Diesel Is $6.28. A Year Ago It Was $3.74. Here's What That Does to a Load.

The EIA number came out Monday. On-highway diesel, national average, $6.285 a gallon. That's the highest the government has ever recorded, going back to 1994. Two weeks ago it was $5.97. Same week last year it was about $3.74.

If you broker freight, that number is not news to you. Your carriers have been telling you about it on every call for a month. But it helps to put it on paper, because $6 diesel changes what a fair rate is, and a lot of brokers are still quoting like it's spring.

What $6.28 does to one load

Take a plain dry van run, Houston to Dallas and back to Houston, call it 500 miles round trip. A loaded truck gets somewhere around 6.5 miles per gallon. That's 77 gallons.

At $3.74, that fuel cost the carrier $288.

At $6.28, it costs $484.

Same truck, same driver, same lane, $196 more out of the carrier's pocket before they've paid for anything else. On a load that pays $1,200, the carrier just lost sixteen points of margin to the pump. On a long haul, Laredo to Chicago, the difference is more than $500 one way.

That's the whole story of why your carriers are pushing back on rates that worked in March. They aren't being difficult. The math moved.

The fuel surcharge isn't covering it

Most surcharge tables were built when diesel lived between $3.50 and $4.50. A lot of shippers still run a surcharge that tops out somewhere around $5 and stops climbing. When diesel goes past that ceiling, the gap between what the shipper pays in surcharge and what the carrier burns in fuel lands on the two people in the middle: you and the carrier.

If you have a customer whose surcharge schedule hasn't been updated since 2024, this is the month to bring it up. Not as a favor to the carrier. As the reason your loads are going to start getting turned down.

About the October 1 strike

You've probably seen the posts. Truckers shutting down nationwide on October 1 over fuel prices, grocery shelves empty by the 5th, all of it.

Here's what's actually true as of this week. The posts are real and there are a lot of them. Owner-operators are angry, and they have a right to be, because $6 diesel comes straight out of their paycheck. But nobody is organizing it. The Owner-Operator Independent Drivers Association, which is the group that would know, told fact-checkers it has no knowledge of any planned strike. There's no organizer, no list of demands, no count of trucks committed, no union or trade group behind it. Snopes and a few others looked hard and found nothing behind the rumor except the rumor.

So plan for this: a few drivers park on the 1st because they saw a post, most don't, and freight moves. What you should actually worry about isn't a shutdown. It's the slow version of the same thing, which is already happening. Small carriers can't make the numbers work at $6 and they quietly park the truck for good. Fewer trucks means tighter capacity, and tight capacity means the carrier you've been using for two years takes somebody else's load because it paid $150 more.

Three things to change this month

Re-quote your lanes. Anything you priced before August is stale. Pull the surcharge table your customer uses, check where it caps out, and have the conversation before the carrier has it for you by declining the load.

Pay faster. A carrier fueling at $6 is floating a lot more cash between pickup and payment than they were a year ago. Net 30 was survivable at $3.74. At $6.28, the carrier who takes your load is the one who trusts they'll get paid on time. If your invoicing runs off the load the day it delivers instead of the end of the month, you become the broker they call back.

Watch the carrier's authority closer, not looser. When money gets tight, the bad actors get busy. A carrier who can't cover fuel is exactly the kind of outfit that hands your load to a stranger for a cut and hopes it works out. Double brokering goes up when diesel goes up. Check the MC every time, not just the first time.

Diesel will come down eventually. It always has. The brokers still standing when it does are the ones who paid their carriers fairly and on time while it was expensive, and didn't get burned by a truck that wasn't really a truck.
