You didn't have an answer for me, whatever. In my experience pistons rarely wear out. Sometimes they they wear out the landings, but most often something happens to them to destroy them e.g. ran lean, overboosted, over-speed melting, etc.

I thought maybe BMW pistons had some high tech property which made them wear out- like those nikasil cylinder walls or something.
