Wow, first let me backpedal. After doing some actual reading, @
stevesnj, I concede that DI and distilled water are not the same thing. That being said, I don't really care about the electrically neutral compounds that went along for the ride in the distillation process. ...yet. o.0
This has piqued my interest. I do wonder why Subaru specified DI water.
