Finding cheap gas in Phoenix (85031)
Maryvale anchors 85031, a dense, compact slice of West Phoenix that was one of the Valley's first big postwar subdivisions and remains one of the most populous square-mile areas on this side of town. The high housing density and working-class character translate into strong, steady fuel demand spread across the main arterials.
Indian School Road, Thomas Road, McDowell, and the 35th, 43rd, and 51st Avenue corridors carry most of the traffic and most of the stations. With so many pumps competing in a tight footprint, the busy crossings here often post some of the more affordable prices on the west side, a few stations almost always within sight of each other, so there is rarely a need to go far to find a cheaper option.

How to save more on gas in Phoenix
1. Use warehouse clubs
Costco and Sam’s Club typically price 15-25 cents per gallon below nearby stations. Membership pays for itself within a few fill-ups.
2. Fill up early in the week
Stations often raise prices Thursday for weekend demand. Fill up Monday through Wednesday to avoid the lift.
3. Keep tires properly inflated
Properly inflated tires improve fuel economy by up to 3 percent at current prices. Check pressure once a month.
4. Check back tomorrow
Prices can shift 10-20 cents overnight during volatile markets. A quick check before you leave home avoids paying yesterday’s spike.
5. Pay cash at split-pricing stations
Stations with cash and credit split pricing typically save an average of 10 cents per gallon when you pay cash.

About gas prices in Arizona
Arizona's gas tax is roughly 18 cents per gallon, among the lowest in the country, and the state benefits from short pipeline distances to Los Angeles and El Paso refineries. The Phoenix metro requires reformulated gasoline (CBG, the Cleaner Burning Gasoline blend) from May through September to meet ozone standards, which usually prices about 5 to 10 cents above the rest of the state. Tucson, Flagstaff, and Yuma typically run noticeably cheaper. Costco, Sam's Club, Fry's Food (Kroger), and QuikTrip lead on value across Phoenix, Tucson, and Flagstaff metros.
