NEW YORK, Nov 30 (Reuters) - Oil fell on Tuesday as concerns that Europe's debt crisis will widen battered the euro and added to worries about Chinese oil demand.
Front-month December U.S. heating oil <HOZ0> and gasoline <RBZ0> futures slumped as those contracts expired and went off the board, also weighing on crude. On Monday, cold weather boosted distillates and tight New York Harbor supplies lifted gasoline, helping boost crude prices post a 2 percent gain.
U.S. crude oil for January delivery <CLc1> fell $1.62, or 1.89 percent, to settle at $84.11 a barrel, then extended its losses to $83.55 in post-settlement trade.
But U.S. oil finished November up 3.29 percent from October, a third consecutive monthly gain and the biggest since September, when front-month crude jumped 11.2 percent.
Total U.S. crude trading volume on Tuesday was above 470,000 lots with about 1-1/2 hour left for trading, 24 percent below the 30-day average.
In London, ICE January Brent crude <LCOc1> fell $1.42 to settle at $85.92 a barrel.
"Crude sold off mainly on the concerns about the euro zone economy and the Shanghai index slipping didn't help," said Chris Dillman, analyst at Tradition Energy in Stamford, Connecticut.
The dollar index <.DXY> against a basket of currencies reached a more than two-month peak as the euro <EUR=> tumbled on continuing fears that Ireland's bailout might not help keep Europe's debt problems contained. [
]Converting prices to euros, Brent reached its highest level for almost seven months on Tuesday, climbing above 67 euros per barrel. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Graphic of Brent in euros and the dollar index: http://link.reuters.com/bef77q Graphic of the components of the CRB commodity index: http://graphics.thomsonreuters.com/F/08/CRB291110.gif ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^>
Robert Montefusco at Sucden Financial in London said the weakness of the euro was putting increased pressure on oil.
"That puts pressure on the fundamentals," Montefusco said. "Fear of contagion with not only Portugal and Spain, but now with France and Belgium in focus as well."
Oil and dollar-denominated commodities often move inversely to the dollar. A stronger dollar typically pressures oil prices as it boosts the value of greenbacks paid to producers while making it more expensive for consumers with other currencies.
China's key Shanghai stock index <

Factories in Japan and South Korea, Asia's second- and fourth-largest oil users, cut output in October, in a region oil producers look to for demand growth. [
]U.S. economic data was mixed, with reports showing consumer confidence at a five-month high in November and Midwest business activity growing faster than expected helping oil bounce earlier on Tuesday, even as a report on falling home prices disappointed. [
]U.S. OIL INVENTORIES
U.S. crude oil inventories were expected to have fallen 900,000 barrels last week as imports dipped, a Reuters analyst survey on Tuesday said. Gasoline stocks were expected to be up, with distillate stockpiles down. [
