OK who is switching to synthetic lubes in the Challenger?

If you are or have experience in what has worked in other SRT's (e.g. Charger), please fill in on process - break in XX miles on petroleum lube, flush with YY, put in zz synthetic lube, etc.?

I used Mobil 1 synthetic in my Conquest TSI (87) and it sure kept that engine and especially that Turbo running like new (oil always looked golden).

results of synthetic lubes on other fluids (trans, rear, brakes, etc.)
