Mobil 1 and Chrysler

I've been following some of the discussions in various threads regarding the fact that Mobil1 oil no longer meets Chrysler's MC-6395 specifications, and most of the threads state that the reason is a "political" issue. I don't know the most minute details and don't really care; I DO care, however, that I can no longer use my favorite oil in my JKU without big daddy's permission! That said, I did want to find out more info instead of just reading opinions and rumors, so I did a search on the Mobil1 website for some Q&A directly from them, in the hopes of getting their side of the story. Simple as it is, here's what I found:

Question:
Mobil 1 5W-20 and Chrysler MS-6395
Why is your Mobil 1 5W-20 not Chrysler MS-6395 spec approved? Or if it is, why is the certification not on the bottle or website?
-- Josh Eads, Cabot, AR

Answer:
Chrysler’s latest revision to the MS-6395 specification calls for a field trial spanning multiple seasons over two years. While we fully expect the exceptional performance of Mobil 1 synthetic motor oil to meet Chrysler’s specification requirements, at this time we are in the process of evaluating our timeline to start this testing.

Sounds to me like it's all about the timeline, and perhaps one that hasn't begun yet (don't know the date of that Q&A). Hopefully it gets resolved quickly, but two years? At least? Ouch!

Meanwhile, has anyone else noticed that *ONLY* Ford's specs are now listed on quarts of Mobil1? Really? Is that the ONLY auto maker who authorizes the use of Mobil1? Amazing.

EDIT: The date of that Q & A is 2/15/12. Wow...looks like at least two more years to go then, based on Chrysler's requirement.

Read the label closer, as honda/audi are also approved with mobil 1. If your happy with mobils answer, great. There is no reason it shouldnt be approved, but the bottom line is that it isnt.

Mobil 1 is approved for GM "Dexos" oil specs. I just did my first oil change on my 2012 Wranger recently and used Quaker State Ultimated Durability 5-30 (full synthetic) but I didn't really check to see if it listed a Chrysler spec on the bottle. I guess I should double check it because I could see Chrysler blaming a cylinder head failure on use of the wrong oil. I don't want to jeapardize the warranty because I've got a feeling I'm going to need it based on the number of heads being replaced.

I always use Purolator filters because they are inexpensive and incorporate an anti drain back valve.

Hmmm I had a 2006 SRT-8 Dodge Magnum that had mobil 1 0w30 in it from the Chrysler factory. Delearship oil changes until 2010 were done with Mobil 1. It is difficult to believe that suddenly it is no good for Chrysler's engines.

So race cars and motorcycles can use it but not Chryler engines? It is definately poltical. I would hire a lawyer in an instant if my dealership denied a warranty claim because I used Mobil 1. Heck when I toured the dealership service department they were still using mobil1 and this was in May 2012.

As I recall, conventional Mobile 1 did meet Chrysler spec But the full synthetic (the one I wanted to use) did not.

Well this sucks, I had planned on using the Mobil 1 synthetic 5W-30 for my next oil change. Now I don't know what to use lol. It was recommended so much around the other oil threads I don't remember what else was good. I just remember something about the royal purple stuff not being anywhere near as good as it was claimed to be. So what about penzoil or valvoline?

Interesting. At my last oil change (beginning of May) at a Chrysler/Dodge/Jeep dealership, I requested full synthetic, and asked for Mobil 1. They said sure.

Of course I have no real way of knowing that's what they put in, but that's what is on my receipt and service record.

There are several oil threads on WF. Even a labratory study on oils lubricity and break down efficientcys. As I recall Including Mobil 1, all major synthetics exceeded the toughest of industry standards. Boiled down to Brand preference as they all were outstanding.

I believe that on the new SRT's Pennzoil Ultra is the recommended oil. No one has been able to explain to me when I asked why they switched on the SRT's to the now recommended Pennzoil. Maybe Bob the Oil Guy forum has the answer I have not looked there yet.

Correct! I was referring to full synthetic in my post. Forgot to mention that.

I'm definitely not happy with the decision, because M1 is my favorite oil, but the answer isn't the decision. It just explains why the decision was made...because of Chrysler's demand for two year testing in multiple seasons, and we consumers don't really have a choice in the matter unless we want to risk warranty coverage issues.

And the synthetic quart I looked at yesterday did not list ANY other automaker specs except Ford. Honda/Audi were not listed, nor were others, so either you were looking at an old quart or I was...courtesy of O'Reilly's. Not disputing what you saw -- just saying what I saw, and I did look closely. Even the old dude behind the counter mentioned how odd that was for such a quality oil to list only one spec. The old quarts I have in the garage, on the other hand, list four -- GM, Chrysler, Ford, and Honda/Acura (not Audi). In any case, weird stuff...and I ain't happy.

