My unscientific opinion is this:
1. A lot of contaminants exist in the system regardless of coolant type. Casting residue, metal flakes, solvents, etc, etc.
2. No antifreeze lasts forever- though the manufacturer acts like it does.
3. Tap water is full of crap. I only use distilled.
4. Bypass coolant filter is cheap insurance.
I use dex-cool b/c it doesn't mix with green stuff and I figured I never get all the coolant out of anything I ever tried to so I figured some would mix and turn to sludge. I put the filter in, and filled it with junk in a week. On my second filter and the coolant looks pretty darn clean. I'm sold on coolant filtration. The mount cost me like $35, the filters are like $9 or $10.
As far as what type of coolant- whatever floats your boat. I never had a dex-cool problem personally, but I heard plenty of stories. My guess is the stuff was contaminated with something from the factory and sludged up.
The parts guy from Detroit dealer I go to uses whatever Detroit uses and tests it and uses the 'charged' filters in his Dodge Cummins. I'm not ready to go that route, as I never read of 6.5 cavitation problems. Plenty of other block problems, but cavitation didn't seem to be one of them!!
