Oil Change - What lube, and should I have Jeep do it?

[mazeppa]

Castrol Edge is reported to meet Chrysler Spec’s.

https://www.amazon.com/Castrol-03124-0W-20-Advanced-Synthetic/dp/B00JGQLZJ4

According to Castrol web site 5w20 and 5w30 do, but 0w20 does not.

See at the bottom of the page: "AVAILABLE IN THE FOLLOWING GRADES:" and select grade.

Not sure if I will be using a 0w20 oil after first oil change.

Considering the head issues the 3.6L continues to have, I don't think I would experiment with the oil weight or specification.

None of the Pentstar head issues have ever been attributed to incorrect oil spec or weight used. All have been material defect and/or assembly quality issues.

All I am saying is that it is an engine that has a history of issues and all this back and forth about what oils can be used and not be used sounds more like a couple kids not doing what their mother told them to because the only reason given was "Because I said so." There are plenty of oils that meet the spec that people who are much more qualified than any of us have agreed upon so there is no real reason to rock the boat and risk causing more issues with an engine that could still have some kinks to work out. There will always be people who think they know better, but I urge people to just follow the recommendations given in the manual and on the engine fill cap. As we have seen with the steering play and other issues, FCA will try and deny problems and given a loophole to jump through would love to put a couple thousand dollars of warranty claims off on the owner because they used the wrong oil. Maybe it won't hurt anything, maybe it will. With the number of 3.6L engines I see in the shop with problems every week, I think I would play it safe and just put the right oil in it. Maybe this is just rubbing me the wrong way, but it all seems like a childish way to act when I doubt anyone here is really qualified to argue the point of oils specs for the 3.6L engine.

How does the dealer know what weight oil is in the engine? They only check for oil, and if the level is too high or too low. If it's really an issue for warranty denial, one would just change the oil before taking it to the dealer.

It's not childish behavior, it's a concern for the longevity of the engine. If I still lived up north, I would not be concerned about it. Where I'm in a hot climate, the switch to a thinner oil is a concern for me, especially since the primary reason seems to be for overall better fuel economy. By the time I have used my four Jeep Wave oil changes, there should be additional information available to make a better decision.

If there is a warranty issue, the dealer can do an oil analysis and determine what oil was used in the engine. I don't know what "better information" you would need, the people who designed and built the Jeep have already told you what it requires.

No, they told me what they recommend be used. The word 'required' is not in the owners manual. The Pentastar V6 has been around for quite a while. What they say should be used in the engine has changed several times over the life of the engine, with no known significant changes to the engine or any explanation for the change in recommendation (other than fuel economy and easier cold weather starting). Others have reported that they are using, or going to use, different oil than what it recommended. I'm waiting to see what their results are while I use up my free Jeep Wave oil changes. I might even move back to a colder climate during that time, in which case it would no longer be a concern for me.

I would disagree that there have been no significant changes in the 3.6L. The changes in the heads are just a couple changes I would consider to be significant.

I have always used the reccomended oil spec but typically mix 2 -3 brands....my first oil change had 1 mopar, 2 royal purple and 2 mobil 1

I changed all my oils except the ZF 850re transmission at 1000kms. I pulled a sample and took it to the lab for my proof I did my own changes. Lab result came back on the engine oil to say there is a “trace engine coolant in the oil”. I have 4000kms to go for the next oil change and will see if there is coolant in that sample. In my case, I’m glad I changed it early and I have the lab results they can’t argue. I use Amsoil. I will also be swapping out the ZF Life Guard 8, (“life time” marketed crap SEMI SYNTHETIC mopar oil) from the transmission next month to Amsoil Signature 100% synthetic ATF and again will have the lab results to prove what came out.

Do what you want but I wouldn’t mess with the transmission oil, these are pretty complicated transmissions and don’t require frequent service.

I agree and I certainly would not use any fluid that is not expressly approved by Jeep if you think you may have an issue...

No issues yet but I’m also not wanting any down the road so just upgrading the oil. Got the approval from Amsoil that the Signature ATF is approved for this tranny. Also, when ordering the pan/filter/gasket from Mopar, the parts guy ask why on earth would I want to change the oil over with so few kms??

I started reading him the data numbers of his ZF Life Guard 8 oil and Amsoil’s data numbers and half way through the data he says “STOP, I get it, you’re good!”
Here’s the data sheet.

Is Amway going to replace your tranny or pay for repairs if there is a fluid related problem? I don’t see what their approval matters.

Amsoil stands behind their customers and their product. I can guarantee that if their oil was not compatible with the transmission or for any other oiled application they would tell you and it would be stated and documented.
