No. 2 Diesel Fuel Prices Hit an 18-Month High

It could be a long, hot and expensive summer for heavy-duty pickup truck drivers. The average price of a gallon of No. 2 diesel fuel in the U.S. has reached $3.122 a gallon — the highest price in 18 months, since it was $3.088 a gallon on Nov. 3, 2008, according to the U.S. Energy Information Administration.

While that's significantly below the July 2008 peak price of $4.76 a gallon, it's the 10th week in the past 11 weeks that the price of diesel fuel has climbed. And a in the Gulf of Mexico isn't helping things.

Diesel is most expensive in California, at $3.26 a gallon, and cheapest in the Gulf Coast region at $3.083 a gallon.
