Wow! Since I haven't the slightest idea why that would matter, you
need to explain to me why this should be done in this, a very
unscientific and casual comparison.

I did go back and check the data, the trip was 544NM. So I guess I'll
restate that I was throttled waaaaaay back so as not to run ahead of
the Mooney, he was firewall forward to keep up with me and on both
legs I burned about 10 gallons less than he. He has the 200 hp engine
and I the 250 hp engine. Extrapolating the memory, it took me about
$25 less in fuel to make each trip than it did he. I probably could
have used the same fuel and arrived about an hour before, so the
potential owner needs to check his mission profile before making any
decision. But for $45K, I would look hard at that Mooney.

Al,

Well, there was up and back with almost exactly the same results.
Does that count?

No ;-) If instead you would have switched and operated each others plane
with the same engine/mixture management you use in your own: maybe.
Determining the efficency of an airplane needs time and skill if done right.
