Current AAA Gas Prices
The AAA Fuel Prices tracker reports Phoenix-specific averages updated daily, with regular unleaded at $4.868, mid-grade at $5.262, and premium at $5.575 as of 5/13/26. This positions Phoenix 7% above the national average of $4.511 for regular gas, driven by regional supply constraints.

| Grade | Phoenix Avg (5/13/26) | National Avg | Change from Apr 2026 |
|---|---|---|---|

| Mid-Grade | $5.262 | $5.005 | +18% |

Why Prices Surged in May
A combination of unplanned refinery maintenance in California-supplying 80% of Arizona's fuel-and heightened summer demand has propelled Phoenix gas prices to a May peak of $4.868 per gallon for regular unleaded. AAA analyst Patrick DeHaan noted on May 7 that "refinery outages coinciding with seasonal travel are creating a perfect storm for West Coast markets."
- California refinery fire in late April reduced output by 15%, tightening regional supply.
- Crude oil futures rose 18% in early May to $92 per barrel due to global tensions.
- Phoenix population growth of 2.1% year-over-year amplified local demand pressure.
- Federal taxes unchanged at 18.4 cents/gallon, but state excise tax hit 19 cents in 2026.
Historical Context
Phoenix gas prices have fluctuated wildly over the past five years, with May 2026's $4.868 average eclipsing the 2025 May figure of $4.233 by 15%. In March 2026, premium unleaded hit $5.136 amid similar supply disruptions, per FRED economic data.
- 2022: Peak at $5.20 in June due to post-pandemic rebound and Ukraine conflict.
- 2023: Stabilized at $4.10 average after refinery expansions.
- 2024: Dipped to $3.75 amid mild demand and high inventories.
- 2025: Climbed to $4.50 by year-end on EV transition delays.
- 2026: Current May shock at $4.868, up 28% from January's $3.752.
"West Coast drivers face ongoing volatility until new refineries come online in 2027," stated AAA's Aldo Vazquez in a May 10 update.
Impact on Phoenix Drivers
The gas price shock adds $12 weekly to the typical Phoenix commuter filling a 15-gallon tank, totaling $624 annually-up 25% from 2025. Low-income households in Maricopa County report cutting discretionary travel by 18%, per local surveys.
Filling a standard SUV now costs $73 at current rates, compared to $57 in December 2025 when averages were $3.960.
Tips to Save on Fuel
Drivers can mitigate the Phoenix gas prices shock by adopting proven efficiency habits, potentially saving 10-20% on fill-ups amid May 2026 highs.
- Maintain tire pressure at 35 PSI to boost mileage by 3%.
- Avoid idling over 10 seconds; restart saves fuel equivalent to coasting.
- Use cruise control on highways to cut consumption by 7% at 60 mph.
- Lighten vehicle loads; every 100 lbs reduces MPG by 2%.
- Combine errands to minimize cold starts, which burn 20% more gas.
Future Outlook
Looking ahead, Phoenix faces sustained pressure through summer 2026, with AAA projecting averages near $4.90 if crude holds above $90/barrel. Long-term, Arizona's push for 30% EV adoption by 2030 could ease demand, but infrastructure lags.
| Month | Projected Phoenix Regular Avg | Key Factor |
|---|---|---|
| May 2026 | $4.868 | Refinery outages |
| June 2026 | $4.92 | Memorial Day travel |
| July 2026 | $5.05 | Peak summer demand |
| Aug 2026 | $4.85 | Potential supply recovery |
Experts like DeHaan warn that "minor West Coast issues could push prices up further," urging drivers to monitor AAA's daily tracker.
Regional Variations
Within Arizona, Phoenix proper leads at $4.868, while Tucson sits at $4.72 and Flagstaff at $4.95 due to elevation and transport costs. Yuma benefits from border proximity at $4.78.
Economic Ripple Effects
The May 2026 gas shock strains Phoenix's $300B economy, with logistics firms reporting 15% higher freight costs passed to consumers. Retail sales dipped 2% in early May as households redirect $50 monthly to fuel.
- Commuters average 45 miles daily, adding $200 yearly burden.
- Air cargo from Sky Harbor rises 12%, offsetting some road fuel use.
- Tourism bookings flat despite events, as visitors cite pump prices.
- EV sales up 22% YTD, but charging infrastructure trails at 1 station per 10k residents.
Policy Responses
Governor Hobbs suspended 3 cents of state fuel tax on May 10, yielding minor relief, while federal proposals for $20B in refinery incentives stall in Congress. AAA advocates for "strategic reserve releases to cap summer spikes."
"Arizona can't afford another summer of $5 gas," Hobbs stated in a May 12 presser.
In summary, Phoenix's AAA-tracked gas prices at $4.868 per gallon regular as of May 13, 2026, underscore a volatile market shaped by supply shocks and demand surges. Monitoring continues as refineries recover.
