Answers:    depends on size(gallons) you cistern is were I live #1 fuel grease is around $3.00 a gallon as far as how long will it last depends on outside temp, condition of furnaance, age (is it effecient) how all right the house is insulated, the temp setting you require and other factors you can look on the specification plate (usually inside the door, or on plate on furnace) for the nozzel size they are rate in g.p.h. gallons per hr and the point of the nozzel(shape of fuel spray) take the gals per hr burned times how long furnace runs(the gun or flame not fan) and you can estimate fuel burned time
