I could say that about several brands. I have seen plenty of motors come apart with very clean internals and none of them had Royal Purple in them. I understand that you like it but I have seen plenty. As a matter of fact I pulled a motor apart last week with over 100 hard passes on it and 30k daily driven and it was as clean as it was new. That oil just happened to be Castrol GTX.

I know it use to be but I was under the impression that this was changed early this year? Maybe not but either way I will keep using it since it has proven itself just fine here.
