US Regular Gas Price (Weekly National Average)

Primary source

All values come directly from EIA via FRED (GASREGW). We do not modify, smooth, or interpolate published values.

Weekly national average retail price of regular-grade gasoline in the US. Published every Monday by the Energy Information Administration based on a survey of ~900 gas stations. Direct consumer cost signal tracked by Fed and fiscal authorities.

Update schedule

Weekly — we refresh daily; upstream source publishes once per week (check Next Update below).

We gate dateModified updates to actual value changes (threshold: 0.01% absolute or 0.5% relative) to prevent freshness spoofing. If the upstream value hasn't moved, we don't claim we updated the page.
