I've been reading the POH for an older Piper Apache 150 lately and it
suggests pulling the prop through several times in cold weather. (I'm just
assuming to circulate some oil through the engine and prop hub, but then
again just how much would actually circulate when it's cold??) Although the
Apache has Lycoming engines, I too wonder if this is a carry through from
the radial days.

But the point should be, we need to try to elevate ourselves from the
50-year-old advice in those old references, and try to do what makes
sense today, with the advances in lubricating oils which were not
available when those old instructions were written.
