Re: Dexcool coolant warning
 

I put Honda Genuine premix in both my Hondas, a 2002 CR-V and a 1999 Civic
HX. The Civic came new with green antifreeze, probably identical to the
Zerex Green that you can still get at Autozone, but I am not taking any
chances. Ten bucks a gallon for premix seems a lot, but that is enough to
change the entire cooling system in the Civic and a gallon and a half for
the CR-V. The bad part is I have to drive 135 miles one way to get it.

Afaik, Dexcool is for GM vehicles. "DEX-COOL is a registered trademark of
General Motors Corporation." What don't people understand about this?

The auto industry is seriously out of control on the coolant issue. I have
four different vehicles and this requires three different coolant types.
But if you mix and match or even try to save money by using a sensible
alternative you are looking for trouble.

More like chalk. When I was a kid they caught a dairy near me putting it in
milk, so it can't be that bad, heh.

I think you're confusing "silicates" (cleaning agents) with "silica" (quartz).
The former is in your dishwasher detergent, the latter at the beach.

Actually, I don't know that Dex-Cool even contains silicates:
