New York's main contract, light sweet crude for delivery in December, shed 46 cents to $82.09.
Brent North Sea crude for December delivery dipped 34 cents to $83.26 .
Prices were retreating following a crude rally Wednesday, said Serene Lim, oil and gas analyst from ANZ bank in Singapore.
"I think it could likely be profit-taking today," she said of the price fall.
Crude markets had jumped on Wednesday on a weaker dollar and a lower-than-expected rise in US crude inventories.
Prices were also constrained by the $83 price ceiling, which Lim described as a "very strong resistance level".
Traders were eyeing the release of Asian economic titan China's third-quarter gross domestic product (GDP) and industrial production figures for market leads, Lim added.
China said Thursday its economy posted robust, albeit slightly slower, growth in the third quarter after a crackdown on soaring property prices and bank lending had less impact than expected.
Consumer prices rose at their fastest pace in nearly two years in September, official data showed -- an apparent explanation for Beijing's decision this week to hike interest rates for the first time since 2007.
