U.S. crude stockpiles rose slightly more than expected in the week ended March 27, according to data released Wednesday by the U.S. Energy Information Administration.

Crude-oil stockpiles gained 4.8 million barrels to 471.4 million barrels, the EIA said. Analysts surveyed by The Wall Street Journal had predicted a 4.6 million-barrel increase on the week. Stockpiles remain at the highest in about 80 years, according to the EIA.

Oil stored at Cushing, Okla., the delivery point for U.S. benchmark oil futures, rose 2.6 million barrels to 58.9 million barrels, a new all-time high based on weekly data going back to April 2004.

Gasoline stockpiles fell by 4.3 million barrels to 229.1 million barrels, the EIA said in its weekly report, the lowest level this year. Analysts had predicted stockpiles would fall by an average of 900,000 barrels.

Distillate stocks, which include heating oil and diesel fuel, rose 1.3 million barrels to 127.2 million barrels, the EIA said. Analysts had expected a 300,000-barrel weekly decrease.

Refining capacity utilization rose 0.4 percentage point to 89.4%. Analysts had predicted the operating rate would rise half a point from the previous week.

Figures are in millions of barrels, rounded, except for refining use, which is reported in percentage points. Forecasts are the average of expectations in a Wall Street Journal survey of analysts earlier in the week.
