I'm kinda scratching my head here and wondering why there is still so much hand-wringing and so many people adding potions and buying the expensive Joe Gibbs and Brad Penn stuff when it has now been shown by the independent analysis (for those who didn't believe all the racers posting here or the Valvoline website) that you can just use the inexpensive, over-the-counter Valvoline VR1 and have more than enough ZDDP. As far as engine break-in, just use the Comp Cams or similar break-in oil or additive. Am I missing something?
