Jeep Wrangler 392 Oil Filter

[guruman]

Magnuson act prohibits a manufacturer from voiding a warranty due to a different brand of oil. Also, I think the filter type is dependent on the dealer. I’ve had 2 Jeep wave oil changes. The first, they used the 899. The 2nd, they used the 041 (SRT) Pennsludge both times.

I know it's a fine point of contention, but .... You're right a different brand would remain protected by the warranty act, but a different specification (wrong weight, wrong SEA number or whatever) would definitely get the warranty voided. I've only heard of the Pennsludge.... and someone posted a blurb from an Amsoil rep that they had an oil that "met" the certification.... which in my mind is not the same as certified. I'm not aware of any others that meet the requirements... FWIW.

I did not realize there was a law for it. Either way, my local dealer, who I have purchase 4 SRT vehicles through, does not carry the SRT filters. They do not stock them in parts and wont use them for oil changes even if I provide them. Their sales department is spot on but their service is absolute garbage.

That’s interesting. They’re moving SRT units but don’t hold the parts?
You said it! Garbage.
That’s like a hotel not stocking Reach-back.

I know about the grade/viscosity requirements. Forgot to get in the weeds on that one.
I think only mopar oil and Pennsludge carry the Chrysler approval.

I think there’s a few other “approved” options:

Complete(?) list of SAE 0W40 oils that have FCA Material...

Please correct and add others as you come across them. I am hoping we can keep this list fairly up-to-date and most of all accurate. Note: It's hard to tell from a manufacturer's website if their product is actually licensed by FCA (now Stellantis) SAE 0W40 APPROVED AND LICENSED Oils ONLY ...

I read through this whole thread, front to back, back to front, and front to back again...

And I'm more confused than when I started!

I'd like to do my first oil change sometime in the next several days. What filter should I plan to use so I can get it ordered?!

339, 899 or 041
The 339, is the original stock size.
The 899 and 041 (SRT) are slightly larger.
The anti drain back valve differ between the SRT and the other two.

The 339 is smaller than the other two, this leads people to believe the bigger ones are better with more filter area. They all 3 certainly fit and seal without leaks, been tried countless times by forum members here. Scott Blum is on all of the Facebook 392 groups and claims to be a big part of the 392 development team at Jeep (I believe him). He has said that the larger filters can get damaged by framing/suspension components under hard acceleration/deceleration as the engine tilts on its motor mounts. I have used them all at this point.

I’ve seen members reported 041 damaged. Been using 899 and it’s a bit shorter at the bottom edges than 041. Love it so far.

Very strange that some see damage and others nothing?
392 cubic inches vs 220 cubic inches I’m definitely going to try the SRT and AMSOIL as well, I have ran the AMSOIL in the 3.8 supercharged 80,000 miles, the 3.6 tuned 30,000 miles, pulled over 2000 lbs many times with cruise control set on 80-84 mph for hours, neither ever used a dropped of oil, lost power, and no catalytic converter issues whatsoever…

Thanks for the detailed replies.

I think I’m going to go with the MO-899. It’s readily available at the local AutoZone too.

Oil changes are easy enough and cheap preventive maintenance. I plan on doing them a little more frequently on the 392.

I guess I would like to see the damage and what is causing it. I have not had any issues with the 041 and I drive hard, on and off road. Where is the filter making contact? Is it right on the frame in front of the filter? Suspension components? I am just curious.

What I read was more specific but cant remember. I still have the 041 installed, not sure what I will do next time.

Yeah something is not right, don't make sense for one Jeep to make contact and another not have any issues? Of course the guy that had the issues never posted any photos of the damage either, he may have exaggerated the contact of the filter with the suspension....

It seems like my new role is the warranty police. But I will let you know that the 392 explicitly calls for an oil change every 6 months or 6000 miles whatever comes first. That is pretty frequent. It uses the term “under no circumstances” which is a little over the top. But on my 5000 mile 392, I have changed the oil 5 times…. Oil looks the same coming out as the new stuff going in.

Anyone have a 392 using oil? If so how much?

Yeah, I do appreciate you pointing this out too. I was familiar with the oil change schedule as set forth by the manual.

I’ll be changing it at least that often, but most likely more often. Planning my first change at ~500 miles and I’ll be replacing the drain plug with a Fumoto valve and installing the Artec oil pan skid at the same time.

I used the 041 SRT on my first change. I like the idea of retaining oil pressure after engine shuts off, that way oil gets to top end faster on restart.

SRT Engineers:
"The SRT Viper filter flows better than the stock purolator filter and requires a higher differential pressure to bypass the filter at cold starts and high demand (Meaning the SRT Viper filter bypass stays closed more often and filters more oil). Both filters will work on the 5.7/6.1/6.4."

When an SRT owner takes their vehicle to a driving event with the specific intent of exploring the far reaches of the performance envelope, they can rest assured that the 6.4-liter HEMI engine will sustain proper oil-pressures in extreme cornering conditions. For track-day use, SRT engineers suggest using the SRT oil filter(part number 05038041AA). Originally designed for Viper applications, it works great with all Chrysler V8 engines. The SRT filter features a higher differential pressure bypass valve and reduced pressure loss across the filtere lement
____________

"From the SRT Engineers:

The SRT oil filter for all the past engines and the new22mm inlet SRT filter for the Gen 4 and beyond engines share the same characteristics. We worked with many of the filter suppliers to get the best features. Some fell out for various performance reasons but we ended up developing the current SRT filters with one of the mainstream manufacturers (it is different than their commercial offerings - or at least was when we developed it). The high flow oil pumps in our large engines (Viper is the biggest) can overpower the internal relief valve. When this valve opens it allows some of the high pressure dirty oil to bypass the filter element in order to keep the filter from being damaged. The SRT filters do indeed have a higher differential bypass valve to make sure all the oil delivered to your powerplant is clean. The housing is slightly thicker than many of the brands out there to handle the pressure but is not the thickest. The real thick ones failed our development testing (fractured at the crimped flange). The media used was one of the latest synthetics that allowed very fine filtration, more debris capacity, and much lower restriction than our standard Mopar filter (and just about every other filter out there).

I've had my larger filter on for a month now with around 800 miles on it. I've had no issues with clearance [or leaks]. I do not know if there's an angle adapter that came stock with the vehicle, if it was there it had no negative impact with regards to the larger oil filter. I watched the dealership install my filter (and perform their inspection- I was under the lifted vehicle with them) and at no time was there a concern about an angle adapter nor improper filter fitment. The old [smaller] filter came off, the new [larger] filter went on.

Hi,
I read a lot of the comments and bought the SRT filter 5038041AA
It fits but with little clearance
I chickened out and used the original one, part number ending 339 (that was was was in it)
There was no room for the filter wrench, maybe a business card would fit
