The national average price for a gallon of regular unleaded gasoline stands at $4.151 this week. That figure means most American drivers are spending roughly $60 to $80 to fill a standard-sized tank, depending on the vehicle. While the average remains above the $4 threshold, prices vary widely depending on where a driver lives, making the national number more of a benchmark than a precise local guide.
Prices have climbed seven cents compared to last week and nearly eleven cents compared to one month ago. That steady upward movement suggests supply pressures or increased demand are pushing costs higher rather than a single sudden event. Seasonal factors play a role, as warmer months typically bring more driving and a switch to summer-blend fuels, which cost more to produce. Crude oil prices and refinery output remain the primary forces behind week-to-week changes at the pump.
The gap between the most and least expensive states is striking this week. California drivers pay $5.860 per gallon, followed by Washington at $5.515 and Hawaii at $5.389, all well above the national average due to state taxes, environmental regulations, and regional supply constraints. On the other end of the scale, Indiana averages $3.431, Texas sits at $3.667, and Oklahoma comes in at $3.701, reflecting lower taxes and easier access to refining infrastructure.
Next week, drivers should watch for any shifts in crude oil markets, which remain the single biggest variable in pump prices. If the upward trend continues at its current pace, several more states could push above $4.50. A slowdown in demand or an increase in domestic supply could ease prices, but for now the trajectory points modestly upward heading into the coming days.
