How it was measured: FactVote uses EIA’s Gulf Coast series, the smallest current EIA retail region that includes New Mexico. Changes are calculated from the published August 31, 2026 (prior week), and September 8, 2025 (52 weeks earlier), observations.
Keep in mind- EIA does not publish a current New Mexico statewide weekly gasoline-price series. This Gulf Coast regional estimate should not be read as New Mexico’s statewide average.
- The regional average combines Alabama, Arkansas, Louisiana, Mississippi, New Mexico, and Texas, and does not represent the price at every station or in every New Mexico community.
- Prices are nominal and not adjusted for inflation or seasonal patterns. Weekly estimates can be revised and can differ from monthly averages.
- Price changes alone do not establish the effect of any bill, official, or government action.
