LONDON, April 27 (Reuters) - Oil slipped below $84 on Tuesday, pulled lower by expectations of a rise in U.S. stockpiles and nagging concerns Greece's economic trauma could have knock-on effects on the wider economy and demand for fuel.
U.S. crude for June delivery <CLc1> fell $1.01 to $83.19 a barrel by 1305 GMT, while ICE June Brent crude <LCOc1> dipped by 81 cents to $86.02.
"The market is a little worried about the Greece situation and probable builds in inventories again in the U.S. statistics," said Tony Nunan, a risk manager with Mitsubishi Corp.
Inventories of crude oil in the United States, the world's top energy consumer, probably rose for the second consecutive week, a Reuters' survey of analysts showed ahead of two sets of oil data to be released later on Tuesday and Wednesday. [
]Industry group American Petroleum Institute will release its report for the week to April 23 at 2030 GMT on Tuesday. Official Energy Information Administration data will follow at 1430 GMT on Wednesday.
Analysts in the survey expected a 400,000 barrel increase in U.S. crude oil stocks. Oil product inventories, such as gasoline, were also forecast to rise. [
]The oil futures market structure, rather than outright prices, has reflected high levels of inventories especially at at Cushing in Oklahoma, the United States, the delivery point of U.S. crude.
The swollen inventories have made the prompt U.S. crude futures cheaper than longer dated contracts, a structure called contango, which has steepened over the past month. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

The euro slipped and European shares dipped in response to renewed worries about Greece's debt after Germany demanded painful new austerity measures from Athens in return for financial aid. [
][ ]But oil markets are still factoring in economic recovery and rising demand.
Oil has risen by about 65 percent from a year earlier, led higher by growth in demand from emerging markets such as China and brightening outlooks for U.S. economy. In late April last year, U.S. crude futures were trading around $50-$51.
British oil major BP plc <BP.L>, the first international oil major to report first quarter earnings, benefited from the rise in oil prices and posted a 135 percent increase in profit from a year earlier [

Traders will look for further clues to economic recovery from the U.S. April consumer confidence data on Tuesday, as well as the outcome of the Federal Reserve's two-day, policy-setting meeting, also starting Tuesday.
