SINGAPORE, Nov 4 (Reuters) - Oil rose for a fourth straight day on Thursday, trading near six-month highs, as the dollar weakened after the U.S. Federal Reserve unveiled a plan to buy debt and pump more money into the economy.
U.S. crude for December <CLc1> rose 61 cents to $85.30 a barrel at 0435 GMT, after touching $85.36 on Wednesday, the highest intraday price since May 4. ICE Brent for December <LCOc1> gained 56 cents to $86.94.
The U.S. central bank on Wednesday said it would buy around $75 billion in Treasury bonds per month through mid-2011, totaling around $600 billion. The dollar weakened about 0.2 percent on Thursday against a basket of currencies. <.DXY>
Wide anticipation of the Fed stimulus measures -- meant to avert deflation and create jobs by easing long-term borrowing costs -- boosted the price of oil from mostly within a range of $72-$80 in September to $80 and above in October and November.
"After the Fed meeting, a trend of weakness in the dollar will continue, so oil can still move to the upside," said Ken Hasegawa, a commodity derivatives manager at Japan's Newedge brokerage.
The Fed's plans are in line with consensus expectations, but are less aggressive than some polled by Reuters had anticipated. Estimates for overall Fed asset purchases ranged from $250 billion to $2 trillion.
Following the Fed's announcement, commodities investors may return to closer scrutiny of the fundamentals of oil supply and demand and broad economic indicators, analysts said.
"Some indices of the economy are showing good data recently, and in addition the inventory of oil has been reduced. That is also a good factor to buy," Hasegawa said.
FUEL SURPLUS SHRINKS
U.S. stocks of gasoline fell by 2.7 million barrels, while distillate fuels, including heating oil and diesel, slid by 3.6 million barrels as the country's refineries cut utilisation rates to the lowest since March, the Energy Information Administration reported on Wednesday. [
]Although fuel stocks fell, U.S. crude stockpiles rose by 2 million barrels last week, EIA figures showed, leaving a major crude surplus compared to the same period of 2009.

The U.S. services sector grew more quickly than expected in October and factory orders posted their largest gain in eight months. Also, a report showed U.S. private employers added more jobs than expected in October. [
]More evidence about the state of the U.S. economy, which would affect future demand, will arrive on Thursday, with weekly jobless claims data, and Friday, with monthly payrolls data and the unemployment rate from the Labor Department.
Technical analysis of oil prices, based on trends and charts, shows a bullish target of $87.04 for U.S. crude remains unchanged, as per its wave pattern and a channel technique.
"Oil finally went above $85, and now it may go up to $87 or $88 from a technical point of view as short-covering may be triggered," Hasegawa said.
"From a fundamental perspective, a price of $90 would be too high. There is not so much buying interest at that level and a lot of selling orders would come in."
Asian stocks rose to their highest levels since June 2008 and commodity prices rallied on Thursday after the Fed's new bond-buying programme kept the hunt on for growth and higher yields. [
]Wednesday's underwhelming financial market response to the Fed's move is unlikely to dismay central bank officials who carefully telegraphed the move to avoid market disruptions. [
]Analysts said markets had widely priced in the Fed move prior to the announcement, which was for a slightly higher amount than expected with purchases spread out over a longer period than anticipated. (Editing by Manash Goswami)
