Interesting on the VVT report. Let us know if it continues. Our Jeep has the VVT 3.6 in it like ever other vehicle. Do you have an actual filter or a canister style?
It's actual filter like our trucks. I've cut every one open looking for anything and the only one I found was on the one from the dealer that changed the oil right before I got it. There was definitely some sludge in the filter. Not terrible but it was there....

This will be the longest I've run on the R&P so ill see what it looks like this time. Thinking of going to 3k, maybe 4k idk...

Yes, the facts have not changed that I know of. Just based on filter and flow the forum likes fram xg2, fram fe2, RP 20-820, puro boss number unknown to me, amsoil ea. See oil filter thread for more info, this is not every guys list, some guys favor Mopar srt. On a 5k miles or more interval I would stay with 100% spun glass, anything else is likely to stiffen up. Any others I am missing fellas? If you get amsoil ea use the large one.
Thanks for the info :)

Might not be a bad idea since you have no clue on the oil change history. I still only go 5k on our Jeep and I am the only one who has touched it. I see no sludge when I drain it. The drain plug looks great. The filter is always black when you take it out, but I never see sludge in it either.

Yup same here with my wife's Jeep, 5k intervals no matter what oil I use.

My Flex was maintained very well. I know the service and higher ups very well where I bought it. It was their Gold whatever certified, but I was guaranteed they did every oil change up to the 11k mark when I bought it. Any ways motor was super clean and didn’t make a single noise. It’s been ok with going 6k on it with Mobil 1 and a motorcraft filter. I have been advised not to swap from a Ford filter due to the chance of it causing issue that I have read. I’ve got a nice Mobil 1 filter for it, but I have ran the Motorcraft filter as I have on all of my Fords over the years with no issues. It is by far the best running of the two SUV’s we have. The only reason the wife wont drive it more is that it doesn’t have all the bells and whistles.

My personal opinion. Any oil that is not Redline 5w30, you should run it for only 3k - 4k.
This is what I'm doing with my truck and I'm keeping it that way. So far no issues.

The only time I saw anything metallic in my filter was after a timing chain and oil pump on my Audi at 60k and I changed it soon as I got it home 120 mi. But it’s my experience if filter changes were done in the mid point of a scheduled change it makes a difference in oil quality.In a def diesel I would do it but the carbon was over the top.

Because this is what Americans want?? The Fiat Titano and Peugeot Landtrek? Meat the platform that will be the ram 1200, or better known as the ram rampage. And might be built in China like the other two?

Badge engineering is alive and well in 2024, and this Ram 1200 is a good example of how a vehicle can suffer from a dissociative identity disorder. It takes the shape of a mid-size truck tied to the Peugeot Landtrek and Fiat Titano, both sold by Stellantis in different parts of the world. However, these three pickups have their origins in China where the new 1200 will be built.

This is where stupid meets stupider and then they have a baby. Oh they hit all the stupisest branches on the way down this tree. Di turbo that meets EV, lol? Built on hornet platform because it is so popular? Can we have paddles too yeah team?

So this was in may, but it is important to see what other countries get and what we get. Other countries get 6 speed or manual, reg cab or crew, and perhaps a straight di turbo. Some early information is the rampage which will be sold in USA will be di turbo meets EV = hybrid with a 9 speed transmission, of course to reg cab. This info is early, so don't hold me to it, but those other options look way more appealing to me then what America will get.

Even with the synthetic aspect? I don’t disagree here. Back when I first switched from conventional to Mobil 1 back in the 90s I ran no more than 3k but every time I pulled it the oil was still as clean as the day it went in. I wont go further than 5k and like in my LSX engine I run 3k max, but it gets bashed on sometimes and relies on E85 so 3k is really a stretch.n I did go a few oil changes with the ram to 6k on Castrol edge with zero issues but that was when it was seeing all freeway driving.

I gleaned from the Lake Speed Jr's videos that replacing the filter very soon after the first application of this cleaning oil is important. I redid the oil in mamma's Kia at just shy of 900 miles. The filter was fairly goo'ed up. Now, this filter is a canister type, and options ARE more limited. So, I use a factory clone.

It has been a tad over 2000 miles since I did this and the oil is getting dirty at the dipstick. So, I plan one more oil and filter very soon!

I'm now a couple of thousand KM's in on my latest OCI using only HPL SC 0W30 and the RP 20-820.
Buttery smooth and quiet HEMI, especially noticed on cold morning starts.

Here are dash pics of my temps and oil pressure after being on the highway for just over an hour at a constant 130Km/h, and then directly after coming off the highway to a stop light.

Happy HEMI, and the trans & engine temps are with the @caulk04 transmission cooler bypass mod installed as well.

Also, no AGS system in use as I have a Warlock.
Anyone know why the AGS isn't installed on the Warlock's as I'm just curious to know.

Thanks for reporting in.
As expected, a primarily PAO Group IV base oil provide the lowest temp flow capability. Now if there's enough AN to act like Red Line's esters without the cold flow problems, it could be a winner.
Both are dosed full of MoDTS, so no worries there.
With the spec sheet and this good field report, I continue with my plan to switch to it next year.
AGS? or ABS?

I'm going to take this run to at least 8,000Km's with this oil & filter and then send it in to Backstone and get the TAN and TBN done as well.

I'm thinking I may even go the full 10,000Km's (approx 6,200 miles) so we have a really good report for our database. I don't think this length of usage will hurt my HEMI.

AGS = Active Grill Shutters (I think that's the acronym used here for it).
I had them in my 19' 4th gen, but my new Warlock 4th gen doesn't have them.

I'm sticking with 5k miles regardless due to sensitivity of all the hydraulic orifices on these modern motors.
The slightest amount of contamination restricts and plugs oil flow to VVT, MDS, etc., and the corresponding oil gallies in their oil supply circuits.
Remember, a dedicated hydraulic system doesn't have an engine attached dumping combustion blowby into the oil reservoir like engines do.
The last thing you want to do is starve already starved Hemi lifter rollers.
Same holds true for the modern little turbo GDI motors. Don't want to restrict oil flow to those pricey turbo bearings!

For those who measure our OCIs in kms, often the standard by all manufacturers and dealers is 10,000kms or 5000kms.
So for anyone to use their oil till 10,000kms, sounds perfectly normal to me.
