I cannot speak for the brand new motors as motor technology has changed a lot just in the last few years but synthetic has always been a huge no-no for BREAK IN oil. The simple reasoning behind this is that because synthetic oil has so much more lubricity it prevents the piston rings from seating resulting in a loss of compression. I have built several motors and believe in using dino oil for break in and then switch to synthetic after break in is over.
