PHOENIX – While gas prices have soared in Arizona during the month of September, cheaper prices are on the way.
In the past month, fuel prices have climbed 24 cents per gallon on average in Arizona, but as refineries switch to a winter a blend from the summer blend with higher production costs, Arizonans will soon see cheaper prices at the pump.
The EPA requires gas retailers in Maricopa County and portions of Pinal and Yavapai Counties to sell these summer blends from June 1 through Sept. 30. The switch is made in order to reduce pollutants.
In Arizona, the average price for a gallon of regular gasoline is at $3.57 as of Thursday. The price dropped two cents since last week, according to AAA’s Fuel Prices database. In Phoenix, the price is significantly above the statewide average at $3.85 per gallon.
Arizona ranks as the state with the seventh-most expensive gas in the nation. The national average for a gallon of regular gasoline fell to $3.15, a five-cent drop since last week.
Gas prices are beginning to rise again, but there’s a seasonal shift on the horizon: winter blend fuel is coming soon. As Bruce St. James puts it, it’s “the pumpkin spice of gasoline.” 🚗 @OutspokenKTAR pic.twitter.com/2jHA6fdQ82

Everyone is gwtting kicked by the big Republican taxes -- all which started with Trump taking office. He promised to cut energy in half -- reality is double-digit increases.
Jarred Kushner, Trump's son in law (who's felon father was pardoned by Trump) runs a $500milliom middle eastern investment fund since leaving the WH. Trump is best pals with Saudi Arabia and the other countries that brought us 9/11. Why can't he make a deal?
Why can't he fix these wars?
Why did we sign on for $6trillion more in debt this year, so far?
What Republicans voter is doing better today than they were last year?
I would certainly hope so. Gas is pushing 4.00, groceries are outrageous and these tariff taxes have caused everything else to go up. Sure could use some help on the economy, healthcare and education but seems taco is too busy fighting with comedians and escalators
The President prioritizes profits (and Raping Kids on Epstein Island) over our citizens/consumers.
The system is working as laid out by the Heritage Foundation in Project 2025. Trump put the authors of each chapter in charge of their respective departments.
The key right now is to be rich. It's a bad time to be a consumer but a great time to be flush with capital. The more resources get squeezed -- housing, food, energy, medical, water -- the more you can profit per-unit. By letting the rich control their own markets, they can restrict competition and, in turn, raise prices which leads to high stockholder profits.
