Diesel at $6.35 Costs Owner Operators About $1.06 a Mile in Fuel Alone

Record diesel has stopped being a headline for owner operators and turned into a line on the settlement sheet. The latest EIA reading is $6.352 a gallon, and at 6 miles per gallon that is $1.06 of fuel in every mile you run.

That is the number to plan around, and it is about 74 percent more per mile than the same truck burned at last year's average price.

Fuel looked like the tame cost in 2025. ATRI's numbers put it at about 48 cents a mile for the average fleet, when diesel averaged $3.66 a gallon. After a dip earlier this month, the pump is climbing again. It sits just under the September record of $6.53, and the rate on your load board has not kept pace. That gap, not the sticker price, decides whether a week pays.

Here is the math at 2,500 miles a week. I run a 2009 Freightliner Columbia with a Detroit engine, and every owner operator should know their own mpg from fuel receipts, not from a brochure. So run it three ways, then put your own numbers into the trucking fuel cost calculator.

Assumes 2,500 miles a week and the EIA national average for October 26, 2026. Your lanes and fuel stops will differ.

At 6 miles per gallon, every extra dollar at the pump costs about $417 a week. The $2.69 jump since last year's average works out to roughly $4,900 a month at that pace, before you buy a single tire.

It is already thinning the field. Dave Turner, a Nebraska company driver of more than 25 years, told KETV that seven of his 13 independent trucker friends have parked their trucks and found other work.

The usual answer is that fuel surcharges cover it. They cover some of it. On FreightWaves, Julie Van de Kamp noted that surcharges do not pay for deadhead and repositioning miles, and Craig Fuller noted that fuel is due within two to three days while freight can take 60 to 90 days to pay. That timing gap is where a small carrier on its own authority gets squeezed, even when rates are better than last year.

Do not wait for relief. Land Line reported that AFS Logistics CEO Andy Dyer expects fuel to keep transportation costs elevated for the foreseeable future, and that AFS says surcharges will not fall materially even if crude eases. Pull your last 30 fuel receipts tonight, work out your real mpg, and price every load against your true cost per mile, not the 48 cents ATRI averaged for fleets last year. The cost per mile calculator adds in the rest.
