In either case if you believe your engine will go the distance then go for it. Just try to get the largest oil filter you can and see what happens. For the oil to still be clean and gloden color I'd might not consider changing it either. Still for my 4.7 I'm an ole [censored] and prefer to do mine every 3K.

Durango - It is not a diesel engine it is gas. He is asking about using the diesel 5w30 because it has stronger detergents.
CMB - dude. Relax a little. This isn't that big of a deal. I am not trying to be a jerk but are you ever going to pick an oil and just do it? You are worrying needlessly.
Pick an oil and go with it. There is not enough difference in them to make that big of a difference in your engine. Any synthetic will combat sludge better than a conventional oil. If you change the oil regularly you will be fine regardless of the type and brand of oil you use.
For synthetics Amsoil, Royal Purple, Mobil 1, Red Line, Quaker State, Valvoline, Castrol, Pennzoil, etc... all offer excellent oils. Pick one and just keep an eye on it. I wouldn't go 15K+ myself on an engine prone to sludge but you certainly are fine up to 10K with a good quality synthetic like Amsoil, RP, PP, etc... If it makes you nervous use something a bit cheaper( PP is pretty cheap )and change it at 5K-7500.
If you are uncomfortable with the cost of changing a synthetic at 5K-7500 then pick a quality conventional oil and do it every 3K.
You can keep asking the same thing 30 different ways but the answers are still going to be the same. Again, I mean absolutely NO offense by this. I am just trying to get you to chill a bit. You need to make a decision and get on with your life though. This is not that big of a deal
Just curious is this your 1st vehicle?
No, this is not my first vehicle, it is my seventh! This is however my first Chrysler, as well as my first used vehicle. It is also the first vehicle that I have ever owned that has major sludge issues! (documented all over the net) I am "chilled" but no one has answered the question. Amsoil is expensive, I don't have money to throw away changing expensive synthetic every 5k, which a lot of people are telling me to do. Since this is my first used vehicle, I don't know how it was previously cared for, so I want to take every precaution possible to not have a motor blown out from sludge. My question was, will amsoils diesel 5w30 be a better choice for a motor that I don't know the history of? Will it help fight off sludge on extended drain intervals better than the regular gas synthetic? Will it clean any existing sludge better than the gasoline synthetic? I don't think these questions are too unreasonable, and it people here don't know the answers, thats ok. Just say so, don't leave me hanging....
Sorry if I seemed upset, because that is really not the case, trust me. I am a member of many forums, so I know that when you don't know someone, there comments can be taken in different ways...
