OK here's the response from Andrea Forni - yes he replied, wow!
Mr. Bannister, good afternoon.
Sorry for the delay in this answer.
I guess you are referring to my interview appeared on “ashonbikes”, that I report here :
There seems to have been an unusual number of cylinder head failures, can you tell us anything about this?
"Yes, there have been some problems with coolant escaping into the lubricating oil. This was caused by an unexpected internal corrosion problem caused by glycol-based anti-freeze. We have changed the anti-freeze specification to a non-glycol one and this has cured the problem. We now recommend a non-glycol anti-freeze for all existing Testastretta engines."
If so, I would like to clarify some statements that could be misinterpreted.
The above interview was related to Multistrada 1200.
Is a matter of fact that we faced a few cases of cylinder head corrosion on Multistradas. but other Ducati models (1198, Diavel, Streetfighter) are not interested.
Too long to detail why, but this is what actually happened.
It’s also true that the change of original anti-freeze to one with better anti-corrosion properties cured the problem (on the affected bikes, therefore on Multistradas).
It’ undeniable that new anti-freeze has better anti-corrosion performances than older one.
Therefore, on assembly line, we shifted to the new one, and, for obvious standardization reasons, the new anti-freeze is now applied to all liquid cooled engines.
But your Diavel (as well as 1198, 848, Streetfighter, ecc.) does not need the replacement of anti-freeze before the expected normal service interval.
Of course, when you will perform the next scheduled service, we recommend you to use new one, but you are not required to do it as a sort of urgent action to prevent damages.
Finally, please let me clarify that the differences between old and new anti-freeze are basically the additives of the products, and not the base component that is still glycol.
The wrong statement was due to a my mistake in the interview, I apologize.
Hoping that I have clarified your doubts, please accept my best regards.
