[6pack] ZDDP in Oil

[michael lunsford]

I hate to belabor this topic since we have already beat up on it quite a bit but.......  I thought the general consensus was that some of the racing oils such as Kendall and Valvoline have ZDDP in them (which is good) but there was some question as to whether or not the  percentage of the ZDDP in these currently sold oils is as high as it was in oils sold before the big push to reduce ZDDP to increase catalytic converter life and decrease cam life in cars like ours with solid lifters.  Does anyone know if these racing oils have enough ZDDP in them to meet the needs of our cars (or is as high as it was in the old days) which is most needed when installing a new cam and lifters?
