America's supply of crude oil grew by 2.0 million barrels for the week ending July 17, 2026, bringing the total to 411.7 million barrels, according to the U.S. Energy Information Administration (EIA). That total is about 6% below the typical level for this time of year, based on the five-year average from 2021 to 2025. The EIA's summary, dated July 22, 2026, did not point to any single reason for the increase. (EIA)

Refineries — the plants that turn crude oil into fuels like gasoline and diesel — were running at 96.1% of their maximum capacity. That is very high for mid-July and matches what you would expect during peak summer driving season. They processed 17.1 million barrels per day (a barrel is 42 gallons of oil). Gasoline production averaged 9.7 million barrels per day, and diesel and heating oil production rose to 5.3 million barrels per day. (EIA)

Here is where it gets interesting. Even though refineries are producing fuel almost as fast as they can, gasoline stockpiles rose only 0.8 million barrels and stayed about 7% below normal for this time of year. Diesel stockpiles rose 1.4 million barrels but remained 10% below their seasonal average. Think of it like a bakery running its ovens all day but still not catching up on bread orders — the shelves stay thin. (EIA)

Propane tells a very different story. Propane inventories jumped 6.3 million barrels, putting them 34% above the five-year average. Propane is a fuel used for heating, cooking, and making chemicals. While gasoline and diesel are in short supply, propane is piling up. Across all petroleum products combined, total inventories rose 11.6 million barrels. (EIA)

The U.S. imported 5.8 million barrels of crude oil per day, up 117,000 from the prior week. But the four-week average of 5.6 million barrels per day is 11% lower than a year ago. That lines up with a trend: American oil production is replacing foreign shipments. Gasoline and diesel imports were small compared to what U.S. refineries make themselves. (EIA)

On the demand side, total U.S. fuel use over the four weeks ending July 17 averaged 20.4 million barrels per day, down 1% from a year ago. Gasoline demand ticked up 1% to 8.9 million barrels per day. Diesel demand rose 2% to 3.7 million barrels per day. The biggest standout was jet fuel, with demand up 9% year over year. That jump suggests airlines are burning more fuel even though overall fuel use is slightly below last year's levels. (EIA)

The broader picture is a tug of war. Crude oil is piling up and total stocks rose nearly 12 million barrels. But the fuels people actually use — gasoline and diesel — are still below normal even with refineries going all out. The propane surplus is a separate story entirely. The headline number about crude rising does not tell you the full picture. Refineries are working hard, crude is accumulating, and the products that matter most for summer driving are still not fully restocked. None of this is a prediction about where prices are headed. It is a snapshot of where things stand right now.
