Crude oil ended firm after data showed strong demand in China last month and as OPEC kept output policy intact over the weekend. Cold weather in Europe and the United States also supported crude's rise, but recent sharp gains kept U.S. heating oil's gain for the day limited. Top OPEC producer Saudi Arabia said on Saturday it still favored a $70-$80 oil price range, restating a two-year-old policy as OPEC kept output restraints unchanged despite prices recently reaching $90 a barrel.  Now support for the crude is seen at 3949 and below could see a test of 3923. Resistance is now likely to be seen at 4018, a move above could see prices testing 4061.
