No, no flaming. You do have a point.
I happen to believe, as others above, that 2 engines running at lower power levels and properly leaned for economy per the POH will give more range than one engine. But you can certainly extend the range even more by leaning further and operating lean of peak (LOP), if you have the proper equipment and conditions.
There's another thread on this message board about operating LOP at
http://www.337skymaster.org/messages...&threadid=1208 but here's an excerpt from there on what you need:
"Those who are technically astute (you don't have to be an engineer or a mechanic, just someone who is technically inclined and understands the subject), who have installed GAMI injectors for smooth operation across all cylinders at LOP, who have cylinder-by-cylinder engine management/monitoring equipment, who are willing to to give a bit more attention to engine management in flight, and whose engine is no longer under warranty can run LOP at cruise."
Of course the cost of the GAMIs and the engine monitoring equipment, if you don't have it, is substantial.
