It’s been available for a while as I bought a couple of 1l bottles a few months ago.Besides full synthetic 0W-20 meeting STJLR.03.5006 you want one that meets ILSAC GF-6A, some do some don't.
From my research the latest version of the special Castrol Unobtainium brew is still just that, only available at/from JLR dealerships, and it doesn't meet ILSAC GF-6A either. I for one prefer any full synth 0W-20 meeting ILSAC GF-6A and any one of the older JLR specs for the 5.0 V8 such as Ford WSS M2C 945-A.

Thank you for contacting Castrol North America.
Castrol EDGE Professional OE 5W-20 has been discontinued as of January 1, 2021.
Most Jaguar and Land Rover retailers have already switched to Castrol EDGE Professional E 0W-20 and soon Castrol EDGE Professional EC 0W-20 which are both backward compatible to any engine (AJ 126, AJ 133) that required Castrol EDGE Professional OE 5W-20.
Castrol EDGE Professional EC 0W-20 is replacing Castrol EDGE Professional E 0W-20 as it combines the cold climate performance of Castrol EDGE Professional E 0W-20 (STJLR.51.5122 oil spec) and the fuel economy of Castrol EDGE Professional E C5 0W-20 (STJLR.03.5006 oil spec) into one product.
Like Castrol EDGE Professional E 0W-20, Castrol EDGE Professional EC 0W-20 will only available for purchase through Jaguar and Land Rover dealership locations.
Presently Castrol EDGE 0W-20 E is available for purchased in the retail space in a 1 quart bottle size covering the Jaguar and Land Rover STJLR.51.5122 oil specification:
A new product, Castrol EDGE 0W-20 EC, covering Land Rover STJLR.51.5122 and STJLR.03.5006 oil specifications is expected to replace Castrol EDGE 0W-20 E in the retail space late 2021.
- Castrol EDGE 0W-20 E – Part # 15B4B1 – 6 x 1 US Quart Bottle
Thank you again for contacting Castrol, we value your patronage!

So Castrol are saying the latest spec should be available from retailers later this year, but it seems unlikely it will meet ILSAC GF-6A.
Miles easier just to not bother with a warranty. Might as well throw your money down the drain.I would buy your oil and filter from your local JLR dealer. If you put a non genuine filter on it or fill it with anything other then the genuine oil you are opening up a can of worms with your warranty. Should you have any engine problems with it, you don't want to give them an ounce of space to wriggle out of the warranty commitment they have.
Personally, I'd fit genuine filters, genuine oil and keep a copy of the receipt showing it purchased from the dealer so there's no doubt in anyones mind about what you're putting in it.
You might even be better getting a VAT registered garage to do it, issue you a receipt and make sure it states on the receipt that genuine filters and oil were used.
Just my 2p worth though
My extended warranty has paid for itself at least 3 times over so far so happy to pay it.Miles easier just to not bother with a warranty. Might as well throw your money down the drain.
If we're talking about manufacturers warranty, then just keep receipts of what you have bought.

I’ve had 4 main dealer services at 3 dealerships - according to the paperwork they have used castrol x2 (same dealer), Petronas and shell helix. I assume they all met spec.Just don't tell them you self changed the oil, and as long as you use a genuine Jaguar/Land Rover oil filter they'll be none the wiser, even if you do need to make an engine based warranty claim. They're hardly likely to send an oil sample for analysis suspecting it's a different brand to Jaguar supplied. And what brand do the dealers use anyway? I very much doubt they use lots of 5 litre plastic bottles of oil, they'll have a bulk tank. May well be the same oil in the bulk tank, I've no idea, but a bulk delivery of a cheaper brand would save the dealer a few quid...
There will always be the exception, but in general for most people they are a waste of money. My view is that they're a business, there to make money. They don't make money by doing everyone favours, it will never favour the customer.My extended warranty has paid for itself at least 3 times over so far so happy to pay it.

Like every insurance policy out there. They’re all a waste of money - until you need to claim against it.There will always be the exception, but in general for most people they are a waste of money.

Still amazes me that wasn’t covered.Until my recent A/C problem where the warranty specifically excluded the item that had failed (cooling fan), I too have had good use of the Jaguar extended warranty.
That said, I shan't be renewing it next March . . . . . probably.
