Valley gas prices fell 13 cents a gallon this week to an average of $4.51 a gallon as the transition to winter blend of gasoline is underway according to AAA Arizona.
While the winter blend is cheaper to produce, higher crude oil prices and continuing instability in the Middle East are preventing prices from falling more.
“While gas prices continue to fall at the pump, this month is poised to set a record as the most expensive October ever for gas prices,” said David Caltabiano, spokesperson for AAA Mountain West Group late Thursday. “It follows similar records set in August and September of this year.”
