I would like to hear more about break in oil, I have (2) brand new 657X'S getting ready to go in the boat. I have 2 Gal. of Amsoil DOMINATOR Synthetic that I plan on running in it. I was just going to use the Dominator for the break in oil as well, but if thats not the right thing to do then talk me out of it.
