Arizona gas prices are continuing to fall. Here's what to know and where to fill up

Arizona gas prices continued to decline, registering a nine-cent drop in average price per gallon since last week, which is the fourth-largest decrease in the country.

On Thursday, AAA reported that Grand Canyon State residents were paying about $3.47 per gallon on average at pumps across the state. Arizona's consistent price drops have outpaced how much the U.S. average has declined over the past few months, allowing the state to make up considerable ground versus its national counterpart, now at $3.24.

Since Nov. 2, AAA's first report for the month, Arizona markets have shaved 44 cents off its statewide mean, while the national average has only fallen by 20 cents. With just a 23-cent difference in price, Arizona is entering a more reasonable middle ground experts have been predicting.

In turn, Arizona's rank among the top 10 most expensive states in the country has also fallen, placing it outside the infamous group.

Shifting the focus toward the national scene, prices as a whole only shed 2 cents since the week prior. According to AAA, the reasoning behind the shallow dip is due to a rebounding cost of oil, slowly making its way back to $80 per barrel.

“The current streak of daily pump prices either falling or staying flat started on September 19,” AAA spokesperson Andrew Gross said in the group's weekly release. “It appears this run is in jeopardy, and we may see prices edge a bit higher. But if the cost of oil eventually hits reverse and dips again, pump prices will likely follow suit."

Recently released data from the Energy Information Administration, as cited by AAA, saw demand for the resource take a dive, going from 8.48 million barrels per day to 8.21 million. Total domestic stocks rose as a result, jumping up by 1.8 million barrels of crude oil to settle at 218.2 million barrels.

Total domestic commercial crude inventories saw a 1.6 million barrel of crude oil spike, bringing its tally to 449.7 million.

Wednesday's end to the formal trading session had West Texas Intermediate grow its price by $1.45, for a total of $77.86.

Thursday's listed national average of $3.24 is 26 cents less than it was in October as well as this time last year.
