The Desk's read
West Coast diesel and heating fuel sits thin, at 10.6 MM bbl as of 2026-08-21, the 13th percentile of the 37-year record. The pile is lower than most of its history, and the recent draw has not been dramatic: down 2.0% over 30 days, with the trailing four-report pace at the 21st percentile of all such stretches, toward the drain side but well within range. We track the next EIA weekly report next Wednesday; watch whether that pace holds against an already lean base.

About this series
Distillate fuel oil, the category covering diesel and heating oil, 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 distillate series. West Coast distillate supplies ports, agriculture, and freight from an isolated refining system with no pipeline link to the rest of the country. California's renewable-diesel shift is also reshaping the region's diesel pool, one reason this district's trend can diverge from the national one.
Today's reading sits in the lower part of the EIA record going back to 1990. West Coast distillate stocks are running below their typical level.

West Coast distillate 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 distillate fuel oil, covering diesel and heating oil, held in tanks and terminals across PADD 5 (West Coast). It is the EIA's regional cut of the same weekly series the national distillate page tracks, and the five districts sum to the US total.
More questions
- Why do West Coast distillate inventories matter?
- West Coast distillate supplies ports, agriculture, and freight from an isolated refining system with no pipeline link to the rest of the country. California's renewable-diesel shift is also reshaping the region's diesel pool, one reason this district's trend can diverge from the national one.
- 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.
