Oil prices slid closer to a new multiyear low Thursday because of growing doubts that the $789 billion stimulus package will reinvigorate the economy and demand for energy.

Retail gas prices, meanwhile, reached a new high for 2009 on Thursday and appeared headed back to $2 a gallon as refiners cut back on production.

Light, sweet crude for March delivery tumbled $1.96, more than 5 percent, to settle at $33.98 a barrel on the New York Mercantile Exchange. The contract has closed lower every day this week.
