Zinc Additive for Flat Tappet break-in?

I use the Hughes stuff and it works GREAT! It is a little pricey but damn sure a lot cheaper than wiping out an engine or cam.As the ol saying goes you get what you pay for! Hughes engine oil tech article #207 is very informative.It can help you make some needed decisions.Like I always tell my Wife ! CHEAPER IS NOT ALWAYS BETTER! So now she don't buy purses or shoes at Wallmart anymore! I don't use CHEAP OILS OR PARTS !! LOL
