A friend of mine has a Piper Cherokee (840 statue mile range on 36 gallons, which I take to be about 23 mpg at a cruise speed of 124 mph.) Because it's carbureted, there's a lot of fiddling with the mixture to get it to run properly at various temperatures and altitudes. I would imagine that it would be a little more efficient (and a lot cleaner) if it were fuel injected.
Still 23 mpg at 124 mph is about the same as my Saturn gets at 83 mph. Not too terrible for the speed. :-)
