I would not hesitate to change directly to Mobil 1 synthetic immediately. Of course, a filter change is expected. I don't think a flush is in order for your engine, as the mileage is quite "young", and the synthetic is completely compatible with regular motor oil.

Never drive a car with an engine flush in the motor! It's not the gaskets you have to worry about, it's the reduced lubricity and solvent characteristics of the motor flush not allowing proper cushioning and lubrication under load! The only exception might be using a quart of ATF as an engine flush to utilize the detergent qualities of the ATF to clean out the varnish build up in the motor on a higher mileage car that may have had neglected maintenance.
