LONDON, March 8 (Reuters) - Oil rallied to an eight-week peak above $82 a barrel on Monday, near its highest this year, buoyed by a weaker dollar and signs of an economic recovery in top oil consumer the United States.
Currency movements could set the direction for prices as demand strength may be unclear during the recovery, analysts said.
"We very well could retest the 2010 highs of $83.95," MF Global analyst Edward Meir said.
"However, our belief is that should we get there, a rather substantial correction will set in, sending prices back into the mid-to high $70 range, as some of the long money comes off the table."
U.S. crude <CLc1> was up 59 cents at $82.09 a barrel by 1015 GMT, after touching $82.41, the highest since $83.95 on Jan. 11. Brent crude <LCOc1> was up 65 cents at $80.54 after hitting $80.92, also the highest since Jan. 11.
The dollar index <.DXY> was down 0.20 percent, making oil cheaper for holders of other currencies. The euro gained, helped by easing investor concern about Greece's debts.
French President Nicolas Sarkozy promised Greece on Sunday that euro zone countries would help it overcome its financial problems and vowed a crackdown on speculators who Athens blames for its woes. [

RISK APPETITE
Some analysts do not see oil making a sustained upwards move for the time being.
"We're seeing some recovery in risk appetite. The Greek issues seem to be being sorted out, which is important," said Mike Wittner, analyst at Societe Generale.
"The bottom line is we're nearing the top of the range we've been in since October. We're still looking for rangebound prices. "I'm not quite ready to get too bullish yet."
New York crude rose more than 1 percent on Friday, helped by a government report that showed the United States lost fewer jobs than expected in February. Speculators have also been betting on rising prices.
Money managers extended their net long crude oil futures positions on the New York Mercantile Exchange in the week to March 2, the Commodity Futures Trading Commission said on Friday. [
