Oil Specification: Was Ford WSS-M2C925A replaced by WSS-M2C945A?
I was reading this threat and saw mention of the Ford WSS-M2C925A oil standard. Was this standard replaced by Ford WSS-M2C945A? Will using an oil that does not specifically meet or exceed that standard damage my engine? Any help is appreciated.

Do you think that using an engine oil which meets the 945A spec but not the 925A spec will damage my engine? I am not under warranty so I am not worried about losing coverage. I just don't want to harm the engine by using a good quality full synthetic that happens not to meet the "Ford WSS-M2C925A" standard.

Hi dpresent,
If you will please provide the year, model and engine details of your Jaguar we will try to offer specific assistance.
Cheers,
Don

Not adding anything new here, other than my vote, but here it is:
- My Jag dealer, who's good, uses Castrol Edge Professional 0W-20.
- I actually wrote to Jaguar (posted their reply to me on another thread), who wrote back that Castrol Edge Extended Performance 0W-20 (more available in stores in the US) is also acceptable.
Long story short, after all the research I've done on these engines I stand by these two "bullet-points":
- if you've got a 2010-newer (5.0l), go with 0W-20. Just do it.
- shorter, 6-month change intervals are more important for these engines. Again, just do it.
So them's my two cents. Over and out...

Its unfortunate that Jaguar specified a lubricant which does not appear to be readily available in the US retail market.
Castrol Edge Professional can be found on eBay, however that also does not seem to comply with 925A:

(Look at the photo which shows compliance with various auto mfr specs.)
Here is an eBay listing for the 5W-20 A1 version of Castrol Edge Professional, I do not see reference to the Ford spec when looking at the photo of the bottle rear label, but it does mention a JLR.03.5004 spec:

I had my XKR-S in for annual service and noticed that the dealer used 0W-20 Castrol EDGE oil instead of the 5W-20 Castrol SLX.
I questioned the change and the dealer told me.
We use only the recommended grade on your vehicle

Anyone else have the type of oil changed??? I am trying to find out from Jaguar if this legit or is the dealer trying to pull a fast one??

European Ford Spec
Jaguar WSS–M2C925–A is a European Ford Specification. Which is why you do not find it here in the states and if you use what considered an API or LSAC equivalent, they do supersede the old ones.
Read more about oil here:
https://www.jaguarforums.com/forum/g...ations-250577/
When I bought my first jaguar or two; oil specifications didn’t really matter that much. They just wanted you to get a good multigrade oil, and they even gave a chart of which grade fit which conditions best. Nowadays, their engines are more specific. Jaguars moved the oil filter to the top of the engine. The cars are engineered for better mileage, therefore require more specivity in oil.
But you can’t be expected to use an oil that was new when your car was manufactured! If gasoline breaks down over time, so does oil. (Otherwise, they wouldn’t recommend oil changes based on mileage and or time!) People may go to a Parts dealer and say they want this certain specification oil and they may be handed some thing and told here it is, but it’s probably an updated spec that supersedes the old one. It’s just human nature to never want to admit you’re wrong. I gleaned as much information from experts as I could, and passed along what I learned to hopefully simplify finding what you need to keep your car running smoothly. There’s no magic. It’s just common sense.
