Finding cheap gas in Phoenix (85029)
Northwest Phoenix along the Interstate 17 corridor was for decades organized around Metrocenter, the landmark mall that opened in 1973 and was demolished in 2020. The 64-acre site near I-17 and Dunlap is now being rebuilt as The Metropolitan, a large mixed-use redevelopment that is reshaping how traffic and retail flow through the area.
Peoria Avenue, Cactus Road, and Dunlap Avenue cross the freeway here, and the stations near those I-17 interchanges handle the bulk of the volume. The high-traffic corners along the frontage usually price more aggressively than the pumps tucked into the surrounding apartment grids.
Phoenix prices respond to West Coast refinery swings, so the spread between stations can widen quickly when supply tightens. Comparing the I-17 frontage stations against those on the inner mile roads is the reliable way to find the low number.

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.
