Arizonans recently experienced a significant 21-cent increase in gas prices over the course of a week 

This increase in gas prices in Arizona contrasted with the national average, which only rose by 5 cents during the same period 

Historically, Arizona has seen price increases while the U.S. average witnessed drops in gas prices 

As of September 19, the average gas price in Arizona was $4.607, while the national average stood at $3.880, according to AAA data 

Within a week, Arizona reported one of the largest gas price spikes in the nation, amounting to a 17-cent increase, according to AAA's weekly report. Minnesota had the highest increase at 32 cents 

Despite the increase, Arizona remained the seventh most expensive state in the U.S. for gasoline, with residents paying an average of $4.51 per gallon 

The national gas price average on Tuesday was 12 cents higher compared to the same time in 2022 

A decrease in gas demand has been noted as the fall season approaches, raising questions about the possibility of lower prices 

Gas prices in the U.S. increased by five cents due to rising oil costs, with oil reaching around $90 per barrel 

Despite decreased gas demand, high oil costs have prevented the usual decline in pump prices, with concerns about a global oil supply shortage contributing to elevated oil prices
