AT ALL?
I have a decent conductivity meter at my workplace to assist managing our greenhouse water. I've played with it a bit while trying to "super clean" an engine cooling system. While distilled and DI water have trace amounts of conductivity, I could NEVER even begin to get water out of the "super cleaned" engine coolant system to show low amounts of conductivity (low ion, pure water). This tells me that the engine components release atoms immediately into the pure water, it reaches an equilibrium level almost instantly, and barely a trace of any metal, rubber, etc. atoms are eroded away from the engine parts.
Other greenhouse growers claim that DI water running through pipes in a NON circulating system do show signs of erosion after years. The continuously flowing super clean water strips the atoms away in a very tiny amount over a great period of time. That's what they "tell" me.
The water in an engine recirculates, so any tiny amount of atoms stripped off the engine surfaces stays in solution, reaches an equilibrium level quickly, and ceases to erode any more atoms.
That's my opinion about the subject based on playing with a conductivity meter. I cannot imagine distilled water recirculating in an engine is going to erode any amount of material to even think about engine damage. Trying to claim distilled water is worse than DI has me scratching my head also.
That No-Rosion site seems to be hawking something that may have assisted with the very old conventional coolants. Their play on inducing fear sets off red flags for me. It seems similar to the Lubegard transmission additives. Very high quality additives in their day, but are they really beneficial with today's sophisticated transmission lubes?
THANK YOU for that insight.
I am NOT a believer in their marketing hype, nor their fear mongering, but was only trying to bring up another('s) stance/given explanation for using RO/DI over distilled, to be discussed and refuted or confirmed.
