LONDON, Feb 10 (Reuters) - Oil fell towards $73 a barrel on Wednesday, dented by worries about weak demand in the world's top two consumers after figures showed a large build in U.S. crude inventories and a fall in China's imports.
U.S. crude futures <CLc1> fell 37 cents to $73.38 a barrel by 0925 GMT. On Tuesday, crude futures rose more than 2 percent to settle at $73.75. Crude oil is still on track a 2.1 percent rise this week.
ICE Brent crude futures <LCOc1> were down 50 cents at $71.63.
Crude stocks in the United States, the world's largest oil consumer, increased by 7.2 million barrels to 337.6 million barrels in the week to Feb. 5, industry group American Petroleum Institute (API) said late on Tuesday.
The increase in crude inventories exceeded analysts' expectations for a 1.5 million barrel rise. [
]The release of official data from the U.S. Energy Information Administration (EIA) has been delayed to Friday from Wednesday, when it is normally released, because government offices were closed due to a snow storm.
"In absence of the government data, the market should continue trading under the spell of yesterday's API data. The further fall of the refinery utilisation is worrisome," Eugen Weinberg, commodities analyst with Commerzbank said.
The API data showed the refinery utilisation rate fell to 77 percent from 78 percent in the previous week and from 81.9 percent in the same week a year ago.
"It is the lowest level since Feb 1987, without hurricanes, pointing to still very fragile oil demand in the United States," Weinberg said.
Crude prices are down nearly 8 percent this year to stand at about half their July 2008 high of more than $147 a barrel.
Further pressure came from China and a stronger dollar.
Chinese crude imports slid in January, down to 4.03 million barrels per day from their December peak of 5 million bpd, although they were still up 33 percent on the year.
Net fuel exports from China were about 160,000 tonnes, customs figures showed. [
]Olivier Jakob with Petromatrix said the crude import volume was the lowest level since May last year.
"With product exports more than double the levels of a year ago, China has turned for the second month in a row into a net exporter of petroleum products," he said in a research note.
The euro slipped on Wednesday, relinquishing some gains made the previous day as the market braced for a European Union summit, speculating that member countries may help Greece tackle its fiscal problems. [
]Comments from a senior German coalition source that European governments had agreed in principle to support heavily indebted Greece had helped the euro to rally on Tuesday. [
