Gas Hits $4.31 National Average; Diesel Sets Records

American drivers are paying $4.31 a gallon for regular gas on average, with multiple states now over $5, as two wars scramble global energy supply.

Diesel is the bigger shock: it remains at a record high nationally, and Cleveland.com reported unleaded is already $6 a gallon in California as of Sept. 14, 2026.

AAA told WPXI in Pittsburgh the run-up follows volatility in the Strait of Hormuz, which has pushed crude oil back into the $100-per-barrel range for the first time since July.

The Numbers

Michigan posted the largest weekly jump of any state, up 32 cents a gallon, according to The Center Square. Wisconsin rose more than 29 cents to $4.09, trailing only Michigan and Utah for the biggest week-over-week increase.

Virginia's regular average climbed nearly 18 cents in a week to $4.14 on Monday. Pennsylvania gas jumped more than 20 cents. Florida moved up by double digits to more than $4, the Miami Herald reported.
