I got an engine being built and I wanted to see some opinions on how you all would break in the engine.. Also What oil would you use for the initial break in period. I bought just regular Mobil 5w 30 conventional and got some Lucas Oil Break in Additive would anyone recommend that usage? I read on the back of the Lucas bottle that it says may cause catalytic converter damage on "post 1994' vehicles.
