New York's main contract, light sweet crude for November delivery was down two cents to $82.57 a barrel in volatile afternoon Asian trade.
Brent North Sea crude for November was down four cents to $105.69.
"Oil prices remain under pressure and are likely to continue to grind lower over the fourth quarter as the risk of North Atlantic recession weighs," Credit Suisse said in a market commentary.
Crude prices had rallied for a second straight day in New York on Thursday after the European Central Bank announced measures to help cash-strapped banks in the eurozone under pressure from the public debt crises in Greece, Ireland and Portugal.
