G12 and G12plus ..........

The additives are what is important. Any formula can be dyed any color. The dye has no function
other than to differentiate the stuff outside of the bottle (and to alert when you mix two different ones together). The ZVW stuff is a brighter pink than the stuff Mark P has pictured. I can only go by part numbers. Also, G12+ can be mixed with G12, but not the other way (you can't put G12 in a car that came with G12+, but G12+ in older cars is fine, in fact better). Hope this is making it clearer and not more confusing!

Now it gets interesting. I have a bottle of 3 different G12's at home and just checked them out...
What I have is a 1 gal jug of ZVW 237 G12 purchased in late 2000 or early 2001, a 1.5L bottle of Pentosin brand G001200 coolant purchased in 2003 (via the web, can't remember where) and a gal jug of the G 012 A8FA4 just purchased a few weeks ago.
The ingredients on the label for the two gallon jugs are identical, but the ZVW one is an orange-pink color and the G 012 A8F stuff is a pinkish-purple (both are concentrates, as is the Pentosin stuff). When you mix these two VW/Audi branded gal jug coolants together , there is a definite color difference. But, the Pentosin stuff is the exact same color as the G 012 A8F stuff, and the label ingredients are almost the same as the two gal VW/Audi jugs except it claims to be "phosphate and silicate free".
The deal is G12+ is supposed to be an HOAT, while the G12 is just a plain OAT. I thought I was sure and clear, but it just got more confusing. This "evidence" is only coloristic, not chemical. The ingredients list does say "corrosion inhibitors, defoamer, and dyes", so that could cover a lot of stuff and in fact allow the G12 and G12+ to be very different. It's just now a bit muddled inside my head.
Ingredient list from the G 012 A8FA4 stuff: ethylene glycol (107-21-1), diethylene glycol (111-46-6), sebacic acid (111-20-6), sodium hydroxide (1310-73-2), water (7732-18-5), corrosion inhibitors, defoamer, and dyes. the ZVW 237 G12 has the identical ingredient list.
Pentosin G001200 ingredient list: identical to the above up to the "water" component. That is the last ingredient listed on the Pentosin. The Pentosin says Phosphate and Silicate Free, while the two VAG products do not say this.
My questions now are: is the Pentosin an HOAT or just an OAT? Is the G 012 A8F stuff really an HOAT? If there is a difference between the G12 and G12+, it has to lie in the "corrsion inhibitors" part of the ingredients list. I am not doubting anything just yet, but I would like a further clarification based on chemistry. My brain hurts and I'm tired. This is my contribution for now...

As long as you're out of warranty, it's all good.
Otherwise the service manager will find all sorts of ways to explain why your tranny failed due to the yellow coolant in the tank. :-P
