seasonalAverage(t) = mean of same EIA week (±1 week) in the five complete years before tWeekly the four-week average of U.S. product supplied of finished motor gasoline (EIA series WGFUPUS2), plotted against the five-year seasonal average only for the same calendar week. The reference uses the same EIA week number (plus or minus one week) in the five full calendar years before each observation. The current year never enters its own baseline. Each reference year contributes the mean of its tolerated observations. The average line starts once a five-year window exists.
As of 31 July 2026, the latest readings are Gasoline demand (4-week avg) at 8965.75 Thousand Barrels per Day and Five-year average at 9071.82 Thousand Barrels per Day. The Gasoline demand (4-week avg) line is up 0.6% over the past year and above its long-run median of 8809.75 Thousand Barrels per Day.
Product supplied is EIA's demand proxy. Barrels removed from the system. Not a direct meter reading, and the four-week average smooths the weekly noise. A reading above the seasonal band means consumers are burning more gasoline than the time of year warrants, pulling down stocks and supporting crack spreads. A reading below the band means weak driving demand. Softness that lets inventories build and caps refinery margins.
Energy series move with the calendar year. A raw level cannot say if the market is tight or slack. This page ranks each week against the same week in the five full years before it. A July reading is judged against prior Julys, not against the full year. The baseline uses only earlier years. The current year never enters its own baseline. The rule allows one week of tolerance when holidays shift the report week.
For each date, the reference is the same EIA week number (plus or minus one week) in the five full calendar years before it. Each reference year adds one value (the mean of its tolerated observations). The five-year average uses those yearly values. This page plots the average only. The average line starts once a five-year window exists and rolls forward.
The five-year average moves as history rolls forward. Source revisions can move history. Gasoline demand is one input to the market balance. Prices also move on the weekly surprise versus expectations, not on the level alone. Treat the chart as context for supply and demand conditions, not investment advice.
Memorial Day to Labor Day is the demand peak, and the four-week-average convention is the market's standard smoothing. The EIA weekly report itself leads with the four-week average product supplied. The seasonal band here shows whether the driving season is running ahead of or behind the historical pattern, which is the first question for gasoline crack positioning.
This page uses a same-week rule over five full prior years. It allows one week of tolerance. The current year is excluded. It plots the seasonal average only. Compare the reading to the average line, not to a min or max range.
As of 31 July 2026, the latest readings are Gasoline demand (4-week avg) at 8965.75 Thousand Barrels per Day and Five-year average at 9071.82 Thousand Barrels per Day. The Gasoline demand (4-week avg) line is up 0.6% over the past year and above its long-run median of 8809.75 Thousand Barrels per Day.
This benchmark is built on weekly data. The page is refreshed when the source publishes new observations; the freshness block below the chart shows the exact data-through date and when PIER20 last fetched the file.
The chart is built from Gasoline demand (4-week avg) and Five-year average, sourced from the U.S. Energy Information Administration (EIA).
The percentile cell ranks the latest reading against the full sample. The 100th percentile is the highest on record. The 0th is the lowest. This page charts the five-year seasonal average only. Read extremes from the full history and the percentile cell.
This page is the flow (demand), not the stock. Inventories answer 'how much gasoline is in tanks'; product supplied answers 'how much is being consumed'. The two move in offsetting rhythm. Strong demand draws stocks. And the demand-vs-stock pair is the standard read on whether the market is balanced.
A baseline needs five full prior years of observations. The current year never enters its own baseline. The first five years of a series have no complete reference window. Earlier readings plot without a seasonal reference.
One tested idea, through the evidence stack. No migration of any kind.
