NEW YORK, Sept 15 (Reuters) - U.S. crude oil futures rose Tuesday as reports of higher U.S. retail sales and producer prices lifted oil despite the usually bearish factor of a stronger dollar. "Looks like retail sales and PPI data supported. Crude is ignoring the dollar for now. Crude held trend-line support yesterday near $68 and is back in bounce mode," said Tom Bentz, analyst at BNP Paribas Commodity Futures Inc. Sales at U.S. retailers rose at their fastest pace in three-and-a-half years in August, according to data released Tuesday by the Commerce Department. [ID:nN14478930] U.S. producer prices rose more than twice as much as expected in August on the biggest surge in gasoline prices in more than 10 years and prices declined less than expected compared with a year ago, a government report showed on Tuesday. [ID:nN15543702] The dollar rose broadly against a basket of major currencies for a second day on Tuesday. [USD/] U.S. equities turned positive after a tepid opening.
