September Pump Prices Start at Historic High

Phoenix, Sept. 6, 2012. The price of gasoline has risen swiftly over the last month. In fact, after climbing more than 40 cents since early August, this is the most Arizona motorists have paid for fuel in September, according to AAA. This week, the statewide average rose 9.1 cents to $3.699 per gallon, while the national average shed 0.1 cents to $3.823 per gallon. 


A week after Hurricane Isaac moved through the Gulf of Mexico, production has begun to resume in the refining region. Even though the storm caused little damage, there are still lingering effects from delays in refineries coming back online.


“Over the last five weeks, Arizona motorists have seen the cost of fuel surge to start September at historic highs,” said Linda Gorman, director of communications and public affairs for AAA Arizona. “However, now that the summer driving season has ended, refineries are reopening, and the switch to our less expensive winter blend of fuel is approaching, the short-term outlook appears promising.”


Tucson and Flagstaff hold the low and high state fuel averages at $3.616 and $3.827 per gallon, respectively. Colorado and California hold the low and high price extremes for the lower 48 states at $3.578 and $4.169 per gallon, respectively.

*The BTU-adjusted price of E-85 is the nationwide average price of E-85 adjusted to reflect the lower energy content as expressed in British Thermal Units. The BTU-adjusted price is calculated and displayed as part of AAA's Fuel Gauge Report because according to the Energy Information Administration, E-85 delivers about 25 percent fewer BTUs by volume than conventional gasoline. Because "flexible fuel" vehicles can operate on conventional fuel and E-85, the BTU-adjusted price of E-85 is essential to understanding the cost implications of each fuel choice for consumers.


AAA’s Fuel Gauge Report includes data from gasoline stations in every Arizona community. Local prices in some communities might be higher or lower than the averages shown here. This service is updated daily by the Oil Price Information Service (OPIS) with average national, state and local prices for gasoline, diesel and E-85. Every day, more than 100,000 stations are surveyed in cooperation with Wright Express for unmatched statistical reliability.
