Hi gents. Want to use the factory installed oil filter. I searched and searched and my little heart is a hurtin' with the differing takes. Which came stock in a '23 392: 339AA, 339AB, 339AE, or was it the 899AC???

HELP!

Also, do I need to buy a washer/gasket??


Sorry, please, and thank you.

The factory installed filter part number is printed on the filter. Most folks on here are using the larger SRT filter on DIY oil changes, myself included. No you do not need to buy a washer /gasket. The factory drain plug has an integral gasket.

The letters at the end of filter number have changed. I asked the dealer why they said a vender change forces a different AB, AC or what ever the new vender uses .
Give the dealer your vin number, the parts department will give you the correct filter,no washer or gasket other than the one attached to the filter
 
Or find it at any national auto parts store / retailer under the general name of mopar MO-339

Thanks. I read that thread along with several of the others I found. No interest in going to a Wix or Mobil. Want to go OEM and give the dealer/Jeep no chance of giving me grief for doing my own maintenance.

Hi! Thanks. I can't see the filter number with it in place and I don't want to find out once its out and wait to find an exact matching one. I read about the SRT filter too but it being larger doesn't really make me all that excited. Just want a carbon copy of whats in it already.

Ahh! Thanks for letting me know about the gasket! No one wonder no one talked about it.

Oh! Thanks! Perfect answer. Thank you. Now I know! I was trying to avoid going to the dealer altogether but I guess I'll go to the parts and ask. Gaskets on the filter itself??

Rubber type o ring pressed or crimped onto filter. Always check to make sure it is on the old filter when you remove it. How ever I have been changing the oil in all my vehicles for 48 years and never once have one of those rubber gaskets not come off with the filter as they should. But I always check. When I was 16 and just starting out an old timer at a Napa auto parts told me to always check so I do. Now I feel like I’m the old timer.
 
I’d suggest to go with MO 899. It’s the one used by dealer on Scat Pack, 5.7 HEMI… I’ve been using it for 5 oil changes. Perfect fit and bigger than the 339.
I read about that one too! People said its a tad wider at the connection point. Is there any benefit? I just want to avoid any hassle from the dealer if I ever run into a warranty claim.

Thank you! I never knew about Rock Auto until recently. I am going to go to the dealer on Monday and give my VIN and see what they say. I trust Rock Auto is legit? Seems highly regarded.

Thanks everyone so much for helping me despite it being a topic covered many times over.

I've been getting most of my auto parts there for many years. You pay for shipping but it is still usually cheaper than most other places. Also, shipping is my least favorite bit with them - they ship from multiple warehouses and you pay shipping separately. So I try to combine where possible, for example if there are a couple different name brand part options I put them both in my cart and see which one matches my other items.
They also carry the Mopar 392 air filter which is hard to find anywhere except a dealer.

Unfortunately they will recommend the MO-339 (smaller filter which all of these new vehicles are coming with from the factory).

I just went through this yesterday at the dealer where the service manager is a good friend of mine for years and their service department has really been excellent to me.

I have several Jeeps all V8’s and they have been servicing my 2011 JGC Limited 5.7L since I bought new which now has 220,000 plus and runs like a champ - All Original - Amazing Vehicle.

So here is what I was shown on the service managers computer for all of my vehicles:

2011 WK JGC 5.7L - Filter MO-899 with 5W - 20 Synthetic Blend - This has been since day one when I bought it and continues to be the recommended service.

2022 WL JGC 5.7L - Filter MO-339 with 0W-20 Full Synthetic

2023 20A 392 Wrangler - Filter MO-339 with 0W-40 Full Synthetic

I had the 2011 and 2022 Grand Cherokee’s serviced yesterday - I requested they install the MO-899 on the 2022 WL and they said I would need to sign a waiver and if there were any issues Stellantis would most likely void my warranty - My service manager told me not to do it especially since I change my oil religiously in all of my vehicles at 3000 miles or every six months with the 392 since to date it has not been driven enough to come close to 3000 in six months.

In summary we discussed all of this in detail yesterday and it’s simply Stellantis that is specifying and more or less mandating the use of the MO-339 on many of their vehicles simply because it’s “cheaper” and easier for them and not in the best interest on any specific vehicles - Shame on Stellantis especially with the 392 which is basically the SRT and should have the larger SRT filter - Period!

The 5.7L Hemi in the 2011 JGC is basically the same Hemi engine as the 2022 WL - Stellantis changed the oil spec and filter spec on the 2022 and continue the original oil spec and larger filter spec on the 2011 which is all noted on my service tickets.

Personally, I believe the 2022 5.7L should definitely have the MO-899 Oil Filter and the 392 should have the MO-899 at a MINIMUM.

FOR NOW, I am sticking with the factory specs simply to comply with warranty.

BTW - I hate the LITTLE Filter MO-399 on these large V8’s and believe they are inappropriate for these size engines - Especially long term. Another case of bean counters and corporate greed in my book.

Sorry for the long winded post however maybe it wil be helpful to others✌️

Ah so the other shoe drops! I appreciate the tip. Now I know what I am looking for on the site. Good stuff. Thank you

Thank you for the insight. I appreciate it. I think I am in the same boat and will do what the dealer says or what is in the vehicle now just for that warranty stuff. I honestly take care of my vehicles but don't hold onto them too long but this one.. feels.. different. I am liking it a lot. And if ownership shows me that it can be anything like your 2011, then I am going to hold onto it. Just reading some stories of the unreliable nature of the brand has me a tad shook but so far its proven to be fantastic. Thanks again for all the info.

Edit: Wish you were in NJ or NYC so I could ask for that dealership's info. Argh

Just to give you some peace of mind the owners manual is what matters as far as following required maintenance while you’re under warranty. Dealers will often upsell or do the bare minimum or “require” service items that aren't actually “required” at all. Ultimately it’s Jeep who actually warranties the vehicle… not the dealer.

The owners manual says “Recommend Mopar oil filter or equivalent” there’s zero “requirement” to use the M0-339. You obviously can and it’s not a big deal if you do, but there’s other options that are better filters. Some dealers will just follow the service manual and another dealer will use other available Mopar options for filters if you ask.

You can always just do it yourself as long as you’re using an equivalent product. Service departments are all franchises just like the sales side. I often trust none of them. Most of them simply care about their bottom line which means they do what is the most efficient for time and cost effective for them… not what is necessarily best for your vehicle.

Just some food for thought using a different filter doesn’t void your warranty. Mopar doesn’t actually make any filters, another vendor manufactures them for them and slaps Mopar on the filter.
