COLUMBUS, Ohio - Oil prices pushed to new highs for the year yesterday on a weak dollar and new data suggesting manufacturing in China has strengthened. Both of those factors helped send energy prices to record highs last summer.
The national average price at the pump this weekend rose above $2.50 for the first time since October. In Massachusetts, the average price for a gallon of self-serve regular rose 8 cents to $2.44.
Benchmark crude for July delivery rose $2.27 to settle at $68.58 a barrel on the New York Mercantile Exchange, the highest close since early November. Natural gas futures soared 10 percent.
