Gas Prices in Tempe, AZ Today
Tempe drivers are paying around $3.95–4.15 per gallon for regular unleaded in late March 2026, tracking close to the Arizona state average of $4.02. As a college city wedged between Phoenix, Scottsdale, Mesa, and Chandler, Tempe has more gas station options per square mile than most similarly-sized cities — but the prices vary dramatically depending on how close you are to Arizona State University and the tourist-heavy Mill Avenue district versus the freeway-adjacent commercial corridors on the city's edges.
Mill Avenue and the Campus Premium
Stations within walking distance of ASU's Tempe campus and along Mill Avenue consistently run at the top of the local price range. The customer mix in that area — students without cars who occasionally borrow one, visitors to the stadium and concert venues, and bar-district traffic — is less price-sensitive and less likely to drive five minutes for a cheaper station. Several stations in the 85281 and northern 85282 ZIP codes charge 20–30 cents above what you'd pay on the southern or western edges of Tempe.
This is a classic urban university pricing pattern. The same dynamic shows up around USC in Los Angeles, Ohio State in Columbus, and UT Austin in Texas.
Costco on Priest Drive
The Costco fuel center on Priest Drive in south Tempe is the most reliable low-price option in the city. It consistently prices 20–30 cents below the local average, and membership pays for itself in gas savings alone if you're filling up once a week at Arizona prices. The station is positioned in the 85284 ZIP — southern Tempe near the Chandler border — which is already one of the more competitive zones in the city. That Costco at that location in that ZIP code is about as good as it gets for Tempe drivers.
Freeway Interchange Advantage: Lots of Options
Tempe is one of the most freeway-dense cities in the Phoenix metro. I-10 cuts through the northern edge, US-60 (the Superstition Freeway) runs east-west through central Tempe, and Loop 101 (the Price Freeway / Red Mountain Freeway) marks the eastern boundary. That many interchanges means a lot of stations competing for commuter traffic, and the off-ramp stations along Price Road and Baseline Road genuinely compete with each other.
The stations along the Rural Road corridor — which runs north-south through central Tempe — offer particularly consistent pricing because they serve daily ASU commuters who know the area well and will go to the cheapest option.
Where to Find the Cheapest Gas in Tempe
Search by ZIP code:
- South Tempe / Chandler border / Priest Dr area — 85284 — Costco fuel center here, most competitive zone in the city
- Southeast Tempe / US-60 corridor — 85283 — suburban residential with Price Road and Baseline commercial access
- Central Tempe / Rural Rd corridor — 85282 — mixed; stations south of Broadway are better priced than those near campus
- North Tempe / ASU adjacent — 85281 — campus premium, avoid if you have a 5-minute alternative
- West Tempe / I-10 exits — 85285 — freeway-adjacent, varies; off-ramp stations are pricier
- Navigating to the cheapest station is easier with a phone mount — hands-free directions while you drive.
- A tire pressure gauge is one of the cheapest ways to improve fuel economy — underinflated tires cost you up to 3% at the pump.
Summer Blend Transition
Like all Phoenix-area cities, Tempe switches to a summer reformulated blend in June. Prices typically rise 5–10 cents in late May as the transition hits. If you're filling up in late March or April, you're catching the tail end of the cheaper winter blend window.
