I think Mahle or Hastings bought up several ring companys.
I use both and seal power moly rings. For the few dollars more I run the molys.
I'm not talking about the old chrome bore your block out with each rpm type.
The rings I get will definitely be moly but what I was wondering was what is the difference between a Hastings Moly set for $95 and a Ross racing Moly set or JP Pistons ring set for $300 ? And what is the difference between Plasma Moly and just Moly - is it all just voodoo naming, because we all know how companies tart up their products with various names and claims when often they are the pretty much the same as their competition.
