By early afternoon in Europe, benchmark crude for October delivery was down 38 cents at $94.92 a barrel in electronic trading on the New York Mercantile Exchange. The contract fell $1.17 to close at $95.30 per barrel on the Nymex on Tuesday.
In London, Brent crude was down 67 cents at $113.61 on the ICE Futures exchange.
Energy market sentiment was lifted in early trading by report showing U.S. new car and truck sales rose 20 percent in August to 1.3 million vehicles — a sign that gasoline consumption could be on the upswing in the world's No. 1 economy.

The American Petroleum Institute will release its report on oil stocks later Wednesday, while the report from the Energy Department's Energy Information Administration — the market benchmark — will be out on Thursday, a day later than usual because of Monday's Labor Day holiday.
The reductions in stock are likely due to lower imports and the temporary shutdown of oil production facilities in the Gulf of Mexico region because of Hurricane Isaac, Platts said.
