Regular gasoline in Washington averages $5.06 per gallon as of the EIA week of 2026-08-10 — $1.05 above the national average of $4.01. Washington combines one of the nation's highest state gas taxes with a carbon cap-and-invest program that adds a per-gallon compliance cost, and the isolated West Coast fuel market means local refinery hiccups can't be quickly backfilled from other regions.
