Anybody think it would be a good idea to switch to 5w20 in a 2012? Think this might to help the potential Tick?

I've always heard if switching from the oem spec oil most go heavier not lighter, but these were V8's?
Is there a site that list the TSB's & recalls for JK's?

I'm not sure about Chrysler but when I worked at the ford dealer there was a tsb that listed all the Vehicals ford recommended that you could switch from5w30 to the 5w20.

Yeah, Chrysler did something similar with the ATF +4 came out. They recommended it be used for all transmissions that spec'd for the +3, if memory serves.

Sharkey did the right thing - asking his Jeep question here - attacking him for asking it - not cool!


On topic. In a long thread on breaking in a new 3.6L that ran more than a year ago, a lot of us old timers, including an automotive engineer who worked on Pentastar development, agreed that a good routine is to change oil and filter early and often.

I changed oil and filter at:

500 miles with dino oil,
1500 miles dino
4500 miles with Mobile 1

next change will be about 8000 miles with synthetic.
Then every 4000 miles or sooner.

I agree with you on this. The people who built & tested the engine know better plus you stay within the warranty requirements. I also like the onboard engine condition analysis to remind me as well.

I go with this procedure. Any of these will get me to change the oil(normal duty only, off roading I would change more often):

1) Do what the owner's manual says (no more than 6 months or 8,000miles plus what weight/viscosity oil to use)

2) Check the oil level, color ect. often. If it is low or turns dark in color I change it.

3) On board computer says to change it. Don't forget to reset it.

PS Following the above, on the vehicles from work or I have owned that have the oil change indicators, the indicator had me change the oil almost every time. The only time that it didn't was a 2008 Honda Accord. Although the oil level and color was still good, I changed it at 7,300 miles from the previous oil change.

I checked my oil for the first time last night it was full and in my opinion looked very good not dark at all 750 miles or so

I think the first post is about that 2013 has now changed back to 5W20 while 2012 was 5W30. The change is a surprise to me.

I think there is no change to the engine in 2013 other than the ticking fix, so why they changed it to 5W20 in 2013?
Or if we're continuing to use 5W30, as recommended, in 2012, it will eventually cause problems?

Using a quality 5W-30 in the 2012 Pentastar will not cause problems.

2012s are 5W30 but I am sure if the 2013 calls for 5W20, the 2012s will be fine on it, an Chrysler may back-spec it. I am running 5W30. First change was at 750 miles with Pennzoil non-syn, second at 2,000 with the same, and third at 3,500 with Pennzoil semi-syn. I'll probably move fully to Pennzoil Ultra 5W30 or Castrol Edge and do ~5,000 between oil changes, depending on driving. I'll keep a shorter OCI as I hit more dirt roads and trails.

I hear that "some" 5W20s are very shear-stable and that many 5W30s break down to and past the 5W20 level very quickly anyway, so the better 5W20s are the ones for me to now research and find. I'd be okay with using them.

I wouldn't unless you are told so by Chrysler. Changing to 5W20 could possibly void the warranty since your vehicle calls for 5W30, and the engine has known problems. Yes it sounds stupid, and internally with the exception of the supposed fixed head I bet the engines are identical. I'd wait till they back spec the 2012's to 5W20. Honestly I don't see it happening this soon. Chrysler has their hands full with the ticking head issue, the last thing they need is to cause confusion, and generate questions as to why the change for 2012. I also believe 5W30 is the better choice, 5W20 was probably CAFE motivated. JMO

Has anyone seen any documentation on whether they are now recommending 5w20 of is it all heresay from dealers service people. I changed mine at 1800 on my 2012 and used 5w30 just like its says on the cap. Plan on changing at 5000 again. I didn't reset my oil change monitor I just want to see how long it will go before it comes on. At 4500 now and still no light.

The 2012 calls for 5W30, the 2013 5W20. IMO the change was all about CAFE and nothing more, the thinner oil will net a fraction of a mpg more, and will make the mpg numbers for the fleet of Chrysler cars better. That looks good for Chrysler in the EPA's eyes. If it's better for the engine or not is always a hot topic for debate.

