Oil prices pushed higher for a second straight day Wednesday on continued weakening of the U.S. dollar and as investors awaited the outcome of an OPEC meeting that is expected to result in no change in production levels.
Benchmark crude for October delivery climbed $1.15 to $72.25 a barrel on the New York Mercantile Exchange.
On Tuesday, the contract jumped $3.08 to settle at $71.10 as the dollar fell to a low for the year against the euro.

Prices are about twice their levels from December, when OPEC announced its record 4.2 million barrel per day cut from September 2008 levels. The price rally has been welcome news for cash-hungry member governments, but also a temptation to sell more oil.
Kuwait's oil minister, Sheik Ahmed Al Abullah Al Sabah, said OPEC's markets monitoring committee would suggest to the group that output targets be held steady.
