When you consider the Amsoil guarantee, their synthetic is not expensive unless you ignore their warranty, 25,000 miles for their normal synthetic and 35,000 miles for series 2000. Amsoil is the original synthetic oil manufacturer, back in the 80's when
all other motor oil producers were nay sayers about synthetics. Now all of them have joined the synthetic crowd, but none (NONE) meet the specifications of Amsoil. Mikey does not know what he's talking about. Check the 9 different recognized ASTM tests that all motor oils are subjected to and you'll find Amsoil is the best available and guaranteed too. See http://oilspecialist.com/motor-oil-t...l-testing.html

I'll chime in to agree with Brutal that manufacturers don't seem to care what kind of oil is used.
My experience in 30 years at dealerships, FWIW, is that warranty coverage on engine failures is seldom denied and occurs only when there is absolutely iron clad, beyond-any-dispute evidence of neglect or abuse. I can never recall the brand of oil coming into question.
I'm referring here to the original factory warranty coverage. Many service contract ("extended warranty") companies take a harder look at such things ....and there are a few stinkers who will overtly and totally without shame dig for any reason to deny a claim. Even then, the *brand* of oil would likely be too far of a reach.

Looks like this thread is going the way of oil threads.
That site's Amsoil's (isn't it?) so hardly unbiased.
To the OP: for goodness sake don't leave the oil in for 25K miles let alone 35K. Any reasonable make of oil will do that meets the jag spec, and there are lots that do.

My final put on the subject- Amsoil is the subject of much controversy and contradictory misinformation, not much different than my other favourite miracle in box- K&N filters. I got yet another PM over the warranty subject and reread the link I was given. If credible, it states that Amsoil will go to bat for owners who have warranty cases denied due to lack of API certification. Doesn't say that they'll pick up the tab, just that you'll have their support. Whoopee.
So, again I ask the question- given the lack of API certification, questionable warranty coverage, high purchase cost and most importantly absence of evidence that it has any real world benefits in our cars, why would a reasonable person choose such a product?
Take jagv8's advice (bolded above) if you don't like mine.

Answering just for myself but when I buy premium products like that I do it because it feels good :-). I also prefer genuine Jaguar oil filters, belts, etc. for the same reason. I just like to do it. I have no illusions or delusions about the real world benefits of doing so.
Eons (seemingly) ago when I bought my first Jag I was insistant, for instance, on using Castrol GTX oil. That's what you used in an old Jag. That's what *everybody* used in an old Jag. Tradition. Loyalty. Faithfulness. Jaguar and Castrol are like toast and butter, after all.
These days, however, my pocketbook is influencing how good I feel. Whatever name brand is on sale that day makes me feel pretty good. Not "Castrol good", mind you....but pretty good nevertheless :-). I dream of the day....probably when I finally get my youngest out of college...that I can feel "Castrol good" again.

I think you need to understand the relationship between Castrol and Jaguar. They signed an agreement that had Jaguar specifying only Castrol products. This has/had nothing to do with testing or performance at all. It was just a business deal. See the attached document. It is a factory TSB.

I think you need to understand that the Jaguar/Castrol relationship precedes, by decades, your linked document from 2004 :-). Perhaps there were previous business deals ? In any case, the relationship is long standing, be it business (for them) or merely sentimental (for us).
Also, I think you need to understand that I never claimed the Castrol/Jaguar relationship had anything to do with testing or performance....although I certainly appreciate you taking the time to advise me that I need to understand because, being so dopey and all, I probably would never know :-)
Lastly, and since we're advising each other on what we think the other guy "needs to understand", my posting was intended to be light hearted, satirical, and self-mocking in nature, which is something I think you need to understand. I would've thought the smilies and general tone would've done the trick but, alas, I clearly failed...sigh :-)

My spidey senses were tingling...now i know why! LoL.
Plenty of good advice and related info/links...but any thread with 'oil' as a topic gets taken on every tangent it seems. The OP got his question answered, so how about closing this down I liked the humor n sarcasm from a few of you also, enjoyable to read.

I dont know let's ask......... actually if you new how many gear heads are in Jaguar.....Jaguar set up a ride and drive with us last year. we got to race on the track(road course south of Houston) then were taken for a RIDE with pro drivers. Those cars were totally brutalized and handled it great!!!

Yes, as predicted it's going off the rails. I see people are whipping out their favourite websites to defend it's honour.
