Another round of fuel increases on the way

Americans can brace for a 30-cent jump in the price of gasoline and a 21- cent hike in home of heating oil prices by this time next year, says a preliminary forecast prepared by Energy Department economists. The 207-page draft study from the agency's Energy Information Administration forecasts regular leaded gasoline selling for as much as $1.52 a gallon and heating oil going for $1.14 a gallon in the first quarter of 1981. Current retail prices were estimated at $1.22 maximum for regular gas and 92.3 cents maximum for heating oil.
