Hi All,
I have been directed to this thread by hlgeorge.
In answer to the original question we would recommend synthetic oil. For all other other specifications and requirements please see below:
V6 Petrol Engine
SAE 5W-30 engine oil meeting Jaguar specification
WSS M2C913-C is preferred. Oil meeting ACEA A1/B1 or
ACEA A3/B3 specification may be used.
V8 Petrol Engine
SAE 5W-20 engine oil meeting Jaguar specification
WSS M2C925-A only.
Diesel Engine
SAE 5W-30 engine oil meeting Jaguar specification
WSS M2C934-B only.
Many Thanks

Hello,
Thank you for your post.
If you use incorrect oil in your vehicle and a warrantable item goes that has been caused as a direct result of incorrect oil being used then that part of your warranty becomes void.
Please refer to your handbook for full warranty information along with the oil specification.
Many Thanks

So Mike, you are stating that it is Jaguar's official (and therefore legal) position that if I use a SAE spec 5W 20 synthetic oil in my 2009 XF-SC that is not WSS M2C934-B "only" that my engine warranty is null and void? With all due respect, you may want to check with your legal department before answering this.

Since Mike has previously posted that he is a representative from Jaguar Customer Service, it is more than likely that the information is copied and pasted from an official Jaguar document.
You have tried to buttress your claim despite good information to the contrary. Now, there is a response from a Jaguar representative and you are still clinging to your position.
If you want a legally binding response from Jaguar, then the proper thing to do is to contact Jaguar Customer Service directly. Trying to get a judge to accept a posting on a public forum as legally binding would not be easy. In any event, you will probably be referred to the exact same wording.
edit:
In the interim, Mike has responded with his advice to consult your handbook. That should end the matter.

As far as I can see the US legislation simply requires the manufacturer to prove the failed component did so because the specified oil was not used. Therefore a failed wheel bearing could not be blamed on use of the wrong engine oil. However, if Jaguar requires you to use oil meeting a certain defined specification ( in this case a Ford Motor Company specification) and you do not AND Jaguar can show the failure was caused by or contributed to by this use of incorrect oil then indeed your warranty is void with respect to that failure. The wheel bearing still gets fixed for free though.
This is not the case outside the US where the usual rules of proof apply, if warranty coverage is denied outside the US market then the customer must prove breach of warranty.
Thankfully, it has been my experience with reputable manufacturers, including Jaguar, that such technical positions are rarely adopted. However, to maximize the voluntary factory goodwill factor it is wise to ensure that ALL service during warranty period is performed by a dealer or approved independent where dealership service is not available AND that ONLY OEM factory supplied or approved parts are used. This makes it easy for Jaguar to be confident the warranty failure is covered without an expensive investigation and risk of a poor customer relations outcome.
Using only the warranty specified service is a small price to pay for a good relationship with Jaguar should any warranty issue arise. Once the warranty expires you can do what you wish. However, it has been known for Jaguar, among others, to informally extend some after warranty repairs as long as the car had been completely dealer serviced for your entire ownership. This is entirely voluntary on the part of any manufacturer and prompted by development and maintenance of good customer relations as well as an acknowledgment that errors sometimes occur and customer feedback is vital for future improvement of Jaguar cars.

Very good response Jagular. I had asked Mike@Jaguar to respond, but I realize he is also under restraints from Jaguar as to how he can respond to this question. I am sure that the outcome of a warranty issue concerning oil usage would be on a case-by-case decision from Jaguar. I believe that this is the only real answer that can be stated without an individual case to look at.

Does anyone on this thread know if I can use a full synthetic oil, like Mobil 1, that does not meet the "Ford WSS-M2C925A" standard? I am not concerned about the warranty (out of coverage), but I am concerned about the health of my engine? Is there something special about the Castrol Professional OE that my 3L V6 SC MUST have? Any help is appreciated.

Any chance we could consolidate all these oil threads into one single active thread? Maybe a mod could close the other ones so only one is active?
It’s a good discussion but really hard to follow across 7 different threads and there are a lot of contradictory posts in the threads.
I know we have a couple of Jag authorized mechanics on here. I’d like to hear their take on what the official Jag guidance is - and what dealers do in practice if different

Dear Car Talk:
My reason for writing is that all these alphanumeric algorithmic specifications on oil these days are confusing me. I have a 2009 Jaguar XF with a 4.2-liter engine. I've owned many older Jags, but this is the first one that states I need WSS M2C913-B, which I learned is a Ford part number. But I can't find it anywhere. What oil would be safe to use in this car now?
-- Michael
Well, you've fallen into an unusual automotive black hole, Michael.
Ford owned Jaguar until 2008. Then the great recession hit, and Ford sold everything it could spare except old pairs of Henry Ford's boxer shorts. So the 2009 Jaguars were basically designed by Ford but sold by Jaguar (which was, by then, owned by the Indian conglomerate Tata).
So if you ask Jaguar for part number WSS M2C913-B, they'll tell you to go ask Ford. And if you ask Ford, they'll tell you that the 2009 Jaguar is not their problem, go ask Jaguar.
But not to worry, Michael. WSS M2C913-B is actually a Ford of Europe part number, which is why you can't find it at your local Ford dealership.
The best I can tell, it's basically a fully synthetic 5W-30* oil. And since oil specifications tend to improve over time, I think you're completely safe using any of the brand-name synthetic oils available here in the States. So a 5W-30* version of Castrol Edge or Mobil 1, to cite two examples, should be entirely safe for your Jaguar.
And it should be cheaper than flying to England once a year and coming back with a case of WSS M2C913-B in the overhead bin.

*That was the current spec then. It may have changed now. The new ILSAC GF-6 and API SP specifications for passenger car motor oil launched in 2020,.
These new, higher performance oil categories have been developed in response to several driving forces. The most important factors include need to improve fuel economy and reduce greenhouse gas emissions as well as the increasing demands of modern engine technologies.
