The tensioner is not the problem. Think of it this way if you installed a chain with perfect tension (I know its an impossibility) and there was no further wear and thus elongation- you could omit the tensioner altogether.
I have 300k on a pushrod engine, and the wear on the chain is astronomical. I have used nothing but the best available synth oil since day one.
If you drive the aj133 200k miles, or ant DI car, you will need new chains, (even if you had 5 tensioners in-between) its guaranteed. Would they grant that claim for tc? who knows, Its their money and their mercy, but more than suggestion to go fly a kite Jaguar or any extended warranty company will offer at that mileage.
Interestingly I haven found any claims denied, and its a max of $5k- so for the one in a million that actually goes through with a claim, the cost to Shell is less than offering those rebates, which also work on the principal that most never bother, yet attracted by it.

Agreed, I was just using the term used by Stuart S and I could have and should have been clearer.
It's the design of the chain guide that is the problem on older AJ133 engines, the metal part on it that the tensioner hits up against is too soft. The fix by JLR was to add a bit of hardened metal at this spot.
I registered my car and requested clarification of engine oil type. Their customer service team referred my query to their engineering team for followup.
Not sure they have any idea what they are talking about!
First of all their web page recommends 5W-30 for the 5.0 when we all know it takes either 0W-20 or 5W-20 and most definitely not any 30 weight, and now they are talking about a 2014 4.2 when the 4.2 was retired in 2008/9.
Jaguar makes no recommendation of using 0W-20 in the XK series for the US or Canada that I have been made aware of.
After I bought my 2012 in 2014 I only used a dealer for my yearly oil service. They told me they used the recommended Castrol 5W-20 special oil .. Then in 2016 at my annual oil change they told me they had a TSB requiring they use the new special recommended Castrol 0W-20 stuff. That what was used until I sold it in December.
Pennzoil recommending 5W-30 on their website is the reason I started this thread. Things change and no one cares to update there websites. I think either 0W-20 or 5W-20 should be good. Giving a reply about a spec, 2014 with 4.2, that never existed leaves me scratching my head. I requested Shell clarify and update their website concerning their recommendation given Jaguar is now recommending 0W-20.
they told me they had a TSB requiring they use the new special recommended Castrol 0W-20 stuff.
Any chance someone here has that TSB? I'd like to add it to my findings..
The last I got was JLRP00119 from Feb 2018 excludes North America from changing to 0W-20
As of that date, JLR says 0W-20 is an acceptable substitute, but not the recommended weight.
I wouldn't doubt they could have followed up with North America making the switch, but no one here has provided documentation for it yet.

I don't have a copy of what I was told but I'm sure if you contact a dealer they may be able to get it to you. My dealer was in Albany NY.

My cars are out of warranty, and never sees a steal-er-ship. I have no need to even talk to them.
Doesn't someone have access to topix? Can they look up any changes to STJLR.03.5004? Has JLRP00119 been superseded since Feb 2018?

You guys had this discussion a few months ago. Ralph's dealership used 0w20. CleverName presented the TSB's provided by Jaguar then. (Cambo posted them originally in May last year in yet another oil thread). Last one I see is JLRP00119.

Stuart had posted the TSB about the oil changing from 5w20 -0w20 from jaguar a few month back
The point CleverName has been trying to make for some time is:
JLR has never told anyone, stop using the 5w-20 and use 0w-20.
So anything else is an interpretation. Fine; but then further interpret why they never asked anyone to stop using 5w and started using 0w20 in FTypes.
0w oil becomes 5w, or even 15w after extended periods- thats what soot loading does. And all this is to do with 12 month oil change. If you change every 6 months, different physics apply to you.

I agree that was his point. He's made it before and I agree with him, hence my post. If someone can't show otherwise, why are people diverting from the latest TSB?
Why did we divert from the 10 commandments- the neighbor's wife had a better value proposition.
Seriously, how do you mean diverting?
Indeed she did.
First, a correction. By we I mean you guys with your 5.0 engines. The latest TSB calls for 5w20 oil in the US. and Canada. To the OP's original question, why divert from that TSB (aka seemingly Jaguar's last known recommendation)?

QC I assume you are thinking that a 12 month change would be somewhere around 10-15 K miles . I did 12 month annual changes but I only put on an avg. of 4 K miles.
I've not seen anything newer............. So the NA market remains at STJLR.03.5004

Your assessment is accurate, but the cause is not.
All oils are created at a base weight (10W, 20W, 30W etc.) but it is the additives that modify the oil weight to change based on temperature.
Unfortunately, these additives have a low vapor point so they inherently evaporate as the oil goes through repeated heat and cooling cycles. With these additives becoming depleted, the oil slowly over time returns to its base weight.
