[Slowplane]

I've been using distilled water and soluable oil in my radiator and engine since rebuild. (New radiator and engine rebuild 5000 miles ago).
Now I understand that soluable oil ain't necessarily the way to go! (water jackets get "oily")
I'd like try this Zerex product with distilled water. No need of Antifreeze here in San Diego.
Any comments/criticisms, alternative or better ideas??
All is appreciated; Thanks Jeff
