Pentastar Owners! Any oil usage?

I'm not trying to sell you anything it's your car. I normally don't get too caught up in specs, but this one I've learned from experience to take seriously.

Here's the type of oil-related failure in a pentastar I'm talking about:

Thread 'Pentastar cam opinions'

This is my 20 Promaster 2500 with 85k. I bought it used in 21 with 30k (Amazon lease).

This is my work vehicle, I've run PP5w-30, and M1 euro 0w-40. All oils changed between 5k and 6k.

Oil filter housing oil leak so I tore into it. There is a lot of stuff in the way where they shoe-horned this pentastar where a Fiat 4cylTD was supposed to go.

Had to replace leaking radiator which made access much better for this application.

Found weeping valve cover Gaskets so decided to change those while I was there. Low and behold I see this. Some other cam lobes and rollers look similar. Not...

Finally found a copy of the MS-6395 spec for those interested.

Just FYI. If you're not going to listen to reason then maybe someone else who sees this thread will.

as @Glenda W. has stated, the ESP 0w-30 meets far more stringent approvals that provide better wear protection that any Fiat or GM spec.
 
That's what I keep hearing, but it makes no sense. Let's take a look at what the approvals are:
ESP approvals.webp


ESP is focused on emissions. I don't see any specifics about "best wear protection" either in the specs or even claimed in their advertising.

ESP doesn't meet Chrysler's spec. Chrysler engines aren't VW's. Saying ESP meets "more stringent specs" shows a lack of understanding. It's fanboying, really.

Whelp, you've convinced us all. Congratulations, you won. You can stop now.

Wear is not the issue with any fully-formulated motor oil.

That's what I'm trying to explain. This spec was created to address wear in Chrysler engines, and they do indeed test for it.

I would hope so. All licenses and approvals do too, with the same ASTM tests.

How do the limits of the test compare with the limits of an approval such as 504 00, which ESP has? I’d be shocked to find they are radically different.
 
I don't understand. You just told me that wear isn't an issue with fully-formulated motor oil, and now you're wondering what the wear rates are between the two specs.

I spent a little time trying to figure out the answer to your question. I couldn't find it. Really, why would a European spec run a test battery from the American Society for Testing and Materials?

Also, why am I doing research for people who should be doing their own due diligence, especially when there are so many good oils that meet Chrysler's spec?

The ESP formulation, and you can see looking through the certs, focuses on Euro emissions and LSPI. Another thing research shows is that the particular VW and Porsche requirements met for Mobil ESP don't meet requirements of their higher end engines. There are separate specs for those. If someone out there is thinking that because it meets an oil cert for VW means good enough for a Veyron means good enough for a Pentastar then think again. Anyway, since when is VW the pinnacle of automotive engineering?

People are getting too wrapped up in this particular flavor of the month. Euro FS, Restore and Protect, and now Mobil ESP is the new darling child. So far it's been 'nuh uh cuz reasons' and false equivalences, but I have yet to see technical evidence. Why don't you guys go ahead and give a technical basis supporting ESP for a Pentastar? You can't even explain yourselves. Somehow a product is being internalized into personal identity. Peak consumerism and strange.

You think so? What would support that notion?

Which ASTM or ISO test is applicable for determining 'psi film strength" in finished motor oils as used in an engine? Which of the Sequences performs those tests?

Some people just really, really want this sort of "ranking" to work, even though it will not. A screening test for certain additives is one thing but not for finished products.

Correct, there is no best oil. Both Chrysler and Mobil recommend against ESP in the Pentastar. It's so much simpler to run the right oil.

Yeah. So you have no idea whether the whole premise for your posts is correct or not. Just some weird bias.
 
I changed the oil filter assembly yesterday on my first gen Pentastar, and went with PPE 5W40 and a Wix XP filter. How bad is it? I need a sanity check.
Previous oil was M1 AFE 0W30, PPE is quieter for now.

2017 Pacifica
3.6L Pentastar
~104,000 miles currently

Brief history: I have used PP0w20 at OLM intervals (approx 10k) since we got it at around 40/45k. Past life was a rental iirc. Over the last several oil changes, It would use 1qt/5000 miles

Don't remember exactly why I made the change. I think I was kicking around switching from PP 0w20 to HPL 0w20 or 5w20 to see if it would clean up the oil consumption (a stretch I know, but why not experiment when it won't hurt anything). I know I went with 0w20 over 5w20 to not make too many changes at once. So it was just an oil type change, not a viscosity grade change.

Probably wanted to cheap out a little because the van doesn't get driven much anymore as my wife and I work together and we drive my truck most days and my truck is the family vehicle. When it does get driven, it's a decent highway drive.

Sitting right around 50% on the OLM, it's at 5 months and about 5000 miles (guessing, no I don't keep detailed records for my wife's car) in where it should have used a qt of oil and its currently sitting no more than 1/4qt low. I checked it at the gas station yesterday, not my official oil level checking location.

I was not expecting this much reduction. I'm impressed.

'18 Grand Caravan @ ~120K currently, regularly burns about 1.5 qts. over 8-10,000 mi. between OCI's with mostly Valvoline synthetic. Oil filter housing just started seeping over the last OCI. :(
 
As stated earlier I’m going to run ESP 0w30 as I do in the rest of my fleet. What oil filters do you guys like?

Obvious top contenders for me are Premium Guard/CQP/Microgard Select. It will be really nice inspecting the cartridge filter before installation!

CarQuest Premium seems to be a safe choice, at the moment. The Mopar filters are well made as well.
