Microfiltered vs distilled water for coolant mix

Hi All,

Can I use microfiltered tap water from the grocery store to mix with coolant for my Wee?

Or does it have to be distilled?

Thanks!

Distilled or deionized

Because there are many different metals and the radiator is very thin, any galvanic reactions based on dissolved minerals will accelerate corrosion greatly.

Micro filtering takes out large thing bacteria, virus, large organic molecules like from turds.

You can get distilled almost at any supermarket or just buy the pre made 50:50

PSST in ALL my stuff I throw in an amount of pump lubricant and corrosion protection

Or just buy a gallon of pre-mixed Zerex Asian Vehicle Antifreeze/Coolant, use half, and share the other half with another strom rider. This is 5 year antifreeze.

My local grocery store did not have distilled water. After reading the ingredients of other drinking waters, it turns out they contain salt and other chemicals I probably would not want to put in my radiator. I would use tap water before bottled drinking water...or like others have said, just use the 50/50.

And it all depends on the minerals in local tap water. Some waters work fine, others are harmful, and taste doesn't always tell the story. When we needed boiler water for the ships' boilers and were short of distilled water on board, good tasting San Francisco water had more minerals and was worse for the boilers than nasty tasting L.A. water. After we got the boilers fixed and steaming, we then needed to repair the distillers that distilled fresh water from sea water...then blow the boilers down and replace that water with distilled water, adding boiler treatment chemicals all the time..... This was years ago with 450 psi or 600 psi boilers, a history lesson.

Deionized water works as well as distilled water for most of these types of uses--coolant mix, flooded cell batteries, etc.

Yummmm.
I have a reverse osmosis system in the kitchen, works fine for me!
Really though, 50/50 is pretty darn easy, if that's what you're looking for.
I did use the mighty Columbia river to fill up my old Chevy Blazer a few times though, haha. Had to part ways when I moved...:bom_bigcry:
