Diesel Prices Surge Past Gasoline: What Dispatchers Must Brace For

Diesel up **$0.42/gal** since the Iran conflict, outpacing gasoline by **$0.28**, tightening margins for fleets across the US and Canada.

Ekjot's take — working-carrier commentaryFuel isn’t a pass‑through cost any more – lock in surcharges or watch your margins melt.

The diesel market is on fire. Since the Iran‑Israel flare‑up in early March, diesel has outperformed every other refined product, climbing $0.42 per gallon to $4.72/gal in the U.S. spot market, while gasoline lags at $4.44/gal. The price gap, now $0.28, is squeezing carrier cash flow and forcing dispatchers to rethink load planning.

What happened

The conflict sparked a sudden spike in crude‑oil risk premiums, but diesel felt the heat harder because of tighter global inventories and a surge in demand from European freight haulers re‑routing around the Red Sea. Simultaneously, U.S. refineries are running at 85% capacity after a series of unplanned outages, limiting diesel output. The result: a perfect storm that pushed diesel futures to a 5‑year high while gasoline stayed relatively flat.

Why it matters for dispatchers/drivers

Higher diesel translates directly into higher operating costs. A typical 80,000‑lb tractor‑trailer burns about 6.5 mpg on the highway. At $4.72/gal, that’s $0.73 per mile in fuel alone, versus $0.65 a month ago – an extra $6,500 per year for a 9,000‑mile monthly run. Dispatchers must now factor fuel surcharges into every rate quote, renegotiate contracts, and watch load‑to‑mile ratios tighter than ever. Drivers see lower take‑home pay unless the carrier passes the surcharge forward.

My take

The diesel spike is a wake‑up call: carriers can’t keep treating fuel as a “pass‑through” expense. It’s time to lock in longer‑term fuel contracts, invest in fuel‑efficient tech, and train drivers on eco‑driving. Anything less is a recipe for margin erosion and driver dissatisfaction. – Ekjot Singh

What you should do

  • Negotiate fuel‑surcharge clauses in every contract; aim for a **$0.05‑$0.10/mi** buffer.
  • Push your carrier to adopt **AECC‑approved aerodynamic kits** and **low‑rolling‑resistance tires** – they shave up to **0.3 mpg**.
  • Enroll in EK Dispatch Academy’s **Fuel‑Management Module** (see /curriculum) to learn real‑time fuel‑price tracking and load‑optimization tactics.
