About this series
Total motor gasoline, including blending components, held in tanks and terminals across PADD 5, the West Coast district. Reported weekly by the U.S. EIA as one of five regional cuts of the national gasoline series. The West Coast is a refining island. Little pipeline capacity connects it to the rest of the country, and California's own gasoline specification is made by few refineries outside the state, so an outage shows up in PADD 5 stocks and prices rather than being papered over by supply from elsewhere.
Today's reading sits in the lower part of the EIA record going back to 1990. West Coast gasoline stocks are running below their typical level.

West Coast gasoline inventory: common questions
- What is PADD 5?
- PADD 5 is the West Coast district of the Petroleum Administration for Defense Districts, the five regions the EIA uses to report US petroleum statistics. It covers Alaska, Arizona, California, Hawaii, Nevada, Oregon, and Washington. The district lines were drawn for World War II fuel allocation and remain the standard regional cut of US oil data.
- What does this page track?
- The total volume of motor gasoline held in tanks and terminals across PADD 5 (West Coast), including blending components not yet mixed into finished fuel. It is the EIA's regional cut of the same weekly series the national gasoline page tracks, and the five districts sum to the US total.
More questions
- Why do West Coast gasoline inventories matter?
- The West Coast is a refining island. Little pipeline capacity connects it to the rest of the country, and California's own gasoline specification is made by few refineries outside the state, so an outage shows up in PADD 5 stocks and prices rather than being papered over by supply from elsewhere.
- How often is this figure updated?
- The EIA publishes the figure every week, typically Wednesday around 10:30 a.m. Eastern for the prior Friday's week. This page reads that same EIA series and shows the latest reading with its as-of date.
