Definetly use EOS! Good stuff for break in. I actually used 2 bottles of when I did mine. Also, if you plan to usse Rotella, break it in on it to. Otherwise, any goos 30 wt (I use Valvoline) will do just fine. Remeber to change the oil and filter (if you had one) after the in initial break in. After that, you should be able to run just the oil without any extra additives.
