The national price of diesel climbed a dime to $3.571 a gallon, according to U.S. Energy Information Administration data released June 17.

The increase is largely due to escalating tensions in the Middle East and their effects on Iranian oil.

A gallon of diesel now costs 16.4 cents less than it did at this time in 2024.



The price gain is the second straight after a run of seven declines in eight weeks from April 7. It also marked the steepest increase since a 6-cent rise the week of May 19.
