I am closer to joining the ranks of those who say any good quality
is silicate, sulfate?, and amine free, as many are, is ok. I think
many of the plastic
radiator ends gasket failing, the plastic becoming brittle
prematurely, and the
aluminum to steel dissimilar metal corrosion problems are passe.
But, how often do you change it, assuming you maintain the hoses,
etc, so you
don't do an unscheduled change in the middle of nowhere ? 2-3
years ? 5?
So, I'm not concerned about the price. I like the Pentosin stuff
from Germany and
have been using the 2 year Blue coolant equivalent to the OEM
originally in the S4/S6. The newer pink Pentosin is the OEM for
newer cars and is
called the "lifetime" coolant, but all other must be totally flushed
to avoid the brown
sludge of death.
There is a new VAG coolant by Pentosin that is purple --yeah, way
cool-- and mixes
with others. This is my choice now. I am not sure if it is
fluorescent or what, but it stands
out in a nice new reservoir. ;-) And it's good stuff too. G01 2A8
DA1 at $8 for 1 1/2 L.
See these guys for it by part # search: <www.autohausaz.com>
I don't know if the Audi and VW dealers are selling it here. They
are in Germany.
You have ~ 8 L of coolant so a 50% mix would require about a gallon,
or 3 of the Pentosin
1 1/2 L bottles with some reserve.
Most of the flushing/cleaning solutions require you to get the engine
warm and drain and
flush, so you need things together. Lots of fresh water afterward.
