Looking for more reasonable coolant. Will the vw coolant work with our porsches?

I use VW's G12 coolant in my Turbo. Same stuff that I put in my Audi. It's phosphate-free coolant, that's the most important part.

Short, Yes.

Just wondering cause the people who bought the item from amazon says its actually not g12 anymore but the more updated g13 fluid same color.

Don't you have a relatively new car? Why do you need coolant?

Luxter

No idea, haven't followed VW specs that closely. If G13 is backwards compatible with G12 then I suppose you are fine.
If not however.....
I still can get G12 Pentosin SF from my local store.

Thanks for the info luke, from feedback of customers who made the purchase, some say g13 is the new g12and they say it is reverse compatible but they are all referring to their vws not to porsches.
Hi alex, yes its relatively new and i actually had the cooling system serviced due to a leak, under warranty. All the coolant is new but i am going to install the thrid rad and will surely need some coolant

Post # 8 in particular:

"I did quite a bit of research on G12++ vs G13. It appears that they are really the same thing, but G13 is produced in a slightly more "environmentally friendly" manner. It seemed to start out as Europe-only and Skoda brand only.
From this research-
Here’s some interesting info from a Skodaparts.com site:
G13 coolant additive provides the same exceptional cooling and antifreeze performance as G12++, but is manufactured in an environmentally sustainable way, using glycerin instead of glycol. Glycerin, a bi-product of biodiesel production, is much less harmful to the environment than glycol-based products, which are produced from mineral oil. In comparison with the manufacture of traditional coolant additive, it is estimated that G13 production will produce 11 per cent lower CO2 emissions.

So there is a difference in manufacture, but it may not matter in actual use, and the final product may be identical. What I suspect is that VW isn’t yet able to produce enough of the G13 to supply markets outside of Europe. It could also be that different markets use coolant sourced from different suppliers, and suppliers for the US aren’t yet capable of producing the G13"

That is great info luke. Thanks brother

So Porsche coolant is the exact same thing as the vw coolant?

Luxter

Not the same. They are miscible though.
