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.
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.
