Some of these Rams have been having wear and metals especially when new. It might be a good idea to change your oil once with conventional for a run. When your engine is new, you want to encourage wear for the first 3000 or so miles, soften all the "sharp" edges. Synthetic oils discourage wear much more then conventional oil. So the traditional train of thought is not to switch over to synthetic for 3000 miles. Top tier oils even say on the bottle not to use for the first 3000 miles.
Can you? Yes you "Can" switch now and never know the difference. But if you want cheap insurance, do a quick change for another 1000 or so miles. Also, make sure to use Royal Purple filters with that oil, they are the best around.
