Best Antifreeze for Volkswagen Passat

I've always used the Pentosin equivalent in all my Volkswagens and Audis. Pentosin E/SF. Pentosin SF is G12 (pink) -2005, Pentosin E is G13 (violet) 2006 onwards. Safe to mix with factory fill, of course can always go to the dealer for coolant too. These are concentrate, so you do have to mix 50/50 with distilled water though

I have two gallons of this I've used in my 2009 B6 Passat that is leaking coolant. I don't drive it much, just once in a while. I just don't have the funds to fix the leak, which is likely the water pump. This coolant works just fine for me!

Prestone destroyed my passats Cooling system, everything just deteriorated, the hoses in my car started to break up. I don't recommend prestone
