New York's main contract, light sweet crude for Mar delivery, fell three cents to USD 89.56 per barrel.
US Department of Energy (DoE) figures released late Thursday showing a surprise rise in crude stockpiles were impacting market sentiment, analysts said.
"There is a hangover from the inventory report, which showed a sizeable crude inventory build, especially in the Gulf Coast region. Commodities are going down slightly but not losing too much ground," said John Kilduff of Again Capital.
DoE data showed crude stockpiles in the world's biggest oil consumer climbing 2.6 million barrels to 335.7 million barrels last week compared with analysts' forecasts of a 900,000-barrel drop.
The contract has been dipped by 3 percent in this week. The Feb contract expired on Thursday, after dropping 2.2 percent to $88.86, the lowest since Jan. 7.
