The twice-monthly Lundberg Survey has found the price of regular gasoline has risen about nine cents a gallon over three weeks to $3.08.
The price of mid-grade gasoline is now $3.22 a gallon and premium is $3.33 a gallon, analyst Trilby Lundberg said Sunday. The U.S. average for diesel was $3.36, up 7.18 cents.
Lundberg says the highest gas price in the country was recorded in Chicago at $3.35 a gallon. The low, $2.73, was in Salt Lake City, Utah.
The survey was completed Friday.
