As is customary for the last three weeks, the national average price for a gallon of regular gas fell again on Friday, dropping to $4.108, according to AAA. The string of decreases began after the Memorial Day weekend holiday, traditionally recognized as the start of the summer driving season — and, subsequently, the start of increases in fuel costs. However, the current military conflict between the U.S. and Iran has disrupted the traditional gas market and caused significant price fluctuations since the beginning of March. 

Over the last three weeks, those fluctuations have benefited consumers. The three weeks prior, not so much. It’s been a whirlwind of gas price changes over the last few months, and no one seems to be sure what is next, as uncertainty around the Iranian conflict and hostilities in the Strait of Hormuz directly correlate with the national average price for a gallon of regular gas. Fuel costs have been quite volatile this spring. The recent three-week decline was preceded by days of rising costs, culminating in the record high for 2026 of $4.564 on May 21.
