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: Jul 17, 2026Methodology
Source-backed values are seeded for both charts: current national-average gas vs diesel, and diesel actual vs EIA forecast. Every numeric point carries a sources[].ref and a value_basis. Gasoline is the AAA national average; diesel is the EIA on-highway price and STEO forecasts. CAVEAT: the gasoline point (Jun 18 2026) and the diesel point (mid-May 2026) carry different dates — each is labeled — because they are the latest cited value for each fuel. The Q2 and full-year diesel figures are EIA forecasts. Re-verified 2026-06-22.
