Just curious, because its allot harder to get stuff in Canada, is there a coolant that is not from the porsche dealer and readily available for purchase that is okay in the boxster cooling system?

i used Prestone Max european .. it says good for Porsches from 2010 as that is when they switched to the G-12 type coolant.. I flushed mine so decided to go this route..
I guess time will tell if it was the right move.. takes a ton of it though ...
Got this off the internet.. but who really knows ... i guess if you want absolute Guarantees, take your wallet out and go to Porsche .. im wondering if Porsche Branded coolant is the original green from 2001 or if they will sell you the new purple stuff anyway. edit: I just read Porsche sells a "G-40" that is rated for all water cooled Porsches .. so there you go .. even Pelican lists it as compatible for Boxster S. i think i will be fine.
