Synthetic Diesel motor oil

Sometime back I contacted Royal Purple and they confirmed that their oil is a Group IV and Group V mixture of synthetics. They also stated that a CJ4 oil may be better than a CI4+ oil when you are comparing mineral grade oils due to the better base stock in the CJ4 oil. HOWEVER, the CJ4 oil (in 2006 and earlier) does not offer any advantages over Royal Purple due to the superior base stock in RP - especially for shear stability.
I also read on BITOG Forum (Bob Is The Oil Guy) that the BEST oil for high temperature shear protection in the 6.0L is the Red Line oil. the question is - how much is really needed if you change the oil at 5000 - 6000 miles???
13.5 qts Royal Purple - apprx $85.
13.5 qts Red Line - apprx $115
13.5 qts of Mobil 1 diesel oil - apprx $80 (might find it a little cheaper)

To meet the demanding requirements of today's
specifications (and our customers' expectations) Mobil 1 uses
high-performance synthetic fluids, including polyalphaolefins
(PAO, groupIV),
along
with a proprietary system of additives. In fact, each Mobil 1
viscosity
grade uses a specific combination of synthetic fluids and selected
additives in order to tailor the viscosity grade to its unique
requirement.
Mobil1 motor oils are 100% synthetic and offer the best overall
protection and performance in the real world. Consumers need to focus on
end performance not how we or any other petroleum manufcaturer gets there.
