Thanks for such a practical idea; I hadn't thought of displacing the air in the tank itself.
For lack of a MIG welder I could just exhaust my 1984 turbodiesel into the tank to displace the air, couldn't I? It reminds me of the old technique for ridding one's yard of gophers... Not being a chemist, I am guessing that automobile exhaust from a turbodiesel would contain more carbon monoxide than carbon dioxide, plus a bunch of soot and other particulates. Other than the temperature of the gases, would the chemical composition of the exhaust fumes degrade the oil more rapidly than the air being displaced?
