As of September 15, 2025, gasoline prices have surged, positioning Washington drivers with the highest gas prices nationally. A gallon of regular gas in Washington averages $4.658, reflecting an increase from previous weeks and months, while California's prices have risen but remain slightly below Washington's. Factors contributing to this price spike include scheduled and unscheduled refinery maintenance, disruptions in pipeline operations, and recent tax increases. The state's gas tax, which increased in July 2025 and will continue to rise annually, places additional financial strain on consumers. Furthermore, gasoline refinery closures in California have exacerbated the situation, as the West Coast states heavily rely on California's fuel production to meet demand. Retail prices are now being influenced significantly by wholesale price escalations due to refinery issues, and the overall economic environment is affected by potential international tensions that may further constrain oil supply chains.
