Need to decide between the two and best application strategy.
I know they are both good, but I have heard that WW causes brown stuff in your coolant and that just doesn't sound good. If Royal Purple is just as effective without that sideeffect, seems like a no brainer..
Also - 50/50 is the universal coolant and will protect to virtually near absolute zero (not really, but you get my point). However, it seems to me that a 60/40 solution upto a 70/30 for areas like Seattle where it does get a few degrees under 30F... but not by much, should be ok. I've also heard - and tested (not on tthe NSX..)- that because the coolant is under pressure, running straight watter will not freeze even a few degrees under 30F.
Water is after all, a much better heat transfer property than glycol.
Lastly - anyone try RMI-25 as a cleaner in their NSX?
Thoughts appreciated.
