20W50 Full Synthetic Oil

Anyone switch to synthetic? Any thoughts on it? Was thinking of going that route based on the manual stating it's recommended. If so, how soon after break in do you switch?

I am going to try 15W-40 Rotella T5 synthetic blend this winter. Engine should start easier when the weather is on the cold side. 6000 miles on unit.
