Reasons for rings not "Seating"

[Goat Blower]

It means that the rings are holding up the proper compression in the cylinder and not allowing oil blowby in the crankcase, basically isolating the two to a degree. Mahle is a good piston, they've been around forever even supplying to exotic OEMs.

This topic has been beat to death here, but you want a decent 45 degree hone, use regular non-detergent oil for break-in, and follow the procedure of your choice. Ring and piston to wall gaps being correct should be a given.
