Bob,
In order:
1. 40 weight oil is 40 weight oil, does not matter what type.
2. Do not have to flush.
3. We put Mobil 1 oil in from the start, no problems. GM does it on the Vette, why not everyone else. The old wives tales about rings not seating are just that. If the cylinders are correctly finished, the rings are seated on the engine stand.
