I rent out of Panorama at HPN. They have all late-model C172S's - SP's,
Millenium Editions, etc... They have O-360, 180HP engines in there, and I
think the redline is also 2700. IIRC, they're supposed to get around 8.6
at 65%, and up to either 9.2 or 9.5 at 75%, depending on density altitude
and temp and all that... I could look it up for you if you want...

The planes are really nice - I like them a lot. And like I said, an extra
gallon/hr is going to work out longer than TMTBPS (Total Mean Time
Between Pee Stops) anyway. So I generally figure on 10gph and am happy to
have an extra few minutes to be sure.

That said, now that I have started my IFR training, I might have to be
more precise, since fuel planning is more critical, or should I say,
somewhat more restrictive...

What engine do you have in there? I burn 8.6 gph with my 160 hp O-320
and flight plan for 9. My redline is 2700 rpm, IIRC.
