Just to not do a break-in on a new engine or even just a cam/lifter change with any type of synthetic oil, Mobil 1 included. After the break-in procedure with a GOOD break-in oil drive the car 500 or so miles then drain the petroleum based oil and change the filter. Then if you wish you can fill with your choice of synthetic or a good grade petroleum oil with a high value of ZDDP. Even Amsoil recommends using a dino based oil for break-in.
