West Coast distillate inventory ·EIA week ending September 4, 2026
West Coast distillate storage holds 10.1 M bbl as of September 4, 2026, up 1.7% week over week.
The Desk's read
West Coast diesel and heating fuel stocks are running unusually lean, sitting at 10.1 MM bbl as of 2026-09-04, which lands in the 5th percentile of the 37-year record. This is the metal that actually clears delivery, and there is not much of it on the ground. The 30-day change of -2.6% is a moderate draw; the trailing eight-report pace sits mid-range for the record, so the thinness reflects a shallow pile more than a violent drain. We watch next Wednesday's EIA weekly report for the reading after 2026-09-04.

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.
Since 2015, today's reading ranks in the 1st percentile. West Coast distillate stocks are lean by modern standards. It is 1.7M bbl below its same-week five-year average. Across the full EIA record back to 1990 it ranks in the 5th percentile; storage capacity, pipelines, and production have shifted enough since then that the modern cohort is the better yardstick for today's operating conditions.

- What does this page track?
