Mopar warranty issues w/ 0w-40 non FCA MS-12633 certification

[dja4260]

Ram 6.4 hemi, new truck. oil changes every 5k w/ 0w-40 Mobil 1 euro.

Hypothetically...

If I had a warranty issue, would using a non FCA MS-12633 certificatied oil such as 0w-40 Mobil 1 euro be sufficient cause for Mopar to deny a warranty repair?

Thank you!

theoretically yes. we’ve never had a dealer ask us for oil change receipts. more than likely they will look under a valve cover or oil pan to see that the engine is clean and call it a day

Not really. They just check your oil level first and they might even check the logged data on the computer just in case you tried to add oil after the fact to see if before the failure happened it indicated the low oil level message was on and if that isn't an issue they'll usually pull the valve cover to take a picture and send to corporate so they can approve it.

The owner's manual is very clear that you need to run a 0W-40 motor oil that is MS-A0921 certified. If you have a warranty issue they will ask for oil receipts, and they will not like when they see Mobil 1 0W-40 there because it is not MS-A0921 certified. Only Pennzoil makes a specific MS-A0921 certified motor oil. I would not risk it and stick with the recommended motor oil. The OEM is always easier to work with when you use what they recommend. I don't think the slight savings are worth the risk.

I see a lot of “recommends”, not a lot of requirements except an API license. If indeed only Pennzoil markets such an oil as you describe then that’s a pretty good clue it’s a marketing agreement, not any sort of technical requirement.

The owner’s manual excerpt posted above shows the material specification is not a requirement.

says any 0w-40 with API donut may be used.

Mopar has different warranty tiers for dealers - there are base, plus and premium tiers. Certain engines require pre-authorization from FCA's Technical Hotline and as part of the review process, they sometimes ask the dealer to upload copies of oil change records. Also, something under powertrain warranty vs. Mopar extended warranties are handled differently. The game seems to constantly change, so you'll have to decide what level of risk you're comfortable with.

Yes.

So, if @dja4260 has an engine issue, and files a warranty claim with a dealership, and the manufacturer rejects the warranty claim because he did not use the correct and recommended motor oil, with the correct certification, will any of you "experts" pay for his claim?

He is using a recommended oil.

If you want to go down the rabbit hole of “recommends,” Castrol makes a very explicit statement in their Edge 0W-40 A3 PDS regarding this application:

"Warranted by Castrol to be completely suitable for use in vehicles where the following specifications apply: MB 229.3,Chrysler MS-12633 / MS-A0921"
So, Castrol appears to think that Mopar might deny the warranty. Sounds expensive but typically a risk I'm willing to take for myself, not for others naturally.

Precisely. Sounds to me that this has been a legitimate issue at one point. Or, Castrol supplies some large dealer groups or fleet companies with FCA dealers/vehicles so they needed to take a transparent position.

did you miss this? From the owners manual page you posted??

Any "full syn 0w40" with api donut.

This is as much nonsense as when hyundai used to recommend BP gasoline. Recommend isn't required.. so ms-a0921 is not required.

 

[Glenda W.]

Per owners manual the OP is good to go.

A dishonest dealer can attempt to deny warranty for whatever reason they want. Having an oil related failure and the dealer proving an oil caused the failure is essentially zero.

I appreciate the discussion that is taking place but don't see a consensus. I feel like I'm using an equitable, if not better products in regards to engine oil...

With all that said, I'll run PUP and avoid any doubt during the warranty period. Seems silly, but I'd rather be safe than sorry.

That is a very good choice. I just double checked to make sure I am not wrong, right here: https://www.mobil.com/en/lubricants/for-personal-vehicles/our-products/products/mobil-1-fs-0w-40

It appears though that Mobil 1 0W-40 is not MS-12633 certified. The MS-A0921 is an update to the MS-12633 certification, and it is very important for HEMI engines to keep them in good running order and avoid any lifter issues.

I don't think your choice to stay with the recommended oil is silly at all. Mobil has been cheapening their product with every iteration, chasing the almighty dollar, in the name of ever-higher profits. Pennzoil has stayed the course. The Pennzoil SRT 0W-40 is a GTL formulation with extra Boron and Moly, and has stayed the same for like - forever. It's good stuff, I wouldn't hesistate to use it if I had a nice 6.4L HEMI. I would definitively not run Mobil 1 in my HEMI, for sure.

Based on the verbiage posted it seems anything 0w-40 full synthetic api certified oil will meet the requirement. They are only recommending the one with that spec. If it was my vehicle I'd use any 0w-40 that I deemed suitable. However, it's not my vehicle and so my opinion is nothing more than an opinion.
