The Porsche coolant is about $30/gallon undiluted. You can buy some and cut it 50/50yourself with distilled water. A little cheaper solution that will work is Zerex extended life GL-5 IIRC. You can find it at Pep Boys and it, like the Porsche stuff, is not diluted. I think there's Pentifrost product but I don't know anything about it.

Thanks. I only mentioned the premixed because I saw it on the shelf. I can mix my own, for sure. I just didn't know if there was a certain non-Porsche brand that is/was recommended. The nearest Porsche dealer is an hour's drive from my house. I'll check locally for the Zerex. Appreciate the tip. Thanks!
