Bizarre. Over here the service intervals are every 2 years for the XE with the same engine. I took delivery of ours in July 2019, we have had it in for its first service which was scheduled for 2 years/34000kms (so that would accord with the 21000 miles for the UK version) in July '21, it wont be due for its second service until July '23.
It uses castrol 0W20 oil, according to the service report.
Personally, I'd rather take it in once a year, just to make sure something little isnt becoming something big, although my missus is like a bloodhound for sniffing out mechanical issues. Despite her continuing to say that the particular car "feels like it needs a tune up", she has pretty much never been wrong when she thinks something is amiss.

Won't effect the warranty as long as you use oil which meets the Jag spec.
I use Penrite or Valvoline fully synthetic 0W-20 which meet ILSAC GF-6A and I get them from Supercheap Auto when they have a sale on for around $40 per 5 litre bottle, around one third the cost of the Castrol Unobtainium if you could find it.
If the I4 has an oil extraction tube like the V6 and V8 then it's a piece of cake to do, and even if it doesn't and you have to get down and dirty underneath with underbody panel(s) and a sump plug it can't be all that difficult, either way it would cost a lot less than what a shop would charge let alone a JLR dealership.

BruceTheQuail, we agree on the synthetic oil weight: 0-20. I only drive the Jag about 5,000 miles a year, so changing the oil and filter at 1-year intervals is good for me. Especially when JLR pays for it for the first five years.
OzXFR, I would point out that my owner’s manual calls out specification STJLR.51.5122 for the the Ingenium 4-cylinder engine oil.
There is no maintenance listed for the turbocharger. I’ve heard of no weaknesses or failures with them, but I’d like to know more about that before something untoward happens!

To be clear, the AJ126 and AJ133 are forced induction engines via supercharging and are not naturally aspirated.
The main areas of concern for the V8 and the V6 variant are the plastic cooling system components, which can cause catastrophic engine damage if they fail. Early AJ133 engines had issues with water pump failure and should also be inspected for any signs of coolant loss or seepage. There are now aluminium pipes to replace the water outlet under the supercharger to eliminate that potential failure point. The plastic heater pipe between the cylinder heads at the back of the engine is another know failure point.
On both the V8 and V6 any drop in coolant level requires immediate investigation as to the cause.
Other than the coolant pipes, the AJ126 and AJ133 as fitted to the X152 appear to be robust and capable of well exceeding 250,000 km with proper maintenance.

Any comparison between engines should also include the following potential failure points absent in the 300 HP Ingenium car that can be easily addressed in the 6 & 8 cylinder versions either preemptively or by increasing the maintenance regime.
Here's a few that may not have been mentioned above to keep an eye on:
Also, the Ingenium engine has a dipstick.
further info on the Ingenium:
How Jaguar optimized the Ingenium gas engine for the F-Type - Autoblog
Suggest a test drive to see if this version meets your needs.
Put it in SPORT/DYNAMIC mode and be prepared for a big surprise.
Mine is no garage queen, but a daily driver. The aftermarket exhaust system was a great addition !!
Roll the windows down and enjoy the sound of the spinning twin scroll turbo as you throw her around the twisties.
BEST !

- water pump/bearing failures.
- transfer case/front differential issues
- electronically controlled rear differentials - increasing the service frequency has been suggested.
- hood vents allowing water to drip onto fuel injectors causing major issues down the road.
- supercharger couplers
- active dynamic faults

Perhaps he means Dynamic Mode Faults, which are discussed a bit on p 5.18 of this 2013 doc.
