Gas Prices in Gilbert, AZ Today

Gilbert drivers are paying around $3.90–4.05 per gallon for regular unleaded in late March 2026, slightly below the Arizona state average of $4.02 in many parts of town. Gilbert has been the fastest-growing city in Arizona for several years running, and that growth dynamic directly affects gas prices in a way that most fast-growth markets experience: new station construction, aggressive promotional pricing from new retailers trying to build customer bases, and genuine competition among chains for market share in freshly developed corridors.

New Development, New Competition

Gilbert's rapid expansion southeast of the Phoenix metro has produced a specific retail phenomenon: newly opened stations in developing areas price aggressively to attract customers and build brand loyalty before a surrounding neighborhood fully populates. This is the inverse of what happens in mature urban markets where established stations have locked-in customer bases.

Along the Power Road corridor, the Higley Road commercial zone, and the newer development pushing south toward the San Tan Valley border, you'll find stations that have been open less than two or three years and are still competing for market share. Those stations tend to run at the lower end of local pricing. As the surrounding residential areas fill in and customers become habitual, that pricing pressure gradually relaxes, but for now, Gilbert's growth edge is your bargain edge.

The San Tan Village and Crossroads at Cooley Station Effect

The commercial zones around San Tan Village Mall and the Crossroads at Cooley Station retail development in eastern Gilbert generate high traffic that supports a cluster of competitive stations. High-volume retail anchors attract fuel stations that compete for the same customer base, and stations near those anchors price accordingly. The 85295 and 85296 ZIP codes cover much of this commercial corridor.

Costco has a location in the Gilbert/Chandler border area that serves the east Valley extensively. Warehouse club pricing here is consistent with what you'd expect: 20–25 cents below the local street average on most days.

Phoenix Summer Blend: Plan Ahead

Gilbert, as part of the Phoenix metro, switches to a reformulated summer gasoline blend on June 1. The transition adds roughly 5–10 cents per gallon as refineries produce the more expensive low-volatility blend required for Valley air quality standards. The window between now (late March) and late May is a good time to fill up if you're running low, before the seasonal premium kicks in. Gilbert's new-station competition helps, but even the most aggressive stations can't offset a statewide blend-driven cost increase.
