Well that is what I figured all along Bill after all taht pic was made for me since I did not know that we even had any hydraullic lifter---I though it was all solid---anyway soundz like high zinc is good for the engine and bad for the cats---hey though plugged cats is no biggie to fix vs a worn out engine---so do we all think it is best to use the additive by gm for break in all the time now when ever we change the mobile 1 synth oil??? an extra 12 bucks is not a big deal when the oil change is high $$$ to begin with--- would be nice to have the tuners chime in with their two cents worth!!!
