stupid question but do you have to use break in additive with a roller cam? is the additive for the whole motor or just for the cam? its gonna have oil put in it that has zinc

The zinc based additive is for flat tappet cams only and it breaks down rather quickly. It's added to the lifter bottom to aid in break-in of the lobe/lifter and needs to be changed out with the break-in oil no longer than a half hour of run time. Roller lifters require no break-in period....so to answer your question, do NOT add it to your oil for break-in and DO use regular dinosaur juice for the break-in. Hope this helps.
