LONDON, Sept 18 (Reuters) - Oil prices fell slightly on Friday as European stocks slipped off their multi-month peaks and a battered U.S. dollar found some respite.
Analysts said a lack of conviction that the global economic downturn was indeed ending had dragged down oil and equities markets on expectations that fuel demand could stay weak.
"It's by and large dollar-related today," said oil trader Rob Montefusco at Sucden Financial in London.
"Once you see the dollar start moving around, we may get back above $72.50, but the market is already in a selling mood."
U.S. crude for October delivery <CLc1> fell 9 cents to $72.38 a barrel by 1341 GMT, after touching as low as $71.27 in earlier trade.
London Brent crude <LCOc1> fell 4 cents to $71.51.
The ICE Futures U.S. dollar index, which tracks the value of the greenback versus a basket of six major currencies, rose slightly on Friday from a near one-year low touched on Thursday, as investors covered short positions after the dollar's sharp slide and softer equities cooled risk appetite.
Recovery hopes in the U.S. and the prospect of low U.S. yields and fiscal deficit concerns have fuelled dollar selling this month, sending the index <.DXY> down 2.4 percent in September, its worst monthly performance since May.
TRACKS EQUITIES
European equities slipped on Friday from an 11-month peak scaled in the previous session, pressured by financial and commodity shares as recent hefty gains prompted investors to book profits. [

Some analysts said oil prices could move higher in coming weeks as some recent positive economic data supported expectations that a global economic revival was under way and energy demand would soon recover.
"Commodity correlations are volatile by nature, and so one needs to be cautious in drawing conclusions from short-term movements," analysts at Barclay's Capital wrote in a their Commodities Research note.
"Momentum is starting to build for a break to the upside as there is mounting evidence of an improving global economy in general."
