Here's my latest...iron was higher than 'normal' but I also noticed this is the first winter analysis done as well (others were from oil changes from other times of the year than Dec-March, the coldest part of the year here).

5w30 Castrol Synthetic w/ Luqimoly MOS2 and Mopar SRT filter.

That is disappointing, in case someone cant see what happened I'll post the relevant stuff.

OCI 3 intervals ago

Miles 4400
Moly 300
Iron 6

OCI 2 intervals ago

miles 5,000
moly 283
iron 7

Latest OCI

miles 5100
moly 272
Iron 36

Everything else is great as far as wear numbers. This is why you get uoa's imo. I would put that strategy on a short leash if it was me, the engine is in it's best life as fa as miles and wear numbers go, right at 100k miles imo this shouldnt have happened. I might considering changing my strategy if this continues, I might be inclined to drain a little off and test it before changing the oil next time. At a minimum I would increase viscosity, at 100k miles no reason to use 5w20.

I've not run 5w20 since 75k miles.

Nothing has changed, strategy wise, since I switched to Castrol, MOS2, and SRT filter at 75k miles. The only thing changed, literally, is time of year the sample was taken.

Burla · Mar 27, 2022

That wouldnt increase iron, once iron wear is created it doesnt go away. That is a thin 5w30 as it is in the 9's. So something in that engine is off. Not only iron wear up substantially but viscosity is shredding more then the prior two, especially if that is the same oil in last 3 runs, the other two runs oil was in the 10's visc.

Maybe it's a precursor to a lifter failure?

I'd hate to have to get a 6.4 to install. I mean, it'd be so horrible, and I'd just hate it so much!

HEMIMANN · Mar 27, 2022

It's weird PQIA doesn't include the Valvoline Advanced in their test index - only shows on searching for it.

Latest on my 19 Ram 5.7 Classic
Redline syn 5w-30 oil
Royal Purple 20-820 filter
I’d say 80% highway miles

Excellent report. It's weird the bearings are taking so long to wear-in, maybe due to the extreme lubricity? Iron is coming down too.

While it shows you can go long OCI's, I'd suggest reconsidering that, knowing these engines have valve lifter lubrication problems.

Burla · Apr 15, 2022

You increased the interval by 30% and had wear go down, even though it is high wear, what you have is young engine stuff going on, I don't see a worry per say. Looks like mine, first page. Did you have hemi tick? Aluminum is coming way down. I think you are heading in the right direction and this interval is good, perfect tbn level there to change. You can see blackstone is not that worried, as long as it trends down you are good. For guys who cant download that he has 4 reports from new, copper in the over 100ppm range but drop everytime. For me the puzzling one was the aluminum, but it seams to have seated well so I just let that go. What was that first oil with 200ppm moly? factory fill? The loss in viscosity was just due to that being 2-3k miles over the last intervals.

HTXRamExp · Apr 16, 2022

The first was the factory fill.

I don’t intend to run such long OCIs, this one was about 2k longer than I had planned on.

The only time I would get tick was after the truck sat for ~4 weeks while I was away at work, and even then only the first couple seconds.

I have a 2019 2500 6.4 with 23,000 miles. I have used PUP 0w-40 the entire time. All have had mopar filter until the last change, I went with RP 20-820. First oil change was around 2500 miles and every change after that has been right at 5000 miles give or take a bit.

I have no tick other than on 1 random cold start at work a month or so ago. My question is should I stay with what I'm doing, or add some lubeguard to what I'm doing, or go redline??

If redline, what weight? I just don't want to start having issues. Also, I am going to look into Blackstone labs for oil analysis.

Thanks!!

5W-30 It gets stiff enough in the winter to clatter the weakly oiled valve train, guys have gone to 0W-30, but Red Line is messing with this formula adversely. Long story. You're in Iowa = 5W-30.

imo, it is good to have a move in the bank, since you have no issues I'd stay put, that is a good oil- top shelf. If you get an issue, then move to what hemimann says, that exact oil. Looking fowad to seeing you uoa, that will give us a good idea on what to do as well.

KKBB · Apr 17, 2022

Thanks guys. I'm gonna order the kit from blackstone. I might wait a bit to take the sample just to see where it will be numbers wise closer to the 5000 miles I usually change it at.

KKBB · Apr 17, 2022

Also, do you guys drain some out the drain in the pan, or use some type of vacuum pump like blackstone sells?

Burla · Apr 17, 2022

As the oil is draining after a qrt comes out I fill up the tube to the top, not hot but a little warm usually.

KKBB · Apr 28, 2022

I got my sample packs from blackstone yesterday. I will change oil in less than 1000 miles on my 6.4 and send it in. I will be changing oil on my wife's 5.7 durango in about 2000 miles and see how it is. Hers might come faster than mine based on how much she drives.

clint440 · Apr 30, 2022

First sample of RL 5/30 but on second oil change of RL 5/30 at 9500ish miles on the oil. Contemplating to run up 12,000 and change?

Burla · Apr 30, 2022

Real interesting uoa thanks for posting it, looks good to 12k miles imo if same type of miles, I expect copper and iron to come down. Very interested in seeing more of your uoa's.

HuskerRam · May 3, 2022

Valvoline EP 5w-30 with 6k on the oil and a RP 20-820 filter. Ram smooth and a little quieter than the QSUD I ran religiously before. I’ve been running 5w-30 for the last 50k miles and it seems to be doing ok.

HEMIMANN · May 3, 2022

Wow excellent report, thanks for sharing. Your iron is waaaay low for a Hemi - your motor is tight and well worn-in.
You can beat on it more! ha ha

Nice slug of moly (200 ppm is peak effective according to wear study Burla's shown), and zinc additives. More and more oil makers are getting religion and adding soluble moly for those engines with marginal lubrication areas like Hemi valve lifters. Looks like the older API SN additive pack with high calcium and low magnesium? SP should be the inverse.
