California gas averages $5.40 a gallon ahead of July 4, up $0.83 from a year earlier
Ahead of July 4, California’s average gasoline price has climbed to $5.40 per gallon, up $0.83 from $4.57 a year ago, according to the American Automobile Association. Nationwide prices have also risen, with the national average at $3.84 per gallon, as the war in Iran has tightened global oil supplies. California’s increase in its gasoline excise tax to 63.4 cents per gallon on July 1, along with limited local refining capacity and stronger seasonal demand, has added to the state’s outsized jump. Prices in areas including Los Angeles, San Francisco and Mono County are running well above the national average.
