Look on the label of Pennzoil Platinum 5W30. It states it meets the MS-13340 standard.

Yup, thanks; there it is now:

Like I said, two years ago when I was first researching this, that wasn't on the bottle yet. And no definite reference anywhere else from Pennzoil...

So good to 100% know there's a equivalent now to the Mopar oil...

i have a 2021 trailhawk as well

my oil light comes on every 6000 miles so far been thru 2 oil changes.

That may be because you're driving under some kind of adverse conditions...? Short drives? High temperatures? Towing?

 

[Marek K]

OK, this is interesting...

We all know that oil changes are dependent on driving conditions. But in any case oil changes need to be done at least once a year. And the Oil Change Indicator is supposed to reflect that.

Since we're retired now, we're doing a lot less driving than we used to. My first annual dealer oil change on my 2021 Trailhawk was on 25 March 2022, with only 4,530 miles on the Traihawk.

I know it's been a year, so I'm going to make another appointment for this coming week.

The Trailhawk now has about 7,600 miles, so I've driven it even less the past year. But it's now been one year and one day since the last oil change. And I just started up the Trailhawk in the garage, and I'm not getting any warning chime or message in the instrument cluster. I'd expect that I would, even one day after the one-year interval.

Is there any way to check on the interval? I don't see anything int he Owner's Manual...

 

[goodshepherd]

yah just local city driving mostly, thats when the light came on, no clue

did the free dealer oil changes (had 2 done now) and im on 14k right now.....


i also changed my air filter myself after each oil change....

(old habits die hard)

this is prolly way too much air filter changes but i have it programmed in my brain lol


I would think if you were proactive to change it every 5k if it says or not lol

ive been waiting for the oil light.

I know what you mean. I'd say every six months is a bit too often -- depending on your driving conditions.

Jeep, of course, only recommends engine air filter changes every 2 years or 20,000 miles. I've always changed air filters on our VWs annually -- just because it's easy to remember. And that's what I'm doing with the Trailhawk.

A year ago I change my Trailhawk's filter myself, and I don't think it was too soon -- old filter on the left:

Again, that was after only about 4,500 miles. But we do a lot of offroad driving.

By the way, where are you buying your filters, and for how much? I got a bunch from the UK; much cheaper when buying several than here, even with shipping...

Oh... And since you change your filters yourself... Have you noticed this pleated fabric insert in the upper filter housing, just above the filter itself?

What is that? It doesn't look replaceable, though I'd think it should be. At least it's on the "clean" side of the filter...

From what I understand, the light does NOT come on based on the one year time interval, nor by the 350 engine hour limit. It only comes on based on whatever algorithm is used to monitor oil life.

You can find the oil life percentage remaining using AlfaOBD.
First connect to your vehicle using AlfaOBD and chose your vehicle, then connect to the engine module.

Once connected to the engine module, tap the "Battery" icon at the bottom right of the screen:

Then tap "Read System Status":

Scroll down until you find "Engine Oil Life Remaining" (for me I had to scroll down about 1/3 of the list):

I believe the change oil light will come on once the remaining life hits 5%, so at 6% I'm almost due for a change.

That's strange, since as you know the Owner's Manual says: "The oil and oil filter replacement must be carried out when indicated by a warning light or message on the instrument panel, or in any case should not exceed one year or 10,000 miles (16,000 km)."

Oil breaks down over time, not just with use. So it's really weird that the warning wouldn't come on for one year... I assume it would come on for 10,000 miles...? Not that I'm ever likely to drive it that much in a year...

The reminders in our two 2009 VW Mk5's comes on after a year, or with mileage.

And where do you see 350 hours of engine running?

Thanks for the AlfaOBD info. I've never used mine, and I don't think it's worth hooking it up for this (does the SGW have to be bypassed to see this particular function?).

I'll ask the dealer about this next week; meantime, it's easy enough to remember the once-a-year part...

