Mixing G12 Coolant

turtleboy · #1 02-16-2010, 08:14 PM

I've done some searching, but wanted a definitive answer.

What are the differences between the different G12 coolants, and can you mix them? The ones I'm talking about are G12 (pink), G12 plus (purple), and G12 plus plus (purple):

Yes they can be freely mixed. I don't know why you'd be getting different colors though.

Valvoline just updated their G12+ in '03 and had the purple color. Pink is the OG after G11 but some people confused it with GM's Dex-cool, hence color change.

Pink/Purple are compatible, as long as they're the Pentosin/Valvoline G12 mixes.

Agreed, any of those can be mixed as long as it says G12 on the bottle.

where at? like autozone or online only?

Manufacture only. It's not like Audi built it's own factory and line to produce coolant.

Thanks for the info guys.

Does anyone know the difference between the G12, the G12+ and the G12++? Is anyone better than the others? Or are they all pretty much equal?

They're updated coolants IIRC. I would just get the cheapest/easier to obtain. Really not any difference. Newer cars use purple, older cars use pink, but neither harm the other. B5 TB kits use Pentosin pink G12. B6 TB kits use Zerex G12. Zerex is a division of Valvoline.
