It doesn't take much of a USENET search to see all the
badmouthing about Peak antifreeze, I guess mainly because
the brand contains phospate. People say this and that,
and repeat what others say without much thought.

I have visited the Peak site and they discuss these issues,
and what they say makes sense to me at least. People blast
Peak because of the phosphates, then turn right around and
recommend distilled water for cooling sytems (which apparently
pretty much removes any negative effect from the phospates).
The Peak site claims that some European car makers say to avoid
such antifreezes simply because Europe generally has much harder
water than the U.S....makes sense to me.

Read it for yourself: http://www.peakantifreeze.com/tech/tech_b.html

Maybe I'm naive, but how could they legally make the claims on this
page (http://www.peakantifreeze.com/peakanti.html) about their
standard product if it weren't fact anyway?

And yes, I changed the coolant in my German car today, and used
50/50 Prestone and distilled water, but have used Peak for years in
my cars with no problems.
