It is a mix. If there is a precipitate, it would be G12 precipitating, since it contains some silicate while Dexcool does not. However, in cases where it does happen, it would be due to a mix of acid and alkaline chemistries causing a precipitate. In these cases, the old green coolants are alkaline and contain much higher levels of silicates than OAT based coolants.Again I'll ask: have you been running 100% Dexcool in any given VW engine, or adding it to engines already containing G12?...
And no, I never claimed some people have not experienced problems with Dexcool, just that you, nor anyone else, have not posted photos of it nor provided documentation of it happening in a recent VW application. You, OH, are just as bad as anyone else at jumping to conclusions without considering all the details of a given post.
What I say is this: in 10 years of mixing Dexcool at varying levels with G12, I have experienced no problems. Is it the 'wrong' coolant? Probably depends on what you are selling. If you are a VW dealer, then sure, it is absolutely wrong. If you are an aftermarket vendor, then it is poison. If you have some sort of identity crisis going on, then I cannot help you; please spend too much money for no gain.
There are a number of people for whom travelling to a VW dealer to buy overpriced coolant is a PITA. Buying online is adding the insult of shipping to the aforementioned injury. For these people, telling them that using Dexcool will destroy their engine is a lie. You have no proof. I have tried Dexcool in my engine without any problem. It works for me.
I do not brag about spending too much money for something. To me, it is similar to shopping and paying $3/lb for the same apples I could buy at the other store for $1/lb. Sure, it is a different name on the shopping bag, but the apples taste the same.
Here, the analogy isn't perfect, but analogies seldom are. Hopefully you can see my point. Just because the coolant does not have a VW logo on the container does not mean that it will not do an excellent job, in fact as good as anything that does have a VW logo on the container.
But, please believe what you will. I know I cannot change your mind. If it makes you feel better to be using the 'right' vs the 'wrong' coolant, then go for it. Whatever soothes the ruffled feathers of your ego is OK with me.
