Also a very real thing we learned comparing our real world spreadsheet post-ownership to local rental prices -- there's a 182 on the field that rents consistently below what we can operate ours for.
It's a good deal for a number of people who seem to fly it quite a bit (we hear the tail number in the air often) but we always wonder whether someone is eating the roughly $10/hr difference and doing all the maintenance properly, or if there's "too much being deferred" in it.
Frankly, I've never flown it nor looked at flying it. I just know they're renting it cheaper than I can safely operate mine, and we aren't super fussy about cosmetics but we do anything safety-related.
So be careful when (over) analyzing rental to ownership prices and remember that some rentals for whatever business or circumstantial reasons (maybe the leaseback owner is an A&P and doesn't charge him or herself for their own time maintaining it) can be offered for a lower per-hour rate than you'll *ever* be able to operate your own aircraft.
Just sharing for something for the brain to munch on. If you see a rental price that's "too good to be true", when looking for numbers to compare to... it probably is.
That rental price gets worse if the aircraft is used to go places and hangs out below 5000 MSL.
We've noticed a clear trend in our 182 operating costs that our fuel here at high altitude at home runs a consistent 11.5 gal/hr. At lower altitudes on trips the average fuel flow rises to 13 gal/hr of course.
Properly leaned and power set properly at both, you're just going to get more ponies out of a non-turbo/supercharged engine once you give the poor thing some air. Especially a big fat O-470. You also get a few more knots out of it, but thats a diminishing return.
Co-owner noticed it in the numbers for his OSH trip again this year. Stuck under cloud layers below 6000' MSL, it matches the book.