I don't get what the big deal is. Use the oil you want and get over it. So Chrysler and Mobil had a fight...there is NO way Chrysler can deny warranty claims based on using M1. What if i take my jeep to the local mechanic to get an oil change and tell them i want synthetic and it happens to be the brand they use but don't disclose it to me. Is Chrysler going to deny me warranty work because for 3 years I've been having Joes Garage change my oil and he used M1...i think not. my .02

The sad this is, even though it is probably just a testing issue and it exceeds the requirements in the long run, but since it doesn't meet the requirement at this time and if something knock on wood would go wrong in the meantime, some dealers could void the warranty on the engine if something fails and they want to blame it on the oil. Whether Mobile One would cover it at this point is another issue. Not saying anything bad about the oil just how some less then stellar dealers work.

One option to consider might be Castrol EDGE with SYNTEC Power Technology (formerly known as Castrol Syntec...full synthetic). According to Castrol's website, Castrol EDGE 5W20, 5W30, and 10W30 all *do* meet Chrysler's MS-6395 spec. I know their Syntec Blend brand also does, if you'd prefer not to go full synthetic. From my own personal perspective, I used to use Castrol's conventional oils exclusively in my cars before finally switching over to Mobil1 (because at the time Castrol didn't offer full synthetic), and now that Mobil1 does not meet MS6395, I will probably go back to Castrol and use Edge.

2012 owners manual page 519 says the manufactuer reccommends only API certified oils and the last time i checked mobile 1 is API certified. If its good enough for my corvette which clearly states on the oil filer cap to use mobil 1, then its good enough for my jeep.

There are several oils as good or better than Mobil 1. Use one of those till Mobil 1 meets the spec. It will take some time, evidently.

"API certified" is a certification, not a specification. Just because an oil is API certified doesn't mean it meets Chrysler's MS-6395 spec...and Mobil1 does NOT meet it anymore. It's good enough for my Mustang and F-150 too, but to Chrysler, suddenly it's NOT good enough for their vehicles...and I hate it! Unfortunately, it is what it is, so use it at your own risk. If Chrysler ever questions your oil choice in the event of a breakdown and your warranty coverage, I sincerely hope your decision is supported and works out for you.

Look, Mobil1 is my favorite oil and I WANT and PREFER to use it in my JKU, so in no way am I trying to steer people away from it. My only goal in starting this thread was to put the info out that I found directly on Mobil1's website...their version of the reason why the MS-6395 is no longer listed on the back of their synthetic oil quarts. Countless people, including me, like Mobil1 and WANT to continue using it. Unfortunately, Chrysler says otherwise.

I did....cover to cover....and i recommend you do the same. Page 521 in particular states "...manufacturer recommends engine oils that are API certified AND AND AND meet the requirements of Chrysler Material Standard 6395."

Choosing an oil just because it is merely API certified (as virtually all major brands are), and without regard to the Chrysler specification (see the word "specific" in that?) could be a grave mistake on your part. Again, API certified is NOT Chrysler's specification or only requirement.

Dead horse.

I'm using Mobil 1. Period.

Let the dealer/Chrysler try to deny a warranty claim based solely on Mobil 1 not being specifically approved by Chrysler. I love a good fight when I know I will win in the end. (see Magnuson-Moss Warranty Act)

It'd also be interesting to see Mobil sue Chrysler for defamation!

And, they will only know you used Mobil 1 if you tell them.....

Chrysler always "recommends" OEM or "approved" parts and maintenance items. That recommendation is just that, a recommendation, it is not a REQUIREMENT to maintain your warranty....

I completely agree...100%. I'm very hesitant to switch to anything other than M1, but I'm also very hesitant to have a fight on my hands with Chrysler in a "what if" warranty scenario. They gave me two years of free oil changes and I've only let them change it once so far, so they can put in whatever they want in it until I do finally decide to cut the ties and do them on my own (probably after 2nd change @ 5-6k miles). But when I do, I'd really like to feed the JKU some high quality synthetic and don't feel like getting grief about it from Chrysler. Laws may back us all, but is the fight worth the aggravation that comes with it? Nothing worse than arguments with dealers and automakers.

Why are you hesitant to try any other national synthetic brand? There equally as good, some also cheaper to but.

You see the magic word is reccomends, no where in the manual does it state not to use Mobil 1 nor does it give any explanations of Chryslers specification other than standard 6395 (with no explanation of that) and to use API certified and to use 5w30 oil. However , not to change the subject but the manual does state not to use Armorall products with no explanation about that either. I don't know if i will use Mobil 1 or not since i only have 1700 miles on the JK right now and its not time for an oil change. The reason i use it in the corvette is because the owners manual does clearly state to use it or its equivalent and it states Mobil 1 on the filler cap. Now the way i understand it from the corvette forum starting in 2012 GM now states in the manual to use their own oil whatever that is but the dealer changes the oil in the vette and they do put Mobil 1 in it since that is what is called for on the 2011. If you do not want to use it then do not use it but there is no way that a warranty would be denied because of using it.