Remember you have a warranty to deal with and an engine with a known problem. Using the wrong viscosity could possibly cause warranty issues, its not worth it. If you own a 2012 use 5W30, a 2013 use 5W20. I'm sure the engine will have no problems with either grade, but I wouldn't tempt warranty fate. Now if Chrysler issues a TSB or back spec's the 2012 to use 5W20 then you can use it.

Maybe they changed it. 2011 3.8L used 5W20 ONLY according to the 2011 owners manual. My 2012 has 5W30 printed on the oil cap. Maybe they went back to 5W20 for the 0.001MPG bump, and to help the cam phasers and valvetrain hold up better.

They definitely changed it, why exactly is anyone's guess. I think it was more CAFE than anything else but that is just my opinion. I look at it this way, if they really thought a 20 grade oil would help protect the ticking heads they would have back spec'd the 2012's. At a rate of 500 heads per week failing if a change in oil viscosity was going to help they would have back spec'd them all, at this point they haven't back spec'd any.

I agree with what you are saying. Until I SEE it in writing that I am supposed to switch to 5w20 I'm sticking with 5w30 like it says.

The dealer I went to do complimentary oil change put 5W20 into my 2012. I argued with the service manager for 10 minutes about they should use only recommended grade and they put my warranty in risk. He said they used 5W20 in all vehicles, they didn't stock 5W30 other than synthetic (I wouldn't believe that) and after all they refused to changed it back to 5W30.

I emailed the Chrysler customer service, they said 5W30 was recomended, but neither confirmed 5W20 in 2012 was OK nor the dealer was wrong to use 5W20 and only repeated that THAT dealer (they didn't say all dealers) would honor the warranty regardless the 5W20 oil they used.

I replace the oil with 5W30 myself the other day.

Relax it was a joke...

I was reading around here some guy hasn't changed his oil in 300K mi, just adds a can of "restore" or some shiot.

If this was a different site I'da called him out.

Just had a dealer oil change on Friday. (Get 8 free with a new Jeep).. I too ask about the weight in my 2013 Wranger.. Is it 5w-20 or 5w30, he said it is 5w-30 but he would double check with the oil change tech.

Got the page (Calling Mr. Smith, your Jeep is ready in service) to the service counter, your new Jeep is ready to go. I asked again about the weight, he said 5w-30. This morning I raised the hood to see if there was and oil spill or mess anywhere. There was, and right on the frecking cap it said 5w-20.. This is why I do my own stuff to the cars and motorcycles I own.

I'm going to give them a call on Monday and see if they will give me the remaining 7 oil filters, and they can stick there service up there a--.

Will 5w-30 hurt anything, I don't think so. But the dealer should know his product.

Wow, I feel better already...

The dealer should know his product your joking right. The dealers know how to sell Jeeps and that about where the knowledge ends.
I got 5 free oil changes when I bought my 2012 jeep, after the first 2 of them I asked how much more would it be to switch to synthetic oil. They said $25.00 so I had them do it for my 3rd free oil change plus the $25.00.
When I got it back and looked at the work order it said they changed the filter and added 6 qt of Mobil 1 10w-30. Do any of you see that on your oil filler anywhere? No when I asked why they told me that's what we use here. The dealer should know his product ya right.

I am a stong advocate of changing oil several times near the begining to "rinse " the motor. I have a little over 600 miles and I changed the oil twice already. I'll probably go to full synthetic at 3K to 4K miles.

By the way.. the 2013 owner's manual says 5w20 is recommended, not obligatory. A 5w30 would be fine.

Wow, 5, 10, 15,000? I know this ain't the old days but lets be real. That's a lot of miles between changes. They recommend longer service intervals to keep the "cost of ownership" lower and to keep the carbon footprint lower by using less oil. It's for the damn tree huggers and bean counters. Any car will hit 100,000 miles these days and they could care less of failure after that. Besides longer intervals and super light oils would be fine for cars. But this is a Jeep we are talking about. You could drive all day on some trails and put on only a couple hundred miles. If you waited for that magical 5-10K before a change you could be risking damage. I would rather change my oil based on hours and conditions.

I think he was saying he changed the oil every 5k miles.
IE oil changed at
5k ,then again at 10k then again at 15k ect ect.

The way I read it is that they "recommend" 5W-20, but the filler cap overrides that recommendation... so replace the filler cap if you want to run a different viscosity.
