For the first time in over a month, diesel fuel rose to a national average of $2.216 a gallon, while gasoline rose to an average price of $2.24 a gallon. According to the Department of Energy, this is the first time in almost two years that gas has been more expensive than diesel fuel. And as summer approaches, this might be a forecast of prices we’ll see through the season. It is predicted that both gasoline and diesel fuel will average anywhere from $2.23 to $2.27 a gallon, which compared to last summer, is an average of about $1.10 less per gallon. What a relief!
