Regular gasoline in Colorado averages $4.05 per gallon as of the EIA week of 2026-08-10 — $0.04 above the national average of $4.01. Colorado sits in the isolated Rocky Mountain refining region — a handful of local refineries (notably Suncor in Commerce City) plus pipelines from the Gulf Coast serve the whole area, so a single outage moves prices sharply. State fuel taxes are moderate, but mountain-market logistics and periodic refinery problems keep Denver-area prices volatile.
