Some think Ultra's reported Noack value is too good to be true given it evidently still uses a fair amount of Group III (super-refined conventional) base oil. On the other hand, these are the values Pennzoil has reported and confirmed.

I'm using Ultra in my Focus because of the low reported Noack. Even if the volatility numbers are wrong, it's still a great oil. Hard to see how one could go wrong.
