It it safe to switch motor oil?

There's a very little bit of that, but a properly maintained engine should not develop a lot of sludge even with regular oil. Synthetic simply flows better and can get through smaller areas than regular oil can.

Ahhh... so a well maintained engine should have no problems then with those motor flushes? or are those just gimmick too?

As long as the oil is changed regularly and the engine is properly maintained, there should be very little sludge. Another big benefit of synthetic is that it can withstand higher temperatures than dino can.
