NEW YORK, Sept 21 (Reuters) - Crude oil prices fell for the fifth time in six days on Tuesday, wilting amid high oil inventories and the Federal Reserve's continued concern about sluggish economic recovery.
Crude futures extended losses right before the close of the oil's open outcry trading session in New York after the U.S. Federal Reserve said it would keep interest rates exceptionally low and that the central bank was prepared to provide additional accommodation if needed to support recovery. [
]The October U.S. crude contract expired on Tuesday, helping keep pressure on the front month and nearby months, industry sources said.
U.S. crude for October <CLV0> delivery fell $1.34, or 1.79 percent, to settle at $73.52 a barrel as it expired and went off the board. Trading ranged from $72.81 to $74.60.
U.S. November crude <CLX0> fell $1.22, or 1.6 percent, to settle at $74.97 a barrel.
ICE Brent for November <LCOc1> fell 90 cents to settle at $78.42.
The premium for November Brent over the equivalent U.S. benchmark West Texas Intermediate contract rose to $3.45, based on settlement prices on Tuesday. The premium shrank below $2 when a leak closed the biggest Canada-to-U.S. crude pipeline but widened when it became apparent flows would resume last week.

"There was pressure on the (U.S.) October contract into its expiry as people realized that we have a glut of supply. That pressed the market down," said Phil Flynn, analyst at PFGBest Research in Chicago.
"The November contract was more affected by the Fed statement today, which didn't inspire any confidence. The economy is still weak and that doesn't bode well for the energy market. The outlook isn't that great."
Oil futures failed to garner any support from a weak dollar, which can lift dollar-denominated crude oil prices because it makes the commodity less expensive in countries using currencies other than the greenback.
The euro rallied more than 1 percent against the dollar on Tuesday, rising to a six-week high after the Federal Reserve statement. [

]API SAYS CRUDE STOCKS ROSE
Late on Tuesday, industry group American Petroleum Institute released its weekly inventory report showing U.S. crude oil stocks rose of 2.2 million barrels last week, against a forecast that stockpiles would have slipped. [
]November crude prices initially extended losses slightly in post-settlement trading after the report.
An analyst survey ahead of the API report had yielded a forecast for crude inventories to be down 1.9 million barrels last week because of lower imports from Canada due to the Enbridge pipeline outage and as tankers navigated around stormy weather. [
]The API report also said gasoline stocks rose, against the expectation they would have fallen, and that distillate stockpiles rose more than expected.
The U.S. Energy Information Administration will release its oil inventory data on Wednesday at 10:30 a.m. EDT (1430 GMT). (Additional reporting by Selam Gebrekidan in New York, Christopher Johnson in London and Alejandro Barbajosa in Singapore; Editing by Lisa Shumaker)
