LONDON, April 28 (Reuters) - Oil rose towards $83 a barrel in volatile trade on Wednesday, as a drop in gasoline stocks in the United States and moves towards a larger plan to help severely indebted Greece overshadowed mounting crude stocks.
Stocks of crude oil in the United States rose by 1.9 million barrels last week, the U.S. Energy Information Administration (EIA) said, topping analysts' expectations. [
]"We've seen crude builds in 12 out of the last 13 weeks, and crude is still over $80 (a barrel)," said Jason Schenker, president of Prestige Economics in Austin, Texas.
"Fundamentally, it's a bearish (EIA) report, but inventories aren't the main factor driving markets right now."
Distillate stocks also rose, posting a gain of 2.9 million barrels, though gasoline stocks declined by 1.2 million barrels.
U.S. crude for June delivery <CLc1> fell to a low of $81.29, before paring losses to trade up 39 cents at $82.83 by 1509 GMT. Prices are down by more than $2 so far this week.
London Brent for June delivery <LCOc1> was down 20 cents at $85.58 a barrel.
A day after ratings agency Standard & Poor's cut Athens' debt status to junk, news that a larger joint eurozone and International Monetary Fund aid package for Greece was imminent helped to underpin investments into risky assets such as energy.
A eurozone/IMF aid package for Greece will be worth 100-120 billion euros over three years, according to IMF Managing Director Dominique Strauss-Kahn, opposition members of Germany's parliament said after meeting him. [
]U.S. equities rose on Wednesday as details emerged of the plan. European shares had earlier slumped to a seven-week low while the euro hit a one year-low against the dollar before bouncing to trade higher on the day.
Oil and other dollar-denominated commodities tend to move in the opposite direction to the greenback, as a weaker dollar makes them cheaper for other currency holders and vice versa.
"The negative side (is) focusing on yesterday's break of the 50-day moving average, ongoing worries about Greek debt, and an increased likelihood of position limits and financial regulation," said MF Global analyst Tom Pawlicki.
"The positive side will cling to the belief that investment can be maintained and save the market from falling."
In the past two days, oil prices have twice fallen below the 50-day moving average, a key technical indicator that often proves a battleground for optimists and pessimists in the market. The 50-day moving average is currently at $82.10. (Additional reporting by Gene Ramos in New York and Alejandro Barbajosa in Singapore; editing by Keiron Henderson)
