Has anyone else seen this anti-freeze.  I am far away from any Porsche dealers and have not been able to get any antifreeze locally for my Boxster.  I did a search at autozone and they recommend this antifreeze.  Does anyone have experience with this?  I have posted what they have on their site for easy reading of what I have read.
