Gas Prices in Peoria, AZ Today
Peoria drivers are paying around $3.95–4.10 per gallon for regular unleaded in late March 2026, near the Arizona statewide average of $4.02. Arizona pays more than the national average of $3.91 primarily because of its distance from Gulf Coast refineries — fuel arrives via pipeline from California and Texas refineries, and that transportation cost shows up at the pump. Peoria's northwest Phoenix location means it doesn't carry the premium of inner-loop Phoenix stations, but it's not as cheap as some far-outlying desert markets either.
Spring Training and the February–March Price Effect
Peoria hosts the Peoria Sports Complex, the spring training home of the San Diego Padres and Seattle Mariners. The facility runs from mid-February through late March, drawing large crowds to the northwest Phoenix metro for six weeks. That influx of out-of-town visitors — many of them unfamiliar with local prices and not motivated to shop around — gives nearby stations reduced competitive pressure during the spring training window.
Stations within a mile or two of the Sports Complex (in the 83rd Avenue corridor and the Bell Road / Peoria Avenue area) tend to run 8–12 cents above what you'd pay on the northern or western edges of the city during February and March. This isn't a massive effect, but it's consistent. By late April, when the crowds leave, those same stations come back down to market rates.
Arizona's Phoenix Blend Requirement
The Phoenix metro area — which includes Peoria — requires a special low-volatility reformulated gasoline blend from June 1 through September 15 each year to control ozone formation in the Valley's heat. This summer blend costs more to produce and is not interchangeable with fuel from other Arizona regions. Prices typically see a 5–10 cent jump in late May as refineries switch to summer-blend production and distributors burn through conventional inventory.
Spring (March–May) is therefore one of the cheaper windows to fill up before the summer blend premium kicks in.

I-17 and Loop 101 Interchange Stations
Peoria's main freeway access — Loop 101 (Agua Fria Freeway) running north-south and the US-60 connection to the east — creates predictable premium zones. Stations directly at freeway exits on 101 tend to run above the local average because they catch travelers and commuters who aren't comparison-shopping. The best prices are consistently found a mile or more off the freeway on surface streets.
