I would use Mobil 1 in the grade called for. There are pics on this board showing motors with many many miles run just on M1 and no sludge. Plus from what I have read here synthetics will clean an engine over time. Also with the M1 you could go 6k OCI easily to lessen the cost compared to dino.
Synthetic such as mobil 1 or a diesel synthetic such as rotella 5/40. What would prevent sludge better? My manual states a 10/30 would I be ok with a 5/40.

I'd go with an HDEO such as Delvac 5W-40 or 15W-40, and 5000 mile OCIs.
jessealan, sounds like either way you prescribed will provide clean, trouble-free service for a couple hundred thousand miles.
I suggest using M1 every 4-5K just to make things a bit easier. Peform a couple UOA's to put your mind at ease with whichever path you choose. I'm sure you'll be satisfied either way.

Not sure but I here Red Line & Synergyn oil do a good job cleaning.
