Fiat, approves 5w30 in their Pentastar 3.6

http://starparts.chrysler.com/Fluids/2013LC_Fluids.xml

There has been a lot of conversation regarding, as to why Chrysler/Jeep changed the engine oil viscosity from 5w30 for the 2012, to 5w20 for the 2013,2014 Wrangler, on this Forum, and others.
Many, including myself have said this is CAFE caused. Others have said, no, it will cause damage to the VVT system, so don't do it, plus the factory does not recommend it.

Up to current, we have never been able to come up with something tangible, other than opinions, and word of mouth.

Well that has all changed now, because we have the proof, that 5w30 maybe be used as a alternate, if 5w20 is not available.

This originated from Fiat 9.55535-S1

So just click on the above Link, and read what Fiat has to say.....

I'm not sure as to why you can't open it? I just clicked on it and it opened right up.

I did answer you down on the General JK section.

Just do a Google Search for Fiat 9.55535-S1 and you will see it.

I will bring the link up again, to see if it works for you.

Just go down and do a Google Search for Fiat 9.55535-S1 and you will see the spreadsheet from Fiat, approving the 5w30 oil!

I sent you a pm, found the link and tried to post it to the pm. Not sure if you got it. Originated from a November thread called " 3.6L woke up".

The 5w30 argument didn't work out in other threads so you decided to start your own thread to pimp out this misinformation.

I guess if you search long & hard enough, you'll always find at least one article on the internet to support a point of view, not matter how much sense is made to the contrary.

I am not going to try to degrade your comments, as you have mine.
Because it serves no purpose. You have a opinion, and I have a opinion, so what's the big deal.....
This is just part of being on a Forum! Not everybody is going to agree with you, or me all of the time, so what!!!!

I'm really sorry that you view differences of opinions, as a argument...
I would rather view them as a opportunity to share a different prospective on a subject, and learn from one another.
So what ever makes you happy, then go for it........

So in closing, can we at least agree, to disagree???

The oil viscosity was changed in 2013, along with a new design oil pump. This may, and this is only a guess, be a design change to help flood the top of the cylinder head with oil. This would aid in carrying heat away, and would be part of the fix for the 2012 head problems. I'd seriously reconsider changing the viscosity away from the recommended 5w20.

I don't see anything that is actually recommending 5-30 in my 14 3.6L and not sure why I would run it when my owners manual clearly states 5-20 and I have 100,000 mile warranty on the engine. Running 5-30 won't make me feel any more warm and fuzzy then 5-20. Now if I were in the middle of no where and someone drained my oil then I would run whatever I could get lol.

This is in the 2013 owners manual ... what other official document is needed to topple your ego?

what page as my 2013 says 5-20 and I for the life of me can not find where it recommends any other grade. Not saying it aint so but mine is over 651 pages so could have missed it. on 611 in the fluids and genuine parts it says 5w-20,page 568 it says the same and says oils without the correct sae viscosity number should not be used.

The new owners manual does say you can run 5w-30. It's the Fiat spec mentioned above. You can download the updated owners manual from Jeep's website.

That being said, the only oil that I found meeting the material standard appears to be
Pennzoil Ultra Euro L 5W-30.
The same stuff Ferrari uses, about $10 a quart.

It's not a recommendation... an approved alternative. Please note the reason for the change.

I live part of the year in Phoenix Arizona with temperatures as high as 122 degrees, and asphalt radiation measured at 165 degrees.
The other time I spend in Fairbanks Alaska, of which I have seen temperatures of -47 degrees, with a wind chill of -80 below.
So my oil of choice is Castro Edge full synthetic 0w30. I use this in all four of my vehicles, including my 2013 wrangler. My Wrangler currently has about 18,000 miles on it. This oil performs very well in all four of my vehicles, at these extreme temperatures. I use my wrangler more in Alaska, because of the snowy road conditions.
I base my oil type and viscosity on temperature range, rather then type of engine, being pushrod, or VVT.
I highly recommend 0w30 Castro Edge synthetic oil for engine longevity.

IIRC CAFE states they must show the oil that was used to achieve the advertised mpg, and the oil used for CAFE credits. I like the idea that they now show two oils in the owners manual instead of just one grade like some of the older Jeeps do. It cuts down on the oil wars on the message boards. Bottom line is a 30 grade oil, and a synthetic oil is not going to grenade a 3.6L Pentastar engine. There is also nothing wrong with using a 20 grade oil in the winter and a 30 grade oil for the summer depending on where you reside. Just be sure the oil meets the Chrysler specifications and you're fine.

I agree with demarpaint but for those more interested in protecting their engine than in Chrysler warranties or complying with Federal regulations there is another perspective.

I can certainly see the application for higher viscosity oils in high temp regions and the practice of using a different viscosity oils for different seasons made sense. But multi-grade oils introduce another variable: shearing of the additives that provide variable viscosity ( Viscosity Index Improvers) in some engines. Over a relatively short period a 5w30 can effectively becomes a 5w20 in some engines.

Effects of Shearing

If Bob is not a credible enough authority on the subject, there are plenty of SAE papers on the subject.

This is starting to sound like an argument about removing the "DO NO REMOVE" tags on mattresses.

^This shearing is correct for Conventional oil. Many will shear down from 5w30 to 5w20 in about 1000 miles.
This does not apply to synthetics, because they are very stable! This is also, per Bob the oil guy!

So, if I can use 5W30 in a pinch, can I extend my oil change to 3500 miles from my normal 3000 miles that Jiffy-Lube recommends?




The above is a tounge-in-cheek comment. I'm still going against most of the advice on this forum and letting my EVIC tell me when to change my oil. It has alerted me right at the 9,500 mile mark for 3 times so far. I'm waiting for the next message to come around 38,000 or so. I'll probably stick with Mobil1 just because it's not approved and I want to see how far I can go before she blows!
