I have summer home in PA with an oil furnace and one of those big oil
tanks. See it at - www.harry.everhart.com. There is a picture of furnace
- you will surprised how small it is. It burns maybe 300 gallons a year.
My "friend" had a VW rabbit diesel. He even had a spare fuel tank in it
where the spare tire went. He carried 30 gallons - went about 1000 miles
between fills. He was caught.
