I found the 5 W 20 Castrol SLX oil for sales at Prestige Land Rover in Paramus, NJ - $15.95

 

You can purchase it thru any Jaguar or Land Rover dealer. You can go to either Bedford or Exeter NH.

 

Why are youl looking for European blend oil we have Ford motors. I'm just curious of why you just don't buy Castrol Edge oil?

 

It is the only oil Jaguar recommends for the 5.0 liter engine.

 

If you use anything other than the castrol slx....will your warranty be voided?

 

The answer is no it doesn't void your warranty if you use a different oil that meets the standards, it can if you use an inferior oil, but might be hard to justify. But the book only says you can use any oil that meets the WSS standard which is a Ford standard and simply states it recommends Castro.

 

Mobil 1 meets the Standard and so does AMSoil so those are fine, if you are going to go with either of those, I would recommend the extended blend of those oils so you can keep the 1 year intervals.

 

Thanks for the info. Your statement is consistent with what I have been hearing. Thanks again

 

Last summer when the Jaguar dealer changed my oil, they used Amsoil. They said they normally use Castrol SLX Professional, but when they run out, they use Amsoil.

 

I just use Mobil 1 5W-20 Extended Performance. Half the price, and a better oil -- both from a qualification standpoint and from the results of oil analysis over extended drain durations.

 

do you bring the oil to the Jaguar dealership, or do you take your car somewhere else?

 

Dealership labor is way too much...

I bring the oil & filter to my local mechanic who does it for $20.

Mobil1 5W20 Extended Performance $8.20 x 8 quarts + Jaguar OE Oil Filter $23 + Jaguar OE Air Filter (set of 2) $46 + $20 for labor = $154.60 + your local government rip off in taxes

That's about $120 less than the dealership wants for the 15,000 mile service.

 

How come you haven't bought K&N filters. you can go 100,000 miles before they need to be cleaned. I got a set for $66 and put them in myself. If you're paying $46 every year, even if you pay $100 for a set, they will more than pay for themselves within the life of your car.

 

I don't like oiled filters. I don't like them for three reasons...

(1) While they flow better when new, they clog whose when dirty than paper elements, so you are more prone to flow variances over an installed duration.

(2) I'll rather replace than remove, clean and re-oil the K&Ns (the oiling kit is $10), in large part because it is hard to get them really clean even when you use a detergent.

(3) Oiled filters have a tendency to mess up some air flow meters by leaving a thin film of oil of the hot wire which then cokes during the self-clean cycle and insulate the wire slightly causing reading discrepancies.

Despite the slight flow advantage, I never use oiled filters in any of my cars. Maybe there is a reason OE filters are never oiled filters. It's also rubbish that they don't need to be cleaned for 100,000 miles. The dust and dirt that makes it into your intake has to go somewhere. It either goes straight into the engine -- in which case the filter isn't working, or it gets trapped by the filter which overtime clogs it. The amount of gunk the filter must trap is the same in the same driving environment regardless of your filter choice. K&Ns get clogged just like everything else. You should remove them at the same intervals as you'll change paper filters. The difference is that instead of throwing them away, you wash them good with detergent and warm water to get as much of the gunk out as you can. The filter is close to white afterwards. You re-oil it with the K&N flter oil which gives it the reddish hue. The key though is NOT to over oil it. over oiling can cause oil vapor to get sucked past the air flow meter and screw it up. You must also not under oil it as the cotton element is very porous and relis on the oil to attract and trap dirt. Under oil it and the filter doesn't work well to keep **** from getting into your engine.

 

I am not trying to pick a fight here, but if I was arguing with the Jag dealer about my engine meltdown with my 100,000 mile extended warranty, i would prefer to have oil in it that "meets the requirements of M2C925A" rather than "suitable for use".

I personally do not like Castrol, nor do I like marketing entanglements, BUT the manual and the document I was given at delivery were very clear, M2C925AA.

Other opinions vary.

 

WSS-M2C925A is a Ford engine lubricant specification. Jaguar used Ford specifications because it used to be part of Ford's Premier Automotive Group before it was sold to Tata Motors. The 5.0 AJ133 engines were developed back then.

In any case, WSS-M2C925A was superseded by WSS-M2C945A in all Ford "Motorcraft" products. In other words, all the M2C945A oils meets and exceeds M2C925A.

 

dwight:
While most of what you said is presumably 100% true, it does not mean that the Mobil 1 "meets the requirements of WSS-M2C925A". It may exceed the performance level, but the Jaguar manual does not say that the oil needs to be "suitable for use", it says "meet the requirements."

Obviously, you have made up your mind, so go for it. I doubt you will have ever have any trouble from your decision. I might even follow the same course!

BUT: Others who wish to forego a potential argment and legal fight with the dealer may want to look here:
Mobil 1 5W-20

Mobil themselves distinguish between "meets the requirements" and "suitable for use".
