Valvoline VST has adequate zinc, as well as most 'racing' oils. VST Synthetic is my choice.@PetroleumJunkie412 has done some study on the issue you are concerned with. I can't remember what his personal recommendations were or which thread he talked about it the most. Perhaps in his Keeping a Promise thread in the 4X4 Rangers section. He did talk about oil additives but I think that was more for cleaning the engine than increasing zinc content but I may be wrong. It may have been for both. 19Walt93 and Dirtman's recommendations would be worth looking into and might be the same.
YMMV, but if you value your camshaft, a high ZDDP/racing oil is a MUST.
