From a logic perspective, that's about as logical as saying, "you start a car by placing the key in the ignition, and by turning the key you engage the starter, ipso facto, or by reason thereof, ground cheese tastes great on pizza." Its a logical non-sequitur. The AJ33 has been used for years, in various models, in various years, on the same line in the same assembly facility. From an engine oil perspective, Jaguar has always advocated the latest technologies in advancements, even to the point of working with Castrol to develop specific additives to help extend engine life, performance and reliability. If anyone is stuck in the 70's, when it comes to lubricants, sadly it is you.

I don't have Box's experience, but I doubt that remark will go unchallenged.

First time I ever heard of a Jag owner foregoing warranty rights by deciding they knew better than Jag.

Who exactly do you have in mind? No one here has suggested that the Castrol 5-30 spec is hogwash, only that same-spec synth oils are superior.

I understood that the suggested direction was 'present some new info'.

Other than endlessly repeating yourself that 'newer spec oils are better so therefore owners will reap the benefits' to my challenge 'then show me the actual benefits, not just theory and lab results', do you have anything new?

The evidence is out there. From years of race proven results, to fleet records, to manufacturers testing and recommendations, to industry standards testing results. Go do your own homework.

We're talking about 'Jaguar S-types' and not presuming that whatever might be true on other engines in other applications is inherently applicable.

These were the standards used to condemn Jag for the 'sealed for lifetime' blunder.

I guess your modes operandi is if you throw enough crap on the wall, then maybe some of it will eventually stick. Jaguar specified their recommendations then, and it is still their recommendation now. In fact, they state, "Jaguar exclusively recommends Castrol EDGE Professional oil, engineered to perfectly complement our engines and optimise performance. Castrol EDGE Professional is stocked by Jaguar dealers." And, "In Castrol’s variable speed Fluid Strength Test, Castrol EDGE Professional boosted with TITANIUM FST™ gave up to 45% less metal-to-metal contact than a major lubricant competitor’s product. Products representing 61% of our 2012 sales volume were tested."

To which you replied:


I'll take the statement above as no, I'll just keep repeating the same old thing.

Thanks, you've answered my question.

I'm still waiting for you to either admit you lied to us, or provide the Zone rep name and number. Figure it out Mikey.

Box , before you start calling anyone a liar , is possible that the zone rep wishes to not have his name and number splashed all over this forum , I know I wouldn't , and if that is the case , then I respect Mikeys decision not to .

Have a good day ,

I've just done the oil and filter change on mine and it used just under 7 litres.
About 1/4 of a litre left over.
I bought 7 litres of Comma Xtech Fully Synthetic 5w30 and a Coopers FIAAM filter
incl VAT £43-00
Might want to buy 8 litres so you have some top up oil.

The purpose of Zone reps from the manufacturer, is multi-faceted, and I can tell you that is part of the job. See, it isn't the lie that bothers me, it is the insult to my intelligence that I find offensive. Everything that Mikey has asserted is just plain ignorance. (no knowledge) The reports of self-styled want-to-be experts, who have no real idea as to what they are saying is analogous to a blind man from birth standing in the shade of a rock cleft screaming at the top of his lungs "the sun never shines!" when you have awakened daily and watched the sun rise and fall. It's kind of silly to listen to that blind man don't you think?

I know what a Zone rep would say to a customer. I worked for over a decade at one of the Big 3, I've seen destructive testing on thousands of engines, I've seen 10's of thousands of vehicles under warrantee claims, I was the Midwest Regional Training Manager for Sun Electric for over 5 years, training techs at Chrysler, Ford, GM, Toyota, Subaru and countless independent shops. I'm a certified ASE Master Tech. and in a court of law would be considered expert testimony. I can tell when someone has zero expertise in the industry. It's not rocket surgery.

I have got it figured out.

You have no evidence whatsoever to back up your multiple claims about the latest generations of oils making engines in S-types last longer. None. Zero. That was obvious from just about the first post.

As to the name and phone number of the zone rep, that's been a nice bob and weave technique to avoid discussing the subject matter. I did answer your question way up above with some critical information that either you missed or possibly didn't understand. It correlates information provided by several other posters here regarding the history of the cars and their service life and blows every bit of your argument out of the water.

You've made several claims regarding how the auto industry works that I know to be factually incorrect. I've verified them with some contacts who are today regional/zone reps (or higher) working for two of the big 3. I know that at least one of them is watching this thread.

If there's somebody who's not been honest here, it's not me.

We are not going to degenerate into mudslinging, if you want to discuss oil go for it if not there is no benefit in this thread continuing.

This on it's face is absurd Mikey. If two people, without any experience in a given field, agree on a given item, it doesn't make them both right. That's like saying if 4 people on this board agree that black holes don't exist, then they don't exist in your book. Have fun telling yourself that. Now concerning your contact with Jaguar representatives, as you stated, either provide the contact information, or don't assert it. Accuracy is more important than your ego's desire to be seen as right.

Thanks for trying.
