Yes and yes ... but not by first hand experience. I have run mobile 1 in am Ram from the first change so I can't comment much on the difference before and after. The older 4.7 is somewhat prone to sludging. I'm not sure the new one has experience these problems yet but there is of course a time factor. Randy (our residence Dodge tech) has said (I seem to remember) that he has never seen sludge in a properly maintained 4.7 with with full synthetic. Plus if you have any tendency to miss the oil change window the full synthetic is good insurance.

Zonestar (I belive) once posted a really good guide to what is definition of oil by classes. It boiled down too the only two truely full synthetic oils commericial viable in the US are Mobile1 and AmsOil. If I can find the link I'll repost.
