Rising diesel prices squeeze Fresno food trucks, force tougher choices

Diesel prices are pinching Fresno food trucks at the exact point where every gallon matters, pushing operators to rethink fuel runs, menu pricing and even which events are worth the drive. With California diesel near $8 a gallon, AAA put the statewide average at about $7.43 and Fresno at $7.48, while regular gasoline in Fresno was about $6.06.

For Jose Perez, who owns Yohabachi, the increase is not an abstract market number. His business depends on a diesel truck to tow the food trailer, haul supplies and keep the operation moving from one site to the next. Perez said filling up that truck had doubled in a matter of months, from about $150 to roughly $320, a jump that lands hardest on mobile food businesses because fuel is part of nearly every workday.

That pressure is forcing the kind of calculation that determines whether a food truck can stay competitive in Fresno County. Perez said he has raised prices a little, but not enough to chase away customers. That balancing act is now central to the economics of operating a truck in a market where customers are price-sensitive and owners cannot absorb higher costs forever. If fuel keeps climbing, the pressure can spread beyond the pump to ingredient runs, delivery timing, staffing schedules and the number of events a truck can realistically serve.

The mechanics of diesel pricing help explain why the squeeze has been so sharp. The Energy Information Administration says retail diesel prices are built from crude oil, refining, distribution and marketing, plus taxes, and that crude oil has historically been the largest component of U.S. diesel prices. California adds its own layer of cost, including a diesel fuel tax that rose to 46.6 cents per gallon effective July 1, 2025, along with the state’s Low Carbon Fuel Standard, which is designed to cut petroleum dependence and expand lower-carbon alternatives.

The surge has also been building for weeks. California diesel averaged $7.42 in April 2026, up from $6.321 in March and $4.78 in April 2025, a year-over-year increase of 55.23 percent. That kind of move helps explain why Fresno food truck owners were already feeling the pinch in late March and absorbing fuel costs rather than immediately passing them on.

For Fresno County, the ripple effects extend well beyond the truck itself. Food trucks are part of the region’s everyday dining scene, from parks and pop-up events to fairs and neighborhood gatherings, and higher diesel prices can mean higher lunch prices, fewer routes and tougher choices for the smallest operators trying to stay on the road.
