Oh, I don't know......I guess I read or heard somewhere that it's best
to have full oil for best cooling and efficiency, but I'll run seven
for now and add at 6.


I found that even that was a little too much for my O-360. I add a quart
when the level falls a notch below 6.

Likewise IO-360 in a Mooney. I used to add at 5 on my O-360 in Archer. I'd do
that in the Mooney, too, but my partners want to add at 6, I fudge a little and
add at "a notch below 6".
