Gas prices have been rising the past few weeks and are expected to peak by June at around $2.70 per gallon for regular—about 70 cents above last year’s price, according to AAA.
Meanwhile, prices at any given moment vary significantly even among stations just a few miles apart. We visited six stations between Happy Valley Road and Anthem on Thursday, April 13. Prices varied 15.7 percent between the cheapest and most expensive stations. The survey revealed a similar spread to one conducted April 4.
Note: The three Circle K stations in Anthem often if not always have the same prices, as the did on the day of our survey.
Gas prices trend higher in summer because the industry switches to a more expensive summer-blend gasoline, explained Michelle Donati, a spokesperson for AAA Arizona. Summer blend is less volatile, so it evaporates less in the heat. This helps vehicles run better on hot days and produces less pollution.
While our survey is just a snapshot in time, the differences between stations are similar to the same spot check we did two weeks prior.
