In my **opinion** Bill, yes. One of the most desirable 
characteristics of synthetic oil in a TURBO car is its ability to 
resist coking/burning onto turbo bearings *which are usually just a 
bushing, not even a bearing.  If synthetic did not prevent such a 
failure, it almost certainly would considerably extend the service 
life of the turbo before it would fail.

That's my **opinion**, and I'm stickin' to it.
