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.

 

Wishful thinking. 945A did NOT supersede 925A. The specs are different.

 

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

 

Of course. Thank you for taking an interest. I drive a 2013 XF 3.0 (V6 SC).

 

You are in the wrong forum. You should be in the XF Forum where you will get better answers to your question. This is the XK Forum. Perhaps one of the moderators will move you to the correct forum.

 

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...

 

I looked at the two Product Data Sheets published by Castrol for Edge Extended Performance, and neither list compliance to Ford WSS-M2C925A:

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:

dpresent,

I have moved your thread from the forum for the X150 to the forum for the X250, which is the Jaguar factory project code for your 2013 XF. Here you will find knowledgeable owners of similar cars.

Cheers,

Don

 

This is helpful, thank you! (even though I'm on the wrong forum...oops)

 

Uh oh... the OP DOES own an X150, and posted in the correct forum.

 

Someone has lost the plot.

 

I returned the original thread to the X150 forum and left the posts germane to dpresent's question here in the X250 forum. Let me know if I've overlooked any other complications!

Cheers,

Don

 

Wow, if this is true, I'm in heaven! Just got my 2010 XKR without any pre-knowledge of the strictest of oil specs and scarcity of that spec oil, so in my area I would have to drive 50 plus miles just hoping the only local jag dealer has the right oil (they sounded confused when I called to ask). The 0W-50 and 5W-50 Castrol Edge Extended Performance is readily available but other posts champion the Edge Professional as the only correct choice. Either way, I'll do what's necessary to best protect the engine but hope the option you raise is real. I couldn't find your post with the Jaguar Corporate reply, could you point me in the right direction? Thanks. Never had these kind of issues with my XJS 6L.

 

I also would like to see the jaguar reply . i have only used 5 w 20 in mine with no problems

 

Ditto.
In both my XFR and F-Type.

 

In years of reading i can honestly say i have only ever read about engine problems when owners have used the 0 w 20 and not the 5 w 20 makes you wonder

 

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.

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.
