NEW YORK, Nov 3 (Reuters) - Oil prices firmed to near $85 a barrel, after touching a six-month high earlier Wednesday, as weekly data showed U.S. fuel stocks fell last week and traders bet that the U.S. Federal Reserve would announce economic stimulus measures that could boost commodities prices.
U.S. stocks of gasoline and distillate fuels fell more sharply than expected last week, while crude stocks rose as expected, as the country's refineries cut utilization rates to the lowest since March, weekly data from the U.S. Energy Information Administration showed. [

U.S. crude for December delivery <CLc1> firmed 81 cents to $84.71 a barrel by 1:43 p.m. EDT, after rising to a six-month high of $85.36 earlier Wednesday. ICE December Brent <LCOZ0> was at $86.36, up 95 cents.
Anticipation of Fed monetary easing actions have helped to weaken the dollar by around 9 percent since late August. After gaining earlier in trade, the U.S. currency fell against a basket of foreign currencies ahead of the Fed statement <.DXY>.
A weak dollar can make commodities more attractive to investors. Fed easing may cheapen borrowing costs, potentially expanding the pool of dollars flowing into commodities markets.
The expected Fed measures have already been priced into oil markets, paving the way for potential sell-offs should the plans to purchase U.S. government debt appear less aggressive than consensus estimates of $80 billion to $100 billion per month in a Reuters poll of economists. Anything less could firm the dollar and pressure oil prices, analysts say.
"A lot of the Fed announcement has already been factored in. (Fed officials) are probably not in favor of decimating the dollar any further. If the dollar rebounds that would suggest that the oil market would retreat a bit," said Gene McGillian of Tradition Energy in Connecticut.
Estimates for how long the Fed will continue easing with debt purchases and how much it will spend overall varied from $250 billion to $2 trillion in a Reuters poll.
"From a risk point of view, the (Fed) risks are rather skewered to disappointment, and could limit the upside in oil prices today," Commerzbank oil analyst Carsten Fritsch said.
U.S. FUEL INVENTORIES FALL, ECONOMIC DATA IMPROVE
U.S. crude stockpiles rose by 2 million barrels last week, roughly in line with analyst expectations. But distillate stocks shrank by 3.6 million barrels and gasoline stocks fell by 2.7 million barrels, whittling down overall U.S. fuel stocks by more than expected last week, as U.S. refinery utilization fell to 81.8 percent, the lowest rate since March.
The U.S. services sector grew more quickly than expected in October and factory orders posted their largest gain in eight months. Also, a private report showed U.S. private employers added more jobs than expected in October.
Some analysts also linked oil's rise on Wednesday to results of the U.S. mid-term elections on Tuesday, which put Republicans -- often considered more friendly toward the oil industry -- back in control of the House of Representatives and saw them gain ground in the Senate.
"Republicans are perceived as more oil friendly so the election may be helping support (oil)," said Richard Ilczyszyn senior market strategist at Lind-Waldock in Chicago.
