A diesel, a gas turbine or a non throttled boiler has lousy part load fuel efficiency. Too much unused air swept throught the combustion chamber and out the stack without participating in combustion.
As posted on the "other" site. A five cylinder provides the vibration and noise of a four cylinder with the fuel efficiency of a six.

FYI I concluded I get a broader set of replies by posting my question on more than one forum. Answer your question: Which is more fuel efficient performing the same task the 4 or 5 cyl engine?? BTW I thought 5 cyl didn't vibrate therefore required no balancer shafts similar to a 4 cyl.
