Look up the Lake Speed Jr. videos. A lot of people do not realize that it is not just zinc and phosphorous. The other additive packages changed, but more importantly, so did the detergents. It's quite often the detergent package that is hurting your cam. And you CANNOT just throw more zinc, phosphorous, or moly in that oil to "fix" it.
