Jaguar XFR Oil

M2C945-A replaced the spec you’re referencing. M2C945-A can be used safely with no issues.
AMSOIL recommends their Signature Series 5w20 for your car. It’s an excellent oil. I don’t know who you talked with at Jaguar, but specifications get updated. I would take their advice with a big grain of salt.
It's pretty well known. They only recommend one spec for the 5/0L engines and only they sell it. Nothing meets the WSS-M2C925-A spec.
I think you're misunderstanding. I 945-A replaced 925-A and is a perfectly suitable substitute for your engine.
If it was mine, I think I'd just pick up M1 FS 0w40 or Castrol's equivalent and run with it.
And you don’t see a conflict of interest in that?
“we are the only ones selling a suitable oil”...
Was it the parts guy selling the oil who told you that?
Of course but this has been known for many years. It's not one parts guy.
You might find these discussions of interest:
Manual calls for oil meeting “Ford WSS-M2C925-A”
My owner’s manual calls for oil meeting “Ford WSS-M2C925-A”. This standard is pretty obsolete and finding oil that meets it is difficult. Is there anything special about that standard? Or can I safely use oils meeting other, more common standards like the Ford WSS-M2C945-A? I don’t want to harm...

Difference between Ford M2C925-A and M2C930-A
I'm lucky enough to run one of the new 5L Jaguar V8s which (according to the manual) have only one recommended oil: Castrol SLX Professional Fuel Saver A1 5W-20 (meeting Ford WSS-M2C925A) This is extremely difficult to get hold of in the UK, and even the dealer seems to have problems getting...

WSS-M2C925-A is simply a spec requiring a full synthetic.
car runs pretty hot makes a lot of power, just use 0w40. only other blown car i know that calls for 5w20 was the terminator.
JLR was unfortunately leaving Ford around this time so they also started transitioning away from their specs. If you want the official stuff whatever they want for a 2020 F-Type R should work, the engine has been the same for like 10 years.
I’ve heard the water pumps on these are pretty garbage, make sure you get that fixed.

The spec does not mention anything about base oil type or requirement. It is a pretty old spec requiring a 5W-20 based off of ACEA A1/B1 but with some additional Ford-specific test requirements (oxidation stability, fuel economy). It is likely that only a synthetic will meet the performance demands but it isn't mandated. The 945-A spec is a 5W-20 based on ILSAC GF-5, so different. JLR spec STJLR.03.5004 replaced Ford 925-A (JLR have introduced their own specs to undo reliance on heritage Ford specs from their time as part of PAG).
Thanks Weasley, I was hoping someone in the know like you would help out.
If I recall A1/B1 is no longer a current ACEA spec, so what should the OP look for as a good starting oil. A full synthetic A5/B5 in 5W20 or 0W20?
^ Looking closer at the new ACEA sequences, maybe a C5 oil is the place to start looking for 20 grade synthetics.
A 2016 C5 oil is required to leave less piston deposits, have less oxidative thickening, and produce slightly better fuel economy compared to a 2010 A1/B1 oil. But with the same wear requirements. According to the Lubrizol spider graphs

OP, just googled around based on Weasley’s knowledge that STJLR.03.5004 replaced Ford 925-A and I found a Valvoline SynPower 5W20 FE
It claims “SAE 5W-20, API SN, ACEA C5, FORD WSS-M2C948-B, Jaguar Land Rover STJLR.03.5004”
and “Suitable for use in petrol, diesel and LPG engines where SAE 5W-20 ACEA C5 (previously A1/B1) specification is required.
Especially recommended for Ford petrol engines demanding a Ford WSS-M2C948- B specification and is backwards compatible with WSS-M2C913-B motor oils, as well as WSS-M2C925-B.”
I believe M2C925-B was the updated 925-A, which is what you want.

SynPower FE 5W-20 - Full Synthetic Engine Oil | Valvoline
SynPower FE 5W-20 is specially developed for Ford’s ultra-economic Eco Boost engine line.
Fuchs also has one,
Looks like VSP FE could be a good choice. ACEA A5/B5 is another (Mobil1).
Thats interesting. My Mondeo ST220 specifies WSS-M2C913B oil. Officially, WSS-M2C913C and WSS-M2C913D oils are the secessors and fully backwards compatible. However, despite the owners manual calling for a WSS-M2C913B oil or a 5W30 A1/B1 oil all the oil websites when you search for the car suggest 5w20 oils. I wonder if this is why?
I would stick to the 913-D oil, it’s one of my favourites. It starts out as a thin 5W30 A5/B5 oil with extra TBN added for long OCI and extra ZDDP added for the Ford timing chain wear test.
To be honest, it’s probably what I would run in the Jag too.
