GRAND TOTAL as of 04/23/2016
Engine Failures = 56
Oil Cooler Failures = 26

WOW...that's a lot of bad motors. And, while I know that these modern diesels require some diligence in maintaining them, they simply should NOT be failing at this rate.

Thanks for the info, Summit

Yes. Everyone should disregard the earlier comment suggesting that Mobil 1 oil products cannot be used in our engines. That is a false statement. As Rule62 pointed out, Mobil 1 ESP 5W30 has the requisite MS-11106 certification, thereby approving it for our engines (as opposed to regular Mobil 1 5W30).

More to the point, these low-ash oils we are *required* to use are actually *harder* on the engine. Many of the unapproved oils are probably better lubrication for the *engine* and would likely result in *longer* engine life on our EcoDiesels due to their inclusion of the industry standard organometallic lubricants. Those organometallic compounds will poison the DPF over time, though, which is why standard oils aren't approved for our vehicles.

Thank the EPA for shortening your engine life.

^Dang, could you know a little bit more about oil?!? why don't you guys just use Rotella T6 or something similar?

Haha, well it's not really in dispute that the organometallic compounds will ash a DPF nor is it disputed that the very same compounds are standard lubrication additives.

There are some on the forum who are running regular oil (i.e. not the approved low-ash) because they want superior engine protection more than long-term DPF survival. That's not an entirely insane perspective: these days you can buy a delete tune and then remove the DPF & SCR from your vehicle.

Motor Bricked at 19,600 miles..

Are superior engine protection and proper lubrication incompatible with DPF health? Isn't there some type of additive (approved or otherwise) which would allow us to have our proverbial cake and and not blow up our motors?

Re: Motor Bricked at 19,600 miles..

Google black stone results on Mobil1 ESP for those that have used it in Jeeps and Dodge Rams. You will be surprised how well it performs.

Re: Motor Bricked at 19,600 miles..

Hello to all.

Save you the search.

My latest Blackstone oil report for Mobil 1 ESP 5W-30. I had repurchased a pack of six oil reports, but as things are going so well, I haven't bothered getting anymore done. I'll continue with the Mobil 1 ESP as there really is no need to change or experiment.

Re: Motor Bricked at 19,600 miles..

So, based on this report and the fact that my crankcase had "plenty of oil" in it according the tech tearing down my motor, the quantity and quality of oil was not the problem.

It's going to sound crazy, and maybe even shitty, but there's a good chance there isn't anything you could have done differently.... Not every vehicle made is going to be perfect. They're going to see some sort of QA issue and make it right. It's crappy and inconvenient, but it just happens.

Re: Motor Bricked at 19,600 miles..

I understand that engines go bad. I went through this with Cadillac back in the 80's and again in the 00's. My issue is that we're pushing two weeks and I feel like there's no sense of urgency to get it resolved. The service writer suggested that 3 months was not out of the realm of possibility to get it back up and running. That is NOT going to work for me. And I've told FCA that my extended 1.2 million Twitter followers probably wouldn't be happy about it either.

Re: Motor Bricked at 19,600 miles..

Here is my question.
What are your expectations and have you communicated those to FCA? I think this will help resolve the speed and what gets done vs letting them call all the shots.
An engine self destructing is not unusual for a dealership to see but is unusual for an owner.
Maybe you have conveyed these to the dealership already privately but they have a responsibility to get this resolved. My dealership is pretty amazing some are some aren't so not sure how well they are treating you.

FYI regarding the oil analysis my Pennzoil ESP gives the same results as what was previously posted for Mobil 1. This means the oils they picked are terrific and protect the engine.

Nothing will protect a latent defect like a casting flaw in a crankshaft that will operate perfectly until it gives way. Something let go or the engine would be fine.

I would not be happy if this happened to me as I do enjoy driving my Jeep a great deal...

Re: Motor Bricked at 19,600 miles..

I would expect to have a new motor installed and warranted against manufacturing defect for life within 30 days of diagnosis.

Alternatively I would expect to be bought out of my current vehicle and put in an identical 2016 model for a very modest mileage offset with the same lifetime warranty.

I used to sell Cadillacs and while it wasn't unheard of to see a car come in with a bad motor it wasn't common either. And you can bet our customers weren't going to wait anything like 90 days to get it sorted out.

So there's your answer. And I have communicated this very directly...using common language...these expectations to both the dealer ( whom I don't think gives a rat's hairy ass) and to FCA, which so far hasn't been much more empathetic.
