Antifreeze VALVOLINE or OEM Volkswagen

I always use g13 from the dealer mainly because they can void any warranty for repairs on your cooling system if they see there is not g13 in there (g13 is pink, other types are purple) and with a model that is known to have coolant system issues, i aint giving them the excuse to not fix something they should.

Only use modern Volkswagen G12evo coolant! This is required not optional, if you mix the wrong coolants you can create an acidic meta eating coolant mixture that will ruin your engine

I use Valvoline's Zerex Asian Blue prediluted, it works just as well.

Zerex G40 is pretty good. Made by Valvoline and has G12++ spec.

I went with Valvoline Xerex G40. BASF G40 is the equivalent of G12++. Valvoline/ZEREX G40 Euro Pink coolant meets this newest worldwide standard BASF G40 and German standard VW G12++ .

Brands I recommend are of course Toyota OEM Super Long Life coolant and surprisingly Walmart Asian Red Super Long Life coolant (actually comes out pink ) has never failed me and I offer that as an option to my customers. Then there is the Valvoline zerex Asian I don\u2019t highly recommend this coolant but it does work just not that well from my experience.

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!

I run it in my 2010 Tundra. after much research and not wanting to spend the $$ on overpriced toyota branded coolant I swapped out the system when I hit 100k (Valvoline asian). That was maybe two years ago. 30k miles later no issues.

I'm flushing our 14 Tiguan this weekend cause the coolant is nasty as hell.

I also had the coolant replaced. I asked for the OEM stuff, which I guess is pink (?). They said mine was pretty much black !
