Skyking

the "wowing" IMO is either governor or fuel flows may be a bit off. I would at least check them to make sure.
at higher alt I have put on boost to low and readjusted mixture. Seems to settle engine on hot humid days.

re oil. did you not know they "monitor" the oil going into the jugs?

changing oil every 25 hrs is a big +++. AV blend, rislone doesn't matter. Anything to get the carbon down to a managable level including super lean when idle or taxi.

Let's not get onto the FAA/PMA issue! That's a hornet's nest. I am not about to suggest, recommend, or mention anything that is not "approved". Did you read the article on AVWEB (above) ?
