The national average for regular gasoline stands at $4.34 per gallon as of October 12, 2026, according to AAA. While this marks a slight easing over the past month—driven by crude oil pulling back from its early-May peak—prices remain well above year-ago levels. Diesel is also feeling the pinch, with the national average nearing $6.25 per gallon, reflecting persistent pressure on distillate markets. The current averages for mid-grade, premium, and E85 are also elevated, underscoring that the reprieve at the pump is modest at best.

California continues to lead the nation in pain at the pump, with prices significantly higher than the national average. The state’s premium is largely due to the nation’s highest state gas taxes, a unique cleaner-burning CARB fuel blend that few refineries produce, and limited pipeline supply that isolates the state’s market. Among the large states the EIA tracks weekly, California is typically the most expensive on the mainland. This structural premium means that even when national prices decline, California drivers often see less relief.

The data comes from OilGasPrices.com, a premium, exact-match energy data domain currently developed as a live US fuel price dashboard. The dashboard tracks prices across multiple fuel types and regions, offering granular insights into market trends. For instance, the Conventional area—any area that does not require the sale of reformulated gasoline—allows all types of finished motor gasoline to be sold, which can lead to lower prices compared to reformulated gasoline areas. This distinction is crucial for understanding regional price disparities.

Looking ahead, the recent decline in crude oil prices may provide some continued relief, but the overall trend remains upward compared to last year. Factors such as global supply dynamics, refinery maintenance, and seasonal demand shifts will influence prices in the coming weeks. Drivers should remain prepared for volatility, especially as diesel prices hover near record highs.
