Weekly Trends
- Spokane regular gas rose +$0.29 (+5.8%) last week to $5.31 as of May 4.
- Diesel dipped -$0.02 (-0.3%) to $6.54, bucking the gasoline surge.
- Year-over-year, regular jumped +$1.45 (+37.7%), matching national crude spikes.

These shifts stem from refinery maintenance in Anacortes and PADD 5 imports tightening supply. AAA tracks show volatility tied to West Coast logistics.
What's Driving the Gap?
The disparity between $3.29 Costco lows and $5.31 averages exceeds 60%, fueled by membership bulk buying versus retail markups. High-volume sellers like Costco negotiate lower wholesale rates from suppliers like Chevron and Shell.
"We're seeing unprecedented spreads due to targeted promotions and inventory strategies-drivers can save 38% by shopping smart," says AAA Northwest analyst Maria Johnson on May 7, 2026.
Crude oil futures, up 12% since April, amplify this as Brent crude nears $92/barrel amid geopolitical tensions in the Strait of Hormuz. Local taxes at 49.4 cents/gallon add steady pressure.
Historical Context
- In December 2025, a price war at Hamilton Market and Mobil dropped regular to $0.58-$0.99 for hours, drawing lines blocks long.
- April 2025 saw Spokane at $4.065, up from $3.96 weekly, per early AAA reads.
- March 2026 averaged $4.29, with +10.7% weekly jumps signaling spring surges.
- May 2026 marks the metro's priciest May ever, eclipsing 2022's $4.95 peak.
- Diesel's 54.3% annual rise outpaces gas, hitting truckers hardest.
Past wars like 2025's holiday gimmick show stations can slash 50% temporarily, but sustained highs reflect 15% global demand growth post-2025 recovery.
Factors Influencing Prices
Supply chains dominate: Washington's reliance on California refineries, down 8% capacity since 2024, creates bottlenecks. Summer blend transitions by June 1 add 10-15 cents/gallon.
- Oil prices: WTI at $89.50/barrel, +11% monthly.
- Taxes: 28 cents federal + 21.4 cents state excise + local fees.
- Demand: Memorial Day travel up 3% YoY per DOT forecasts.
- Inventory: PADD 5 gasoline stocks -5.2 million barrels WoW (EIA May 8).
President Trump's 2026 energy policies, boosting domestic drilling by 22%, aim to ease this long-term, but West Coast lags East Coast drops.
