Thanks, Denny. I will seriously consider your advice about the oil type.
The advice above I am not sure I agree with, however. My Bonanza is
equipped with a turbo-normalized IO-520, something I may have failed to
mention earlier.

If the oil is not warm enough, the engine will most definitely overboost
two inches or more of MP.
