OK, so I have been admonished by the grand poobah of all things audifans
that my survey is a highly subversive activity, the result of which will clog up
the audifans bandwith generator forever.
There have already been several posts (4 Posts) reporting on the use of the
Prestone Orange. So far, millions of miles logged (at least a third of those
million miles have been by me) and not one respondent with a Prestone Orange
Coolant-related failure in their Audi.
Further, I spoke to someone at Prestone. Their coolant is dexcool-approved,
not the original dexcool antifreeze that GM started using in the 90's. It
is free of phosphates and silicates (as, apparently, is the new "universal"
extended life coolant).
To his knowledge, Prestone is not involve in any of the ongoing litigation
regarding factory-filled Dexcool Antifreeze. Prestone only became an OEM
supplier for a small number of cars in 2001, and are not aware of any problems
with their coolant and GM cars. Most every complaint that had been posted was
for late 90's vehicles.
The Prestone customer service rep I spoke to put the orange extended life
coolant in his SAAB, and drove it over 250,000 miles with no coolant-related
problems. He assured me that this product has been tested as safe on all
materials currently in use in cooling systems, include those used by Audi.
The original green formula may be of concern to Audi Owners, as it indeed
contained phosphates. But, I suspect that the new universal extended life
coolant (more of a yellow-green and reportedly phosphate-free) will do just fine
in our cars. There is a possibility that this is the coolant used in the
original poster's car, so this whole shibang could have been for naught.
An interesting note is that much of the concern with the GM DexCool coolant
has to do with contamination of the coolant. GM adds a stop-leak to its
vehicles, in addition to the coolant at the factory. It is entirely possible
that blocked passageways, deteriorated gaskets and overheating are what causes
the factory dexcool to fail. Who really knows.
I have no desire to turn this into a torsen-like debate. However, I want to
be exposed to real life experience with what is apparently a controversial
product -- mainly because I would like to know if I (and many other Audi
owners) have a defective product circulating in my car.
The unofficial survey has been concluded. Please post individual results at
your own peril.
That is all.
