Does the engine covers just pop up by pulling? Thanks for the help.

Just tried it on my XF and the cover pops up when lifting the front, then has to be slid forward to free it from two rubber grommet in the back. The filter housing is indeed where you indicated and the funny part is that it has FoMoCo (Ford Motor Company) label on it.

 

Not a problem.

I am not sure on the cover, but sounds like you got it off. Great!!!

Supposedly, Jaguar has contract with Ford to provide them with engines till 2016. You will probably notice lot of parts with FoMoCo stamped on it under there.

Although, i have also heard the engine is designed by Jaguar and built by Ford in Germany.

I don't know who makes what any more, but seems like collaboration is the only way to survival.

 

Looks like the XK cover comes off in the same way - pull up at the front, then slide forward.

 

The answer to the original question- why this oil. For those who may still need answer.
Two very important reasons.
1. The radical 5.0 engine design poses some serious challenges to oil. The passages are narrow, pressures and temps are high, and buildup potential is great. In other words, if this oil did not exist, this engine would be designed quite different. Now realize why the pressure is greater than other engines: One of the greatest new technologies to emerge in the automotive world is the CTA cam timing- A Jaguar innovation licensed by Ford!!! Its a Game changer because it increased power, response and efficiency. It relies on higher oil pressure to do the trick. Castrol formulated an oil that would help pull them off. Do you think that its any coincidence Ford also has the same mandatory requirement. Heck, you could use vegetable oil in the other ford engines.

2. Jaguar has been on a secret mission to be in the top 3 of reliability ratings. This oil helped there, it can be punished for a full year under the conditions above. And the results have spoken for themselves, the Germans are plagued with premature carbon buildup on the Direct Injection engines. As is Ford BTW on the non Jaguar design engines. But not Jaguar.

For F sake, use this oil its actually less money than the mobil1 junk because you would have to change it 3 times in that same interval.

 

P.S.
I think there might be some truth to Jaguar being an old penny-pinchers auto. If this was a M3 or a rice rocket, they would never second guess the recommendations, even for the washer fluid.

 

HELP! I know old thread but maybe anyone could chime in please on this!!, I have the 2011 XJL 5.0 Non Turbo and am hearing from most places including manual to only use Castrol 5W-20 Synthetic WSS M2C925-A. I looked at all the Castrols on the shelf and the only numbers I see on all their brands is WSS M2C945-A, not 25 but 45. Should I just use the 45 because it's close enough or can just put in my traditional Mobil-1 5W-20 in??..I only put 2000 miles a year on it so I doubt it's gonna hurt much I'm thinking to substitute...Hmmmmmmmmm

 

 

This particular Liqui-Moly oil also meets JLR specs for the 5.0L engines, and costs less than the Ravenol or the OEM-recommended Castrol.

Because the OEM-recommended Castrol is virtually impossible to buy outside of a JLR dealer, a clever Forum member gave it the nickname of "Unobtainium". The only reason to use that Castrol is if you're still under factory warranty. It contains a special dye that, if not visible, makes it easy for Jaguar to deny a warranty claim and put the burden of proof on the owner. That dye is not part of the SAE oil performance specifications.

 

Careful with this one.
The only reason to use the factory Castrol is its proven in our engines over millions of miles with no problems attributed to the oil.
The oil I use, or any other cannot offer this assurance on this engine.
But I chose to take the risk. I'd want the other person to know that its a decision they have to make, and not one that's been decided.

 

I would expect identical performance from fully synthetic motor oils from different manufacturers that meet the same specification. With identical specs, the only real difference is the price and brand name. Is Ravenol or Castrol worth double or triple the cost (or more) of Liqui-Moly? The answer depends on the buyer's subjective perception and value placed on a brand name. Your money, your car, your choice.

Just be sure to use the proper spec oil.

 

"... factory Castrol is its proven in our engines over millions of miles with no problems attributed to the oil" is just marketing hype. The 5.0L engine is not immune from lubrication problems. They're just not publicized.

I'd pay the premium and use my dealer and Castrol if they put their money where their mouth is. Give me a written promise to repair or replace my engine at no cost to me if it fails due to excessive wear or inadequate lubrication and I'll be a Castrol customer for life.

 

Here's the proof that Castrol's claim is marketing hype.

Jaguar changed the viscosity specification (I think it was in 2016) from 5W-20 to 0W-20 because of premature engine wear, specifically the hydraulic chain tensioner and guides. Using thinner oil at startup was to improve flow and reduce wear. Read this thread from the X351 (XJ) Forum:
https://www.jaguarforums.com/forum/x...t-done-214277/

 

Bought 8l of castrol pro edge A1 5w20 and oil filter today as well as engine oil flush . Normal cost per litre £17.50 got it for £10.00 per litre , Eurocarparts sale . car was serviced 3000 miles ago B service . will do job later next week once i get the time .

 

My dealer charges $7.65 a quart for the Castrol 0-20W called for. Only thing is that I need to bring in a couple of old 5 qt oil jugs to put it in from their 55 gallon drum.

 

You lucky dawg lol my local dealer is dick turpin

 

My dealer is Bobby Rahal and he even shows up occasionally. Just have to remember not to mention female Indy car drivers.

 

Exactly.... Cause if you are out of warranty, no Jag dealer is going to make that promise! So sticking with an over inflated dealership price per oil change is just tossing cash into the toilet!

Lots of great oils out there to choose from that exceed Jags specifications.

 

Can I add on to Bri's Jag's original question. Looking at the Castrol website the Edge Extended performance 0W-20 says "Meets Ford WSS-M2C947-A" and I can find nothing from Castrol that meets the original 925-A. So couple of questions.
When JLR changed the recommendation from 5W-20 to 0W-20 did they also change the specs? I notice that almost every product I see has different specs for different viscosity oils.
Does the 947-A exceed 925- A?
I realize that other mfg. produce oil the meet 925-A but I would think that if Castrol remains a "partner" with JLR they would continue to produce an Oil for the cars.

 

The 925 and 947 specs are different blends, and I would use only the 925 spec if my 5.0L engine is still under warranty. Otherwise, the dealer could deny a warranty claim. But does it really make any difference? Your car, your money, your choice. Read this entire thread and note Brutal's comment.

P.S. The reason for the change from 5W-20 to 0W-20 was to remedy premature wear to the hydraulic chain tensioners at startup. Read this entire thread:

(emotional disclosure, I dont use Castrol, because technically no one sells it, not even dealerships, those who do are going out of their way)

Lots of misinformation, when a casual joke is being taken as prophecy because it fits a confirmation bias.

Castrol does not give free oil to Jaguar. It would make no business sense to promote oil that is not sold anywhere.
They probably gave Jaguar free technical support to develop a blend for them. Which would make a lot of business sense.

I would not use Castrol not blended for Jag, there is a massive difference in blends, that dont show on paper but they do in testing.
