Anybody ever use water wetter in a 6.4?

I'd be afraid to try it while under warranty, but if that wasn't an issue, it might be beneficial.

It made a difference in my '04 f-250. I ran the diesel water wetter in that truck. I ran the same diesel water wetter in my '08 f-250. I'm getting ready to do a coolant flush - read up on it a little more - I'm going to put 2 bottles of the regular water wetter in this time. Apparently the diesel water wetter is meant for big rigs.
