@Mark_ I won't bore you or anyone else with the why, but I'm a huge Mobil oil fan... They do have a MS-6395 spec oil but it's their Super Synthetic, not what is usually found in an O-Reilly's.

For others, and if you are curious, I wrote about more here -> http://sevenslotsyndicate.com/blog/k...ne-oil-change/ My comments on this spec and oil are at the bottom but are notated in the article.

There is four types of oil I can easily buy in my area, do you have any experience or advice?

- NULON 5W20 FULL SYNTHETIC FUEL CONSERVING ENGINE OIL
- MOBIL 1 FULL SYNTHETIC 5W20
- PENRITE ENIVRO PLUS ENIGINE OIL 5W20
- PENRITE ENIVRO PLUS ENIGINE OIL 0W20
All oil used must meet the MS6395 Chrysler standard.
Mobil 1 is not MS6395 certified the last I heard.
If it does not state on the back label Chrysler MS6395 certified then you should not use it.
Does it mean that for example Mobil 1 is not a good oil? Not at all but it does mean it does not meet Chryslers standard for oil in this particular engine.

I think a lot of people get wrapped up about this spec... It's just a testing and certification standard. It's not even that stringent of one to meet. In fact, it's a very old standard. Many oils are not listed to meet it only because they didn't pay to have that particular oil tested, instead, they decided to have it certified to a more up to date and tougher standard testing.

As I said though, Mobil Super Synthetic 5W-20 is MS-6395 certified.

I'll read the link from @SS_Syndicate a little later (I will), a bit pressed for time right now.

I've written here many times that Mobil has one or two MS-6395 specced oil (one is Super Synthetic and the other is one of their conventional oils), but not Mobil One. We can sit here and argue all day about how Mobil One is probably better for our engines than most MS-6395s out there, it doesn't change the fact that FCA wrote it down and we are *stuck* with it. Are most of us ready and capable of taking Exxon Mobil to court if our engine fails and FCA says we didn't have the right oil ? It probably would never happen in real life, but why chance it... My manual says MS-6395, I won't argue.
Mobil had a nice partnership with Chrysler before Sergio came in with his Shell buddies, so there's politics and egos involved now... and I want no part of that fight. And I'm pretty sure non Mobil One oil will allow my 3.2 to survive the 100.000 miles I may get from it...

@Mark_ I'm not disagreeing with you at all... If someone is concerned they should by all means use a MS6395 certified oil.

I personally rely on the fact the oil I use meets a more stringent certification and am exercising the "or exceeds" clause on the oil requirement. I certainly don't fault others who are uncomfortable with this though.

It's way to off topic to really get into here, but I had some issues with another Jeep using WAY too much oil when I started to use a Pennzoil MS-6395 oil instead of the Mobil-1. It also rattled like a diesel when cold. I opted to switch back to the Mobil-1 and the rattling was resolved. (It took more to fix the usage, but like I said,... another time.)

Interesting article......
"Jeep recommends oil that meets or exceeds MS-6395. This is an old and outdated specification and it can be tricky to find oil with it. The type of oil we are using in this write up has NOT been tested for MS-6395. It does however meet or exceed the required specifications. If you are concerned about warranty ramifications, Mobil Super Synthetic does have MS-6395 approval but was not available for us locally. It also is vastly more expensive."

Actually, Chrysler/Jeep only recommends MS6395 certified oil that meets Chrysler's standards. They do not say "recommends" oil that meets or exceeds". The key words are "has not been tested" which is part of the requirements for MS approval process.
Actually the claim of it being an "outdated specification and it can be tricky to find oil with it", is not completely accurate. I have had no issues finding oil in the 5/20 MS requirement.Not all oil has it but common oil like Pennzoil or Valvoline have the MS standardin the 5/20that my Cherokee uses. In fact a different weight of oil in those brands may not have the MS 6395 certification.
Also I do not understand "outdated specification". Basically I read that entire statement as justification to use their oil regardless of the lack of Chrysler's MS6395.

But to be clear,
There is absolutely nothing wrong with Mobil 1 oil and I believe it will do nothing to impact your warranty or the engine by using it but there is that small issue of MS6395 not being certified for Mobil 1.
There is also a difference in word semantics in the manual. That is "recommends only" vs saying "requires" MS 6395 is a big difference when it comes to warranty issues in my opinion.
But in the real world with available oil brands that do have the MS6395 certification I see no reason to vary off to the ones that do not carry that certification. Pennzoil full synthetic, which I consider a high quality oil, which I do use carries the MS6395 on the label.
I would just suggest that Mobil 1 get on the stick and certify their oil for us instead of minimizing the semantics in their statement. It is either MS6395 certified or not. If its not on the label then its not certified, regardless of what they are trying to say.

For the record, I never referenced what the "manual" said. I stated what "Jeep" recommends. I have contacts within Jeep where I discussed this. I also have (in writing) from my dealer that they do not use MS-6395 certified oil but rather an oil that exceeds its rating.

I'm happy you can find the oil locally, but I can't. So I stand behind my statement along with it being outdated (I consider a document 15 years old outdated).

The article was to help people change their oil, there is no reason to get butt-hurt about my views. Take it or leave it... Frankly I don'y give a crap.

Edit to add, and since semantics seem to be an issue. Here is an excerpt from the manual. Note: It doesn't say it has to me certified for MS-6395, but rather the manufacturer "only recommends" engine oils that "meet the requirements" of it and are API certified. A recommendation isn't a requirement....

The manual does go on to say that only oils of the proper SAE viscosity grade and API seal should be used. The API seal is not for MS-6395 though.

My dealer changes oil for the life of the vehicle free of charge. They have no admonition or hesitation using the Mobil 1, I bring in. In fact many of the guys in the service department with Jeeps, Dodge muscle cars and big Ram trucks also use Mobil 1.

Mobil 1 has been a standard for quite awhile and everybody has finally caught up. Not everybody, but Mobil 1 is excellent oil.

My wife's cousin who works for GM and went to GMI, with fellow grads also working for FCA and Ford all use Mobil 1. It's just been around longer before they started changing oil certifications and such.

If you want to get a very picky brand then go to Honda. They have so many proprietary fluids that it will make your head spin. Motorcycle companies spent so much researching lubricants. Mobil 1, just happened to pioneer the fully synthetic movement and used to be so much more expensive that the rest of most commercially available oil. Now almost all are priced competitively with one another.

I seriously doubt you can go wrong using Mobil 1 5W-20.

Again my $0.02. If you disagree, take it with a grain of salt.

Back to the OP. Get the 10W-30 changed as soon as physically possible.

Thank you all of your help.

Yesterday I got a call from FCA and they told me that the 10W30 must be a typo on the invoice but just to be on the safe side they immediately tow my car to a service and flush the oil.
They was very helpful I didn't even minded not having my car for the weekend.

So everything looked fine then I got home and just out of curiosity checked the previous invoices.
The previous 4 logbook service was made by Peter Stevens Motorworld in Ballarat and the used oil was the same Shell Helix 10w30 three times and once 10w40.

So I think now I rather need legal advice then mechanical
