The '67 182K I fly typically trues a good bit slower (~120), but I get much
better fuel burn. I'm typically burning about 12.5 gph at that altitude.

Lessee... 422nm trip @ 147 knots and 15.5 gph = 2.9 hours and $200 (no
wind and 100LL @ $4.50/gal). Same trip @ 120 kt & 12.5 gph = 3.5 hr and
$197.

Three dollars to buy 30 minutes? Tempting deal.

That's about the same mileage as Mobile to Houston, a frequent trip of mine.

In my airplane, that's 422nm/135KTAS = 3hrs 7 min. * 10.5gph * $4.50/g=
$148.00.

Hmm...$52 more to save 13 minutes. Not very exciting, but then the Skylane
is a much roomier ride than mine. Comfort counts.


My real question is: What power setting were you guys using? I'm usually in
the 65-70% range during cruise.


I believe it was 75% power, 23 X 2300, 25 deg. ROP.
