I am now gun shy about oil. I took out 2 wiped hydraulic cams out of my engines last year. One was a new comp cams and another was an older mopar purple shaft cam.

Next week I hope to fire up my new comp cams hydraulic lifer cam engine. I am going with the Driven (Joe Gibbs) break in oil and crossing my fingers. I need to ask Driven if I should add the Comp Cams additive or not.
