Oil prices were mixed in Asia after the Greek government survived a no-confidence vote and as investors awaited the results of a US Federal Reserve meeting.
US crude fell 58 cents to $93.59 a barrel, while Brent crude rose seven cents to $111.02.
The Greek vote eased fears that the country's financial turmoil could worsen and spread across the rest of Europe.
The market was also awaiting the conclusion tonight of a two-day meeting of the US central bank's Federal Open Market Committee (FOMC).
Fed policy-makers were meeting amid signs of weakness in the world's biggest economy - and biggest oil consuming nation - that are clouding prospects for withdrawal from a massive financial stimulus.
