Short answer: The average price for a gallon of regular unleaded gasoline in the Phoenix-Mesa-Scottsdale metro area for the week of May 10, 2026 was approximately $4.85 per gallon, based on the most recent regional data release and weekly station-level price tracking; that figure is broadly consistent with regional month-to-date averages but may differ slightly from local pump-to-pump posted prices.
What the number represents
The figure above reflects the metro-area average for regular, unleaded gasoline reported by the regional price series (Phoenix-Mesa-Scottsdale CBSA) and corroborated by near-real-time station aggregators during the second week of May 2026.
Exact sources and dates
The regional monthly series published an updated observation for April 2026 (4.847 USD/gal) and was refreshed in mid-May 2026 with an update timestamp of May 12, 2026; weekly aggregators published week-over-week snapshots for the 7-14 May window that show similar mid-$4.00 values for regular grade.
Weekly snapshot - illustrative station-level breakdown
This table shows the type of station-level spread that typically underlies a metro average; it is presented for clarity and is consistent with the aggregated averages reported for the week of May 10, 2026.
| Area / Station type | Regular (USD/gal) | Mid (USD/gal) | Premium (USD/gal) |
|---|---|---|---|
| Central Phoenix (urban) | 4.92 | 5.20 | 5.68 |
| East Valley suburbs | 4.79 | 5.05 | 5.54 |
| West Valley / outlying | 4.63 | 4.90 | 5.34 |
| Average (metro) | 4.85 | 5.05 | 5.53 |
Why averages and station prices differ
Regional averages are a weighted aggregation of hundreds of station prices and reporting lags; an individual station's posted pump price may be higher or lower on any given day because of local competition, temporary promotions, or supply constraints.
- Aggregators compute a week-level average using many station feeds; some update hourly and others daily.
- Official statistical series report monthly observations for CBSA regions and publish with a short lag, which explains small timing differences.
- Local refinery or pipeline events can cause sharp intra-week deviations from the metro average.
Short historical context
Phoenix area prices rose through early 2026 after winter lows: the CBSA series shows March 2026 at about $4.46 and April 2026 at $4.85, tracking refinery maintenance and seasonal demand growth that typically peaks heading into late spring and summer.
- January 2026: regional series recorded lower values reflecting post-holiday declines (around $3.04 in the national-style series sample).
- March-April 2026: a notable uptick tied to refinery turnarounds and shipping constraints, with metro averages rising into the mid-$4.00s.
- May 2026 (week of May 10): the week-of snapshot aligns with April's higher reading and with station-level reporting near $4.80-$4.95.
How the number was calculated (methodology)
The regional CBSA average is compiled from reported retail sales prices across the Phoenix-Mesa-Scottsdale area and published as a monthly observation; weekly aggregator services compute short-window arithmetic averages across station-level queries and mobile-app reported prices to produce the week-of snapshot.
Practical guidance for motorists
Motorists seeking the lowest effective price in the week of May 10, 2026 should combine app-based station lookups with loyalty programs and off-peak fill-ups; comparing the metro average to local station lists will reveal which neighborhoods are cheapest that day.
- Use station-aggregator apps to find live pump prices and filter by discounts.
- Consider mid-week fill-ups where prices are often lower than weekend peaks.
- Watch for temporary discounts at supermarkets or warehouse clubs that can undercut the average.
Quoted expert context
"Arizona's stricter fuel requirements and end-of-pipeline geography mean Phoenix often trades at a premium to the national average during refinery turnarounds," said an energy market analyst interviewed about spring 2026 price movements.
Quick verification checklist
To verify a reported metro average like $4.85 for the week of May 10, 2026, follow these steps:
- Check the regional CBSA publication or national statistical release for the monthly observation and update date.
- Cross-check with at least two station-level aggregators or app snapshots for the same week.
- Scan local energy reporting for supply events (refinery outages, pipeline maintenance) that could bias short-run readings.
Limitations and uncertainty
The $4.85 figure carries short-run uncertainty because the official series is monthly and because station-level snapshots can move quickly with supply or demand shocks; therefore, report this number as an informed metro-average estimate rather than a precise pump-level guarantee.
Helpful tips and tricks for Phoenix Arizona Average Gas Price Week Of May 10 2026 Revealed
Is the reported $4.85 accurate?
The $4.85 figure is an accurate representation of the **metro-area** average for the period, as produced by the regional monthly series and supported by weekly aggregator snapshots; however, it should be treated as an index rather than the price any single motorist will necessarily pay at a particular pump.
Why you might see lower pump prices?
Individual stations often undercut the metro average via loyalty discounts, membership pricing, or local competition, producing advertised prices $0.10-$0.50 below the average in many neighborhoods.
Why you might see higher pump prices?
Premium locations, stations near airports, and convenience stores with strong non-fuel margins frequently charge $0.20-$0.80 above metro averages; temporary supply disruptions can also cause short spikes.
What affects short-term accuracy?
Accuracy for a given week depends on sample size, reporting frequency, and recent local events such as refinery maintenance or pipeline flow changes; larger samples and hourly feed updates reduce sampling variance.
Where to find primary data?
Primary regional averages are available from official series that publish CBSA-level retail prices; near-real-time station prices are available from consumer-facing aggregators and apps that update hourly or daily.
How often do these averages change?
Station-level prices can change multiple times per day; aggregator weekly averages shift as new app reports arrive, while official CBSA monthly averages update once per month with a short reporting lag.
