Gas Prices in Phoenix
Phoenix offers competitive gas prices driven by strong QuikTrip and Fry's Fuel Center competition across the sprawling Valley of the Sun. Arizona's low 18¢ tax keeps base prices moderate; the main price variable is distance from the California pipeline connections that supply most of the state's fuel.
Prices at individual stations can vary by 5–15 cents within the same city depending on brand, location, and local competition. Use apps like GasBuddy to find the cheapest station near you in Phoenix.

Costco in Tempe, Gilbert, and Chandler offers excellent prices for members. Suburban areas in the East Valley (Mesa, Chandler) often run cheaper than central Phoenix.
