"Complaint oriented webpages". Wouldn't a lot of complaints point to a problem?quote:

Chrysler has issues with sludge. The 4.7 included.

These types of links(last one deals with the 2.7 of which 650 of 750,000 engine
have a known/documented sludge issue) are useless complaint oriented webpages which I could dig up on just about any make or model if I looked on the internet.
Here are some links to the 4.7, do a little reading about it, last link shows 4.7 during HO cam install, looks clean to me

This is way overboard and will do nothing for you. If you want to do a couple short OCI I'd use dino, synthetic isn't going to clean it out any better IMO. Switching to a 1000 mile OCI permentatenty is definately uneeded.quote:

As for the whole Chrysler thing - I didn't say the whole engine line is trash - Chrysler has had design issue...engines, transmissions, ball joints...but so has Toyota, GM.....sheesh.quote:
....follow the AutoRx advise. Do a two or even three cycle clean and rinse.
I don't think any synthetic oil will clean well enough or in time to prevent further damage. Sure synthetic oil does some cleaning - but oil is for lubricating, not cleaning sludge bombs. My apologies even to the fellow HDEO heads
Actually I am the one that assumed it was a 4.7 and started alot of this - so blame me for that.quote:

VNT, i started fighting with the 5.2 and 4.7L topic a few months ago.... don't even start. They are all set in thinking that those consumer reporting websites are 100% genuine sources. There are people on that site that don't even know the displacement of their engine. Some of those people think they have the 4.7L in a 2000 and some think they have a 5.2L in a 2001. The 5.9L was also an option in the Durango... I think it's just consumer negligence because there are people on JeepsUnlimited that don't have these problems AT ALL. If they did, 47,052 members of JeepsUnlimited would know about these problems.
FYI, THIS DURANGO DOESN'T HAVE THE 4.7L V8!! IT WASN'T AN OPTION UNTIL 2001!!!!
Once again, our 2.0L with 5 quarts, and a higher efficiency design ought have less waste heat to the oil, and ought to have MORE of these problems. It does not, despite MANYquote:

Totally agree with the first part. She drives a mile to and from work and changes the oil every 5-7K. There's your problem. I don't think Castrol or the engine design have anything to do with it.quote:

Castrol is NOT AT FAULT HERE.
When you put "ought" in any statement, especially 2 or more, then there is no fact to base anything on.quote:

This is a USER issue. Negligence, lack of longer drives, lack of oil changes, driving it too hard while cold, etc., etc.
