I've been using Pentofrost E for several years now as coolant on my 2009 S5.
Went to buy another bottle as my fluid level is low due to the coolant tank tube coming off, and Amazon will no longer ship it to my home address in California! WTF? They did so quite happily a year ago...
Looking at all the auto supply shops and even Walmart everyone says no longer stocked.
What are you guys using as a G12/G13 coolant instead?
If I can't get my low silicate preferred brand, I'll get what everyone else recommends instead.
Thanks.
