecutive month
• Dry van: $2.65/mi (+24% vs. year ago)
• Reefer: $2.84/mi (+27% vs. year ago)
• Contract rates adjusting upward

If you negotiate well and optimize costs, this market can be profitable — but you have to be efficient.
