Stellantis MS-A0921

Be interesting if this appears on M1 ESP 0w-40 in the next little bit (I don't expect this oil to share certs with M1 FS 0w-40).

I don't see SAPS content listed in any discussion of this approval specification. I think it would be a very important aspect of the discussion since 0W40 is a viscosity primarily used by European brands where oils always also get ACEA certifications. Based off what I see from oil manufactures who have approval and those who say their oil is recommended for the specification, any recommended oil for the HEMI engines where these specs are called for MS-A0921, MS-12633, MS-10850, MS-10725 are all high SAPS content oil suggesting the SAPS content is needed to protect the valvetrain. M1 ESP 0W40 is an oil designed to protect gasoline particulate filters therefore is has a lower SAPS content and would probably never meet approval standards for these cars. I'm super curious about the SAPS content of the PUP 0W40 that is SRT branded. This oil could possibly be an ultra-high SAPS content motor oil but I'm not sure how one would go about figuring out that information.

The SRT oil is low SAPS, it has regular API RC compliant levels of phosphorous, even though the 40 grade omits it from those requirements.

Would sure be sweet if some 5W40 oils on the shelf would be a good fit for these 6.4 Hemi engines. 5W40 options are so much easier to find.

Any Euro 5W-40 would be suitable.

Looks like they are saying API SP is a higher standard than Chrysler MS-12633.

or just that part of the MS-12633 spec is to meet API SP standards....

There are several VOA's of it.
