Drivers filling up on the West Coast are paying much more at the pump than those in the nation’s central states, according to the latest price data from AAA and GasBuddy. Gas prices have soared since the war in Iran.

California continues to lead the nation with the highest average price for regular unleaded gasoline at about $5.93 per gallon, nearly double the cost in parts of the Midwest and South.

Oklahoma, Kansas, and North Dakota rank among the states with the lowest regular gasoline prices, averaging about $3.27 to $3.45 per gallon as of April 8.

That wide price gap also extends to diesel fuel. In California, the average diesel price is about $7.68 per gallon, while several states outside the West Coast report diesel prices well below $5 per gallon.

AAA’s daily national average for regular gasoline stands above $4.11 per gallon, marking a significant increase from recent months. The national average has climbed from under $4 per gallon in early April to above $4.10 by April 6.
According to an Investopedia analysis, gas prices vary across the United States because of differences in taxes, production, and delivery infrastructure. Environmental regulations, such as California’s requirement for cleaner-burning gasoline, also contribute to the state’s persistently higher fuel costs.

GasBuddy data highlights weekly and monthly price trends. Patrick De Haan, GasBuddy’s head of petroleum analysis, said on April 6 that continued volatility in global oil markets could push averages higher in the coming days.

“Gasoline prices are poised for another jolt this week, with many inland states — including the Plains, Great Lakes, and parts of the Rockies — likely to see sharp increases as last week’s surge in wholesale costs has yet to be fully passed through to consumers,” De Haan said.

“In addition, some price-cycling markets could also see another round of increases. As a result, the national average could rise by double digits, potentially reaching the $4.20 to $4.35 per gallon range in the days ahead,” he warned, adding that diesel prices “sit just 25 cents away from setting a new all-time record.”

According to De Haan, the trajectory of fuel prices remains highly uncertain and depends largely on the reopening of the Strait of Hormuz. “Until that occurs, the risk of further increases remains firmly in place,” he said.
