What antifreeze/ coolant are you using?

Just wondering what is good out there. I have a mishimoto aluminum radiator if that would help on my coolant quest

I used to believe all the hype about distilled water, but now I'm really on the fence about it.

Some experts now say that distilled water does more harm than good because it can strip all the electrolytes from the metals. I've seen aluminum radiators that have become porous and it's not pretty.

I figure the risk of having calcium deposits in my engine are a lesser evil than having holes in it. Besides, how much mineral material could there be in a gallon or so of water? It's not like my hot water heater which may see a couple hundered gallons pass through a day.

I like to run tap water, and a little less than half store brand green antifreeze in summer, along with a bottle of water wetter. In the winter, when the car sits in the garage, I run at least 50% antifreeze.

Just run premixed then. I wouldn't run tap water.

I'm going with this when my build is done. Seems like the best stuff out there, worth a try to me especially if it doesn't get hot enough to boil and you can open the cap after driving any amount of time.

30% antifreeze. 70% distilled water. Water Wetter. I am in southwest. I don't worry about freezing temps.
