Your break-in strategy is sound - just do what Lycoming recommends.

The cold-start advantages of a mult-vis are tremendous and the new synthetic
oils are superb with the latest corrosion resistance packages. PAE isn't
terribly cold, but at startup, all ambient temps are cold enough for a
multi-vis to pay off big. It's simply a MUCH better all-around oil for
private owners.

Do they make multi-vis mineral oils? You certainly don't want to be
dumping Aeroshell 15w50 in a new engine until after break in.
