My thoughts are that a full synthetic has a higher flash point than any dino oil so it will be alot less likely to turn to carbon or coke in the extreme heat of the turbo housing.
Partial synthetic means absolutely nothing... it's 100% marketing because they could put one drop of synthetic in a quart of dino oil and call it partial synthetic and what is that supposed to do? BFD.
Even if it was 50% synthetic, the other 50% of dino oil can still turn to coke or carbon...

I'm not a scientist though, but I have had clogged cam spray bars ($$$ ouch>cams and rockers) from carbonized oil particles origonating from the turbo housing so I will only use full synthetic oil.

Because of that you couldn't pay me to use Brad Penn or any dino oil in a 930.
...and I do let it idle for a while after driving it to cool off the turbo housing.
