I heard pennzoil causes sludge a couple of times.
Looks like a good one for the Castrol commercials.
Couple bogus slams on Pennz & QS.
Too bad we don't know the actual brand oil used and the OCIs. My guess is the owner didn't know either....

Unbelievable Internet "Expert" statements throughout.
This 94K mile engine is the famous Chrysler 2.7 V6 sludger - the same one I have. Except mine has 200K miles and looks pretty clean inside.
The 2.7 will create that kind of sludge with most regular motor oils when : OCIs are longer than 3K miles, and/or when the engine sees mostly stop and go driving, or mostly short trips. It will do the same thing when the OCI is stretched out even if it sees mostly highway miles, especially in a hot climate. The engine also had a significant modification to the PCV system in 2001. Engines prior to 2001 that did not get the PCV modification will tend to sludge.
