NOT THE RIGHT OIL.
That is primarily a GAS rated oil, that is the "european car formula" and is only rated CF for diesel which is the absolute minimum rating the CRD should ever have, and certainly not for extended drains. When the CRD was released, the CF standard had already been superseded several times and the current standard at that time was CH. The CF standard dates back to the mid 1990s.
The following are all acceptable options, and can be switched at will based on cost or preference within this list:
Mobil 1 Turbo Diesel Truck 5W-40
Mobil 1 Delvac 1 (Silver bottle) 5W-40
Mobil 1 Delvac ESP (Silver bottle) 5W-40
Mobil 1 Delvac 1300 (black bottle) IS NOT ACCEPTABLE as it is not synthetic.
Shell Rotella T6 (blue bottle) 5W-40
Chevron Delo 400 - IF CH or higher rated and fully synthetic 5W-40 - information on this one is varied.
The oil specified by the manufacturer is not the right oil? I probably shouldn't be surprised given Chrysler's general approach to this car, but I'm not sure why I would assume that. Especially considering I've sent about 20 samples to Blackstone, which is an oil specialist, and never once have they written back that this is not an adequate oil for this usage. I'll switch but it's kind of closing the barn door after the horse is out ... or would a couple of shorter runs with one of the above oils be enough?
Exactly. Its because its Chrysler. They did the same thing with the Ram Ecodiesel. After a bunch of them blew up due to bearing failures they started recommending 5W-40(I think rotella T6 maybe)
Regarding ram EcoDiesel, there is no proof that the factory recommended then pennzoil euro L 5w30 (which is actually a diesel rated oil compared to Mobil 1 0w40 which is a gasoline oil also diesel cf rated) has any connection with bearing failures. It has to do with the corporate deals. On the contrary, there were few folks that posted quite disturbing facts and tests with Rotella T6, related to excessive foaming and engine failure (not EcoDiesel). My own take is that both euro L and t6 are great diesel oils. I use both of them and oil analysis is equally good. T6 with deal price is unbeatable.
Regarding 0W-40 mobil 1, I used it and no issue, but I also have gde Eco tune. I had a bunchof it on stock. Now I use Rotella t6 since is the cheapest good oil.
To the op: definitely changing the oil won't hurt. If you have a bunch of 0W-40 on stock, do an oil change with it, drive 1,000 miles to clean the engine and do another oil change with t6 or mobil 1 tdt, and get a sample at 2,000. Based on that sample, you'll know how much can you go with the oil change.
Oh, and quite important, I'm not sure how you take the sample, but you should let a bit of oil to drain before taking the it, to make sure you don't sample the bottom of the oil that sits on the pan.
