Oil Extends Gains, Eyes Growing Supply

Oil pushed further above $52 a barrel on Wednesday ahead of a U.S. government report that will show whether U.S. refiners are building gasoline stocks ahead of peak summer driving demand.

U.S. light crude edged up 29 cents to $52.58 a barrel, less than $6 below the record high of $58.28 reached early this month. Prices jumped $1.92, or nearly 4 percent in New York on Tuesday, ending a two-week slide.
