What you’re paying at the pump
US national average, $/gallon, mid-2026.
About this data
The AAA national average for regular gasoline was about $3.99/gal by mid-June 2026, easing for nearly four weeks after the spring spike, while diesel ran far higher (~$5.62/gal in mid-May). Diesel matters disproportionately because it moves freight — its price feeds into the cost of nearly everything.

Methodology & sources
Last updated: Aug 5, 2026Methodology
A consolidated US oil & gas data hub. Source-backed values are seeded for all seven charts: the 2026 Brent crude journey through the Strait of Hormuz shock, Henry Hub natural gas annual averages, US crude oil production, the Strategic Petroleum Reserve drawdown, the Baker Hughes rig count, and national pump prices for gasoline and diesel. Every numeric point carries a sources[].ref and a value_basis. Crude and gas prices and production are from the EIA; the rig count is Baker Hughes; the SPR level is EIA weekly stocks with context from DOE and CNN; pump prices are the AAA national average (gasoline) and EIA on-highway price / STEO forecasts (diesel). CAVEAT: the 2026 Henry Hub value ($3.34) and the diesel-related forecasts are EIA projections, labeled as forecasts. The crude chart shows Brent milestone points (not every month); the Jun point also carries the WTI spot ($77.54, Jun 22 2026). The gasoline point (Jun 18 2026) and diesel point (mid-May 2026) carry different dates, each labeled, as the latest cited value per fuel. Re-verified 2026-06-22.
