Oil prices fell following improvements in the dollar and a higher-than-expected increase in US crude inventories last week.

US crude for December fell 40¢ to stand at $82.15 a barrel at 06.20 GMT while London Brent dipped 40¢ to $83.26, reports Reuters.

The dollar improved on expectations that the Federal Reserve will buy assets aggressively to infuse more money into the system.

US crude inventories increased by 6.4 million barrels in the week ending 22 October, according to the American Petroleum Institute.

Distillates grew by 818,000 barrels, while petrol fell by 1.8 million barrels.
