*>    The "solid oil" problem crops up in more conventional aircraft in

In the book about german ace Erich Hartmann, a captured
russian pilot showed the germans how to keep their air-
planes startable in the frigid temperatures. The technique
was to mix gasoline with the oil! Apparently, after the 
engine warmed up sufficiently, the gasoline boiled off 
or evaporated. Do they make multigrade oil for airplanes?
Or can you use Mobil 1?
