Oil prices remained under pressure following the release on Wednesday of US government data showing a substantial weakening in US demand.

The US data also showed crude stocks up 4.3m barrels last week, above the consensus forecast for a rise of 2.4m barrels, helped by a recovery in imports, up by a substantial 1.85m b/d to average 8.99m b/d last week.
Refineries returning to work after hurricane Ike pushed refinery utilisation up 5.6 percentage points to 72.3 per cent, recovering from the previous week’s record low of just 66.7 per cent.
On Thursday, Nymex October heating oil traded 2.8 cents lower at $2.8148 a gallon. US petrol stocks produced a surprise for traders with an increase of 900,000 barrels, confounding the consensus market forecast for a 1.6m barrel decline.
After falling for nine previous weeks, US crude stocks had shrunk to their lowest levels since 1967, but dealers were uncertain whether the increase in Wednesday’s data marked the start of a new trend.
There was further evidence of weakness in US petrol consumption with gasoline demand averaging 8.87m b/d over the past four weeks, down 4.5 per cent compared with the same period last year.
