The national average price of on-highway diesel in the United States rose 8 cents to $6.352 a gallon in the U.S. Energy Information Administration's latest weekly release, published October 27 — a price more than $2.60 a gallon higher than a year ago, and the number that decides, load by load, whether an owner-operator's week ends in profit or in loss.

Gasoline moved the other way, easing 2 cents to $4.269 a gallon, according to the EIA figures reported by FleetOwner on October 28. Diesel and gasoline are now telling two different stories at the same pump: the fuel that families burn is getting slightly cheaper, while the fuel that moves the country's freight keeps getting more expensive.

The regional map: Midwest jumps most, West Coast stays dearest
The Midwest recorded the largest regional weekly increase, rising 13 cents to $6.480 a gallon, FleetOwner reported from the EIA data. Rocky Mountain diesel rose 10 cents to $6.521, East Coast diesel rose 10 cents to $6.079, and Gulf Coast diesel — normally the cheapest in the country — rose 5 cents to $5.951.
The West Coast was the only region to fall, dropping 7 cents to $7.329 a gallon, and even after that fall it remains by far the most expensive diesel in America. Excluding California, West Coast diesel dropped 5 cents to $6.614 — still above the national average, and a reminder that California's truckers, including the large Punjabi owner-operator community of the Central Valley, continue to pay the country's highest fuel bills.
Why diesel is not following gasoline down
AAA, whose national diesel average matches the EIA's $6.352 figure, said in a recent release cited by FleetOwner that gasoline's drop is being driven by the transition to winter-blend gasoline, which is cheaper to produce, while high crude-oil prices are preventing steeper declines at the pump. Crude is nearing $100 a barrel amid instability in the Strait of Hormuz, AAA said, and this month is poised to set a record as the most expensive October ever for gasoline prices, following similar records in August and September.
Diesel has no winter-blend relief of the same kind, and it is priced off the freight economy as much as off crude: when trucking demand, heating-oil season and tight refining capacity collide, diesel holds its premium. FleetOwner noted that Strait of Hormuz disruptions and elevated crude prices continue to influence U.S. fuel costs, and President Donald Trump, in a Fox News interview on October 25, again threatened action against Iran over the strait, saying it was 'getting to be decision time' on whether to make a deal or 'finish it off' — remarks reported by FleetOwner as part of the market backdrop, not as a price forecast.
What the survey evidence says fleets are feeling
A survey released October 28 by Geotab, conducted by Endeavor Business Intelligence, found that more than four out of five respondents — 82% — said their organisation's operating costs have increased over the past 12 months, and fuel was the most frequently cited cause, named in 31% of responses. The survey collected 497 qualified responses from trucking professionals between August 20 and October 6, 2026, with an overall margin of error of plus or minus 4.4 percentage points.
Geotab's own connected-vehicle analysis, cited in the same release, found that commercial vehicles idled for an average of 1 hour 25 minutes per driving day, using 0.95 gallons of fuel while idling, while the highest-idling 10% of vehicles idled for more than three hours and used more than 2 gallons a day. At $6.352 a gallon, that idling alone is roughly $6 a day for an average vehicle and more than $12 a day for the heaviest idlers — money burned without moving a single mile of freight.
At $6.352 a gallon, a 120-gallon fill costs about $762. A year ago, at roughly $2.63 less per gallon, the same fill cost about $446. The difference — more than $300 a fill — comes straight out of the same load revenue, before insurance, maintenance, truck payments or broker fees.
Impact on Punjabi and diaspora truckers
Punjabi owner-operators and small fleet owners are concentrated on exactly the corridors where diesel bites hardest: California's I-5 and Highway 99 through the Central Valley, I-80 across the Sierra and the Midwest, I-10 and I-45 in Texas, and the I-95 corridor in the Northeast. A West Coast price of $7.329 a gallon means a California-based driver starts every week hundreds of dollars behind a Gulf Coast competitor paying $5.951, on fuel alone.
The Geotab findings point to the responses fleets are actually using: tighter fuel-purchase controls, anti-fraud checks on fuel cards, route and idling discipline, and hunting for lower-cost fuelling locations. None of those measures changes the EIA headline number — they only decide how much of it each business absorbs.
Background, and what happens next
This week's release continues a year in which U.S. diesel has stayed far above its year-ago level — the Geotab release, citing the EIA, put the week-of-October-26 average at $6.35 a gallon, 71% higher than a year earlier. Federal emergency measures on fuel hauling remain part of the backdrop, and the next test of the trend is the EIA's next weekly release, due in the first week of November, which will show whether the Midwest-led rise spreads or the West Coast's decline was the start of a wider easing.
For drivers, the practical watch-list is unchanged: the weekly EIA number every Monday, crude's path around the Strait of Hormuz, and whether gasoline's winter-blend relief ever reaches the diesel pumps. Until it does, $6-plus diesel remains the single largest cost line in American trucking.
