Official EcoDiesel Oil and Filter Recommendations

[Hootbro]

I read it more like they claim it meets those requirements. Who is the decision maker?

I hate the world we live in where you have to question everything because so much is deception.

Verbiage is everything and I read it the same way as you. Castrol is basically self certifying they "meet" the MS-12991 vs. stating they carry the "Approvals" which signifies it has actually gone through a certification test as administered by FCA/Stellantis.

This really is not unique to Castrol as about all the major oil brands do it but may express it with statements like "suitable for .......", "meets" and "acceptable" . These are monikers to mean that from their perspective they meet the technical intent of whatever spec they are using it on, just they have not completed the certification process and obtained the "Approvals" from the entity defining the spec.

I am pretty familiar with the MS-6395 spec and certification process for the gas engine oils. The technical chemical and material to formulate is not really that unique and super special. The sticking point to many oil companies getting "approvals" out the gate for the oil is the performance requirement that the oils are run through a special Chrysler Las Vegas taxi fleet for 100K miles across two summers and one winter. At it's fastest, that is a two year process to get "approvals" and companies like Castrol will either forgo that part and stick with the "meets" type language or just use the same language selling the product while they wait out the process to get the approvals.

I cannot find any data on what the MS-12991 entails for true approval process, but I suspect it is probably a similar process.

Ya, I've got some drugstore mineral oil with a cool blue coloring and a flashy bottle with a pour spout that I self certified meet "xyz" requirements for half the price of that expensive Mopar 5w40 fluid........wanna buy some? Better yet, I marketed it as 10x better than xyz requirement and its twice the price........wanna try some of that?

Kind of like Penzoils Super Duper oils, Nothing on their bottle says they are "Approved"?
Their labels states that it is formulated to meet or exceed the MS12991, nothing about whether it does or not.

This was brought up on the Wrangler side, but in the 2022 model year it looks like Jeep has updated their owners manual to be less stringent for oil requirements. This has seemed to cause a lot of confusion regarding if the MS-12991 is required or not. It's not - its "recommended" starting 2022. Any equivalent API SN or SP rated oil can be used (SP is latest and greatest introduced in 2020).

Wrangler: 21_JL_OM_EN_USC (mopar.com)

Page 319: Engine Oil Selection — Diesel Engine For best performance and maximum protection under all types of operating conditions, FCA recommends engine oils that meet the requirements of the manufacturer Material Standard MS-12991, and that are API SN certified and meet the requirements of the manufacturer

Page 374: We recommend you use 5W-40 synthetic engine oil such as Mopar® that meets the manufacturer Material Standard MS-12991 and the API SN engine oil category is required

Vs Gladiator 22_JT_OM_EN_USC (mopar.com)

Page 342: does not differentiate between gas and diesel. Only directs you to page 397 for specs.

Page 397: We recommend using Mopar® API Certified SAE 5W-40 Full Synthetic Engine Oil which meets the requirements of the manufacturer Material Standard MS-12991 and API SN or SP capable. Equivalent full synthetic SAE 5W-40 engine oil can be used but must have the API Donut trademark -> page 342.


Note the last part bolded for 2022 which no longer says "AND".

So in 2021 models we can use something higher quality like Amsoil since it meets/exceeds the requirements, but in a 2022 model you should not because they did not pay for the API donut trademark license to use it on the bottle?

Exactly what I’m putting in tomorrow ?

Recommendation: Do NOT rely solely on this list. Always double check to make sure the following oils are current in meeting factory specifications.

The new 3rd gen (2020+) EcoDiesel has different specs than the 2nd generation (2014 - 2019) engine. The following oils have been known to meet the new MS-12991 and API SN Certification/Standard/Approval. I put them in order based on what I think are more 'commonly known', not based on preference or performance.

Mopar 68524020AA 5W-40 replaces 68231020AA
Pennzoil Platinum Euro 5W-40
Valvoline European Vehicle 5W-40
Quaker State Ultimate Durability EURO 5W-40
Havoline ProDS 5W-40
Castrol Edge Euro Car - 5W-40
FRAM Full Synthetic Euro 5W-40
Amsoil 5W-40 FS Synthetic European (EFM)
Redline Full Synthetic 5W-40
Motul 8100 C-clean 5W-40
Motul 8100 X-cess 5W-40
Motul 8100 X-cess gen2 5W-40
Liqui Moly Leichtlauf High Tech 5W-40
TRIAX Euro LX 5W-40
TRIAX Euro Ultra VX 5W-40
Ravenol VST 5W-40
Total Quartz 9000 5W-40
ELF Evolution 900 SXR 5W-40
ELF Evolution 900 FT 5W-40
AMALIE Elixir Full Synthetic Euro 5W-40
Millers Oil Trident Fully Synthetic 5W-40
Millers Oils XF LONGLIFE 5W-40
MPT Thirty-K True Synthetic High Performance 5W-40
CAM2 Blue Blood Elite Euro 5W-40
FUCHS TITAN Supersyn SAE 5W-40
Lubrication Engineers 5w40 Monolec Ultra Syn Heavy Duty Engine Oil
REPSOL ELITE COSMOS HIGH PERFORMANCE 5W-40

Have been known or commonly known??? Simple, if MS-12991 isn’t on the bottle don’t put it in.

I was recently shopping for gear lube so I also looked to see if some others around has upgraded their packaging or specs. I was crossing my fingers hoping Amsoil was there but it wasn’t listed on the bottles or website.

Amsoil does not list MS-12991…wish it did

 

[CrazyCooter]

Amsoil does not list MS-12991…wish it did

Amsoil tech support says that MS-12991 is an old outdated spec and that EFM 5W-40 exceeds it.

 

[NCJL]

I purchased Amsoil last year sometime for my ED based on their website recommendation for which type. My first Amsoil purchase. Once received, No listing on the bottle to meet MS spec so I emailed them for clarification. The response was basically not going to happen do to cost, nothing about the product meeting/exceeding spec, yet Porsche and Mercedes were listed.
What also got me was the marketing items included with the oil delivery. I remember vitamin brochures with a few other items not related to automotive.
Not an Amsoil fan.

 

[Fishmoore]

The cert is in Spanish so there is probably a loop hole in the warranty that voids everything because it's not meant for US based stuff

In all seriousness, good find

Its in both Spanish and English.

So again that brand appears to not be "approved" probably because they didn't pay the licensing fees, but the manufacturer "claims" it meets it.

FWIW, Amsoil has a adjacent owned company that makes Vitamins. Still a bit weird marketing it with their oil sales though.
