[V8] Audi antifreeze, peak or prestone or?

[toml99 at todomundo.com]

TDS coming out of my tap(city water) in Bellingham is around 50(with  
the clorine)...but I still buy distilled to fill up the car/truck.  I  
got 3 gallons of G12 for $15/gal from a guy awhile ago(out of the  
back of his van in a mall parking lot), and as soon as I've got a  
free day, will drain the moderatly fresh Dexcool out of the truck and  
be done with that now that it's out of warranty.  Peak's "lifetime"  
coolant is very similar to Dexcool and I've read/heard about enough  
Dexcool nightmares to just want it gone.  5-speed is still Blue, and  
Lago recently got the G12+ that Blau sent with the timing belt kit  
and switched over from a lifetime of Blue.  There is no corrosion  
anywhere and I'm a believer.  The Grey car had green in it when I got  
it, and had tons of corrosion/all new radiator hoses(bonus) even  
though it's only got 125K......
MERRY CHRISTMAS Y'all......Sincerely, Tom