I read it like this:
The oil and oil filter replacement must be carried out:
1. when indicated by a warning light or message on the instrument panel
OR
2. should not exceed one year or 10,000 miles (16,000 km).

You don't need to use the bypass since this is a read only function. It should only take a few minutes (if you can find it in the seemingly endless list).

OK, that's a reasonable interpretation.

I just think that it'd be simple enough to include a simple time and mileage counter in the system. Since the time and mileage limits are "in any case." Otherwise someone may be waiting for the warning to come up, and wait longer than a year or 10,000 miles. I'm not sure that would be a good idea...no?

Looking at your screen shot, it looks like it can track at least mileage...at least elapsed since the warning comes on...

You don't need to use the bypass since this is a read only function.

That's good to know. I may try it, as my first foray into AlfaOBD...

Update on the 0w-20 oil change,
The dealership did get back with me when I finally replied to multiple requests for a review... long story short there has been a revision to the oil recommendation for the 1.3L DI turbo engine. The new recommended oil is 0W-20 ACEA C5. I attached the Mopar docs.

Still trying to understand why they dropped the oil change interval from 10K miles 1 year to 5K miles 6 months which pretty much defeats the vehicle's oil service indication.

Interesting.

First, where are you seeing that the current recommendation is 5,000 miles or 6 months?? I've always changed oil in turbo engines every 5,000 miles -- but I'm not currently driving that far in a year. In 6 months I'd only be driving about 2,000 miles... Why would oil wear out in 6 months?

Second, what's the difference between "E6D Final versions" and "E6D versions"? Because the original MS-13340 0W-30 is still listed for the latter -- whatever that is -- along with referring to the oil filler cap...

I'm not sure I'm comfortable with going with a lower temperature rating in a turbo engine...

And I notice that the part number listed there for the MS-13340 (68291576AB) is different than the part number on the one bottle I have (two years old) of MS-13340:

 

[Marek K]

You can find the oil life percentage remaining using AlfaOBD.

OK, so AlfaOBD learning-curve time for me. First time I've fooled with it. And already I'm lost, even referring tot he fine AlfaOBD instruction online.

I've got the PC version of AlfaOBD on my laptop -- looks like you're using a cell phone version.

I hooked up the PC to the Trailhawk's OBD2 port using just my OBDLinkEX cable:

Turned the ignition on (not the engine).

Clicked on AlfaOBD, and allowed it to update.

On the initial screen it was already showing JEEP and RENEGADE (BU). I chose the ENGINE fuction, and got this:

So how do I know which ECU I have? Obviously not the diesel ones, or the Tigershark ones (with my 1.3T engine).

With all the others, when I click "Connect," all it gives me is a screen asking me to choose my Bluetooth device.

What am I missing? Do I need my "Grey adapter" for this?

* EDIT *

I went back and played with it some more.

First, I went into "Advanced mode," and found that the Interface was set to Bluetooth. So that would explain why it was trying to Bluetooth-connect.

So I set it to USB OBDLink SX/EX. COM3 is the only COM Port choice:

But no matter which ECU I tried to "Connect" to, I kept getting the same error:

Whether ignition in RUN or engine on. With or without the "Grey adapter."

OBTW... I realize my 2021 Trailhawk is a BV model, not BU. But BU is the only Renegade choice on the screen...

I've been doing some more digging into this. Maybe some of you European owners can help.

Apparently the Euro 1 through Euro 6 (E1 - E6) designations are European emissions standards, chronologically since 1992 (I've lived in Europe twice since then and I've never heard of these standards):

Euro 1 to Euro 6 – find out your vehicle's emissions standard | RAC Drive

The latest standard is apparently E6D, as of 1 January 2021:

New Euro 6d emission standard: Audi has converted its model range | Audi MediaCenter (audi-mediacenter.com)

I'm not sure whether those standard meant actual design changes in engines, or just emission standards. It makes sense that a generally thinner oil would be recommended for more-stringent emissions standards.

