When talking about issues are you talking about foaming issues with the Rotella?
If so, like you pointed out, the 6.4 does not have an oil fired injectors like the 6.0 has. You won't have any problems using it in your 6.4.
Yeah.
When dealing with the problems of the 6.0 our Ford dealer claimed the high operating pressure in the HPOP would foam some oils due to detergents in the suspect oils. We changed because we were at our wits end with that 6.0. We have had better luck with the 6.4L so I was tempted to change back. On an $80 oil change the difference is about a $5 savings with the Rotella. I have some old stock that I found during a recent shop cleaning and was debating using or giving it away.
The difference in price isn't really a driving factor but sometimes the Motorcraft PSD oil is hard to find whereas Rotella is everywhere.
Now my next problem is finding someone with a waste oil shop heater that will take 300 gallons of used engine oil. Hmmm.......
