Crude falls as dollar advances

Crude oil prices weakened Tuesday as traders reacted to the strengthening U.S. currency, making dollar-priced crude more expensive for foreign buyers dampening demand, analysts said.

New York's main contract, light sweet crude for delivery in October, fell as much as 2.75 dollars to 112.36 dollars a barrel in electronic deals. At 11.15am it stood 2.07 lower at $113.04/barrel.
