* U.S. crude inventories gain despite increasing demand
* Oil likely to rise to $80-$90 range, Barclays says

SINGAPORE, March 4 (Reuters) - Oil slid towards $80 on Thursday as the dollar strengthened, pushing the fuel off seven-week highs struck a day earlier as U.S. demand edged up in a recovering economy.
The dollar gained close to 0.3 percent against a basket of currencies, sending crude down 50 cents to $80.37 a barrel by 0747 GMT. The front-month contract touched $81.23 on Wednesday, its highest intraday price since Jan. 12. London ICE Brent for April fell 40 cents to $78.85.
"The oil market will trade in a range of $75 to $85 at least for the next two months, and it will possibly go above $85 by the middle of this year, depending on economic recovery," said Ken Hasegawa, a commodity derivatives manager at brokerage Newedge in Japan.
Total U.S. oil demand grew 0.3 percent in the past four weeks from a year earlier, U.S. government data showed on Wednesday, raising expectations for an end to a 1-1/2-year period of sustained consumption decreases.
Greece's budget-balancing pledges on Wednesday helped restore some appetite for risk, boosting the euro against the dollar. On Thursday, the spotlight shines again on the euro zone when it reports revised gross domestic product for the fourth quarter.
China Investment Corp, the country's sovereign wealth fund, believes commodity prices are outpacing the global economic recovery, fuelled by loose monetary policies, a top official said on Thursday.
"Personally, I think the prices are a bit too high, relative to the strength of real economic recovery," Jesse Wang, CIC executive vice president and chief risk officer, said on the sidelines of a conference in Beijing. [
]DEMAND VS INVENTORIES
Prices have ranged $69 to $84 a barrel over the past few months amid uncertainty about the pace of economic recovery. But a decline in global crude inventories and the surplus held in floating storage has set the stage for an increase towards the $80-$90 range, according to Barclays Capital.
The latest data from the Joint Oil Data Initiative (JODI) implied that Asian demand has been growing by more than 2 million barrels per day from a year earlier, according to Barclays.
"If Asian demand can grow at such rapid rates when prices are in the $70 to $80 range, then prices cannot stay in that range for much longer," Barclays analysts headed by Paul Horsnell said.
Interest rate decisions from the Bank of England and the European Central Bank are also expected on Thursday, followed by U.S. durable goods and factory order statistics for January. And on Friday, attention will turn to U.S. non-farm payrolls.
Some doubts remained about the pace of economic recovery. Newedge's Hasegawa said it is still "slow", adding that any oil price gains could accelerate with "short-covering" when prices reach $81.50 and $82.
U.S. crude inventories last week rose a larger-than-expected 4.1 million barrels, the Energy Information Administration (EIA) said on Wednesday.
The dollar had fallen against the euro on Wednesday as concerns eased about deficits in European countries. A weaker dollar tends to support oil prices, making dollar-denominated commodities cheaper for other currency holders.
