LONDON, Nov 21 (Reuters) Oil soared to an all-time high on Wednesday, closing in on the 0 milestone as the U.S. dollar sank to new lows and cold weather in the world's biggest fuel consumer stirred anxiety over winter supplies.
U.S. light crude surged to a record .29 early in the session, but pared gains to stand 29 cents higher at .32 a barrel by 1004 GMT.

Apart from the dollar, the next signal for oil markets will come from U.S. weekly inventory data for release at 1530 GMT.
U.S. weekly distillate stocks -- which include heating oil -- were expected to have declined by 300,000 barrels last week, according to a Reuters poll of analysts ahead of Wednesday's data.
At the same time, crude stocks were predicted to have risen by 600,000 barrels and gasoline stocks by 800,000 barrels.

Energy Secretary Sam Bodman has said producers need to pump more to bring prices down from levels that are close to a record in nominal and inflation-adjusted terms.
But the Organization of the Petroleum Exporting Countries, which meets on Dec. 5 in Abu Dhabi to chart supply policy, has said the market is well-supplied and it is up to consumer countries to curb speculation through regulation.
