NEW YORK, April 15 (Reuters) - U.S. oil prices edged lower in choppy trading on Thursday as a stronger dollar and mixed economic data pulled crude back from earlier gains that followed robust economic data from China.
"We are looking at the data from China and this is very supportive for the market," said Christophe Barret, oil analyst at Credit Agricole Corporate and Investment Bank. "But I think the growth was anticipated and was already in the prices."
In London, Brent crude futures remained up sharply ahead of the expiration on Thursday of the front-month May contract, even as the approaching expiration of May crude oil options helped keep U.S. oil prices curbed, sources said.
Front-month U.S. crude <CLc1> for May delivery was down 26 cents at $85.58 a barrel at 1:17 p.m. EDT (1717 GMT), after ending 2 percent higher the previous day. ICE Brent crude for May rose $1.06 to $87.21 a barrel on the day of its expiration.
Brent is trading at a premium to U.S. benchmark West Texas Intermediate crude a fourth consecutive day due partly to the approaching Brent contract expiration and traders also cited rising stockpiles at the Cushing, Oklahoma, delivery point for WTI, among other factors. [

]SURPRISE DROP
Oil prices rose more than 2 percent on Wednesday, ending a five-day losing streak after U.S. government data showed a surprise 2.2 million-barrel drop in U.S. crude stocks.
But the report also showed a larger-than-expected 1.1 million barrel rise in distillate stocks including diesel, raising questions about the pace of the U.S. exit from recession. [
