Only if you define "synthetic" as "from Group III base stock", which many (including the Germans) don't - regarding instead Group IV (e.g Royal Purple) and Group V (e.g Redline) non-hydrocracked base as "synthetic".

From a 2010 post on a leaked Exxon Mobil powerpoint presentation regarding Mobil 1 using Group III - and Viscom *Mobil 1 - PAO & Visom - Bob Is The Oil Guy:

I reported this change in the M1 formulations here four years ago and a global firestorm ensued. I took lots of grief over it, including people writing to the owner of my company, and dragging my name through the mud on the Internet. There are still people who adamantly deny that M1 formulations use Group III.

This presentation, dating sometime between 2005 and 2009, clearly shows that EM changed the M1 formulations to include Group III+, and that they did not want to tell their customers:

With the exception of Germany, this reformulation will be invisible to consumers and B2B customers.

There will be no proactive customer communication relating to this reformulation. However, an internal briefing document and Q&A has been prepared to allow sales to respond in the unlikely event of a customer question.
This explains all the canned responses customers got when they asked EM about the change.

As I have consistently said, I use M1 and consider it a great oil, but I am happy that the truth is finally confirmed by EM. My name is finally cleared.

It would be illegal to describe Group III oils as synthetic in Germany, BTW. Which is presumably why the change isn't "transparent" there.

The debate rages on in that thread for some 30 pages.