So, first, these are European standards, not applicable to us in North America. Second, my 2021 Trailhawk was built in February 2021; so I really doubt its engine (as opposed to the final assembly of the entire vehicle) would have been built under the E6D standard for which 0W-20 is recommended.

In any case, the recommendation that my 2021 Trailhawk and 1.3T engine came with is MS-13340 0W-30, which is still recommended for the E6 standard. So that's what I'm going to continue using, and insist on...

Those of you with more-recent Renegades... What oil recommendation does your Owner's Manual (and filler cap) show?

You can find the oil life percentage remaining using AlfaOBD.

Finally, got it!!

Turns out I first have to have the ignition ON, and AlfaOBD running on my laptop. And only then plug the OBDLink EX cable (without grey adapter) into the vehicle's OBD2 port. That may be a function of my particular laptop, since I have to do the exact same thing with VCDS on our Volkswagens ever since I got this new laptop.

Anyway, the procedure is a bit different with the PC version than with your cell-phone version.

First, I need to select my engine ECU. The only one that connects is "Chrysler Tigershark/Pentastar: Var.1." YMMV.

Then I click on the "Status/Faults" tab, and then clicking "Read System Status" I get the same long list:

So this shows 54% of oil life remaining. Which makes sense, since I've only done about 3,000 miles since the last oil change a year ago.

Except, of course, for the part that oil change "in any case should not exceed one year." Which should mean that about 0% of my oil life is actually remaining.

So it's very evident that the oil change indicator doesn't take into account mileage or time. It would seem trivial to have made it do so...

Anyway, I've finally gotten AlfaOBD to do something. Thanks!

And by the way, it looks as if it would let me erase any error codes without going through the Security Gateway. I didn't have any codes, so I couldn't check that. But that would be great, since that's one of the primary reasons I got AlfaOBD...

 

[georgef]

Finally, got it!!

Glad to hear that.
I don't have the PC version of AlfaOBD, but I do like the looks of that screen layout. I may have to invest in that version too. The Android version is handy because I usually have my phone with me, but the PC version looks like it would be easier to navigate.

 

[Marek K]

the PC version looks like it would be easier to navigate.

Once you figure out which engine ECU you've got...

So what's up with that battery icon on your first screen?

 

[Marek K]

Well, I just got back from my second annual dealer oil change.

I specifically asked the service manager whether there had been a change to the recommended oil for the 1.3T engine -- I specifically asked about 0W-20.

He said, no, there hadn't been any change; they still use MS-13340 0W-30 in bottles from the parts department.

He (kind of proudly) proudly pointed out that it's a "European oil." Um, OK... it's for Fiat and Alfa Romeo... but it's still packaged in one-quart bottles...

Oh! I was finally able to get them to install the Valkyrie front skid plate that I'd had for two years -- they couldn't install it last year because I didn't have the correct bolts and spacers.

This thing has removable access plates to get to the oil filter and drain -- that's the main reason why I got it -- I don't want to be dropping the skid plate when I do oil changes myself after next year.

Plus it's 3/8" thick, as opposed to the OEM 1/4". Plus it doesn't have the cut-out under the oil pan -- maybe 3/8" less ground clearance at that point, but gives much better protection...

 

[Marek K]

From what I understand, the light does NOT come on based on the one year time interval, nor by the 350 engine hour limit. It only comes on based on whatever algorithm is used to monitor oil life.

Yup, you're correct. In addition to being evident from the AlfaOBD System Status, I just stumbled on the specific cite. 2021 Owner's Manual, p. 353:

NOTE: Under no circumstances should oil change intervals exceed 10,000 miles (16,000 km), 1 year or 350 hours of engine run time, whichever comes first. The 350 hours of engine run or idle time is generally only a concern for fleet customers. NOTE: The Oil Change Indicator will not illuminate under these conditions.
