I get 150knots at 10.5 gph,

Hmmpf. Gotta get me one of those Comanches. The Lance I fly burns 16gph
at that speed and I'm carrying two extra empty seats... Is that a
PA-24-180?

This is one reason I no longer lease back my airplane

I can think of several other reasons not to leaseback a Comanche - fuel
being the least of them grimace
