jeffies, give it up. you merely make yourself look a luddite.

modern, water-cooled, 4-cycle, brand spanking new diesel engines in laboratory
conditions use about 1 gallon of fuel for each 16 hp produced.

Now you're using de-tuned farm engines to prove your point. But once again,
you
screw it up! On the same page they list others that are over 18 hp/gal-hour,
and that's detuned to run at 1500 rpm, and using US gallons. Those numbers
listed as "Specific Fuel Consumption" is in "grams per HP-hour"; you have to
be
capable of a bit of math to properly convert to hp-hours/gallon.

old fart, here is the Lister engine under brand new engine, and laboratory
conditions claiming about 19 hp/gallon/hour (that's Imperial gallons, btw)
