Gas prices in Phoenix, AZ

About gas prices in Phoenix, AZ

Phoenix operates inside Arizona's Cleaner Burning Gasoline (CBG) zone from November through March, which adds 5 to 10 cents per gallon during winter. The state has no in-state refining capacity. All gasoline sold in Phoenix arrives via two pipelines: the Kinder Morgan East Line from El Paso and the West Line from Los Angeles. When either pipeline is constrained (which has happened multiple times over the past decade), Phoenix retail spikes within days and recovery can take weeks. Arizona state gas tax is one of the lowest in the country at 18 cents per gallon. Phoenix drivers willing to fill up in West Valley suburbs (Glendale, Surprise, Goodyear) typically save 10 to 18 cents per gallon versus East Valley and Central Phoenix pricing. Costco locations in Avondale, Goodyear, and Surprise, Sam's Club locations along the Loop 101, plus Fry's Food (Kroger's Arizona banner) and QuikTrip stations across the metro typically post the lowest pricing most weeks.
