That's interesting. Before my last flush and fill this summer, I tried to wade through the coolant literature. All I wanted was a simple answer to "what is the best coolant to use on an iron block/aluminum head engine?" But with that question I had a couple of caveats: I don't care how long it lasts, I don't care whether it's poisonous or not, and I don't care about the mineral level of the water in Europe (because I use distilled water). As best I could gather, the answer was conventional green coolant with all the additives that they put in it -- it beats red, orange, yellow, etc. but it doesn't last as long, it's poison, and, of course, you should use distilled water with it. Now, mind you, I am not positive that I got to the best answer. There's a lot of bogus BS that is floated around on coolant, so I'm really not 100% sure. BTW, I bought AutoZone Conventional Green at nine bucks a gallon, and distilled water at the grocery store is a dollar a gallon. I also added WaterWetter, mostly because Bob P. told me to....
