Hmmm, My BS meter is twitching...This is a BSFC of ~0.142

The very best diesel BSFC is the huge japanese engines used in
container ships at roughly 0.30...

Well, here they're saying somethign quite different

The 3 GPH might not have been at econ cruise, but it was probably at max
endurance, i.e., just enough to keep them aloft.

And the Wilksch Airmotive numbers for specific fuel consumption are
resoundingly unimpressive for a diesel. It sure is light though!

Not sure if you are being sarcastic about the weight, but you do
realize the weight was in kilograms, right? 127 kilograms = 279
pounds, which is pretty heavy for a three-cylinder engine.

No it isn't :-)

Jet fuel is about 6.8lbs/gal. 3gph is about 20.5 lbs. SFC for a
turbosupercharged diesel is considerably better than the 0.5 used for
normally aspirated gasoline engines. Even the old Packard radial
diesel did pretty well in the SFC department.

Based on the available data, the figures are credible, in my opinion.
