Sunday Prices Lead Nationwide GasBuddy’s year‑long analysis of daily statewide averages shows Sunday delivers the lowest per‑gallon cost in the majority of states, including California, Texas, Florida and New York [1][2][3]. The pattern holds despite analysts projecting a five‑year low for overall gasoline prices in 2026 [1]. Drivers who fill up on Sunday can lock in the most favorable rates before the weekly price climb begins.

Midweek Days Register Highest Rates Wednesday and Thursday emerge as the costliest days in many Southern and Midwestern markets, while Thursday tops the chart in parts of the Northeast and West Coast [1][2][3]. Across the country, Wednesday‑Friday prices consistently exceed weekend rates, creating a predictable mid‑week peak that pushes costs up by several cents per gallon [1][2][3].

State‑Specific Cycle Patterns Offer Larger Savings In markets such as Michigan, Indiana, Ohio, Florida, Texas and portions of the West Coast, prices spike sharply on a set day then decline gradually, a “price cycling” effect [2][3]. GasBuddy estimates that waiting five to seven days after a spike can shave $0.15‑$0.45 off each gallon in these states [2][3]. This timing advantage dwarfs the modest 4‑9‑cent savings achievable by simply choosing Sunday in non‑cycling regions [1].

Exceptions to Sunday Trend Identified Alaska, Delaware, Indiana and Ohio record Monday as the cheapest day, while Montana’s lowest rates fall on Tuesday [2][3]. Kansas, Pennsylvania, South Dakota and Wyoming break the Sunday rule entirely, with Saturday offering the best prices [1][2][3]. These outliers illustrate that regional tax structures, refinery capacity and local blend requirements can overturn the national rhythm.

Consumer Guidance Emphasized by GasBuddy The company urges motorists to consult its app before refueling and to approach Tuesdays and Saturdays with caution, as those days often carry higher prices [2][3]. For drivers outside cycling markets, shifting fill‑ups from the most expensive mid‑week days to Sunday can save 4‑9 cents per gallon [1]. Combining app‑based price checks with strategic timing maximizes potential savings across all regions.
