* China's crude imports surge in March, data show
(Updates prices, detail)

LONDON, April 12 (Reuters) - Oil prices slipped below $85 a barrel on Monday, consolidating despite a drop in the dollar and bullish data showing a big jump in Chinese crude imports.
Technical chart analysts said the oil market was running out of upward momentum after a sharp rise in prices at the end of March and in early April. The pull-back came despite factors that analysts said were supportive for the market.
Euro zone finance ministers approved a giant 30 billion euro ($40 billion) emergency aid mechanism for debt-stricken Greece on Sunday but stressed Athens had not requested the plan be activated yet. [
]The news drove the euro to its highest levels in nearly a month in Asian trade, while the dollar index <.DXY> fell 0.6 percent against a basket of currencies on Monday.
A weak dollar often supports oil prices, making commodities denominated in dollars cheaper for other currency holders.
U.S. crude for May delivery <CLc1> was down 36 cents to $84.56 a barrel by 1323 GMT, wiping out an earlier 79 cent gain.
"The weaker dollar and strongly bullish Chinese data should be very positive for oil," said Daniel Briesemann, commodities analyst at Commerzbank. "Of course fundamentally, these high oil prices cannot be justified, but based on sentiment, the market still has room to go up, we think."
London Brent crude <LCOc1> rose 7 cents to $84.90, moving to a premium above U.S. crude, also known as WTI, for the first time in months with traders saying the North Sea grade was benefiting more than its U.S. counterpart from the Chinese data.
TARGET $90?
"International demand ... is having a more positive impact on Brent than WTI," said Christopher Bellew, broker at Bache Commodities. "U.S. crude oil stocks are high and WTI has its limitations as an (international) marker price because it is based on a landlocked crude, well away from the coast."
The last time Brent futures traded consistently above U.S. crude was in December.
China's strong demand for oil and copper showed no let-up in March, with imports rising rapidly despite higher prices as factories returned to work in earnest after the long Lunar New Year holidays. [
]Chinese crude imports jumped 13.8 percent from the previous month and reached 4.95 million barrels a day, preliminary data released by the General Administration of Customs showed.
In a sign of upbeat sentiment, open interest positions were heavier at the NYMEX May $90 call option and the $80 and $75 put options, according to Reuters data on Friday. [
]Money managers also extended net crude oil long positions on the New York Mercantile Exchange to a record 186,732 in the week to April 6, up from 169,478 in the previous week, the Commodity Futures Trading Commission said on Friday. [
]But crude oil's positive momentum has been showing signs of running out of steam, technical analysts said, making a test of support more likely for now than a fresh move to the upside.
"The positive momentum on WTI is starting to peak," said Olivier Jakob, analyst at Petromatrix. "The challenge this week for the bulls will clearly be to maintain support (at) $85." (Additional reporting by Fayen Wong in Perth; editing by Sue Thomas)
