There is alot more to a great oil than those 2 things. Obviously those levels could be less if one is using a roller cam. :)
 
Im sorry there is a misunderstanding . I wasnt stating that these things make or dont make a great oil. There has been much talk about this subject with charts ex. but no one states what is a good level of zinc and phosphorus is. Can anybody answer this.
Anybody with a roller cam Obviously this is not as important.
Thanks
