We have been using euro standard low sulfur fuels since 2020, but then again I havent done any UOA after 2020, maybe I should start again.

The V-12 Jaguar engines sold on the US market were primarily the answer to the rigid smog control regulations that were making their legendary DOHC straight six impotent. The V-12 didn't make much more HP than the previous 6.
The Euro versions were another story.Properly sorted out though, the big 4 door sedans were smooth performers and made nice touring sedans.
To the OP, I am curious what the owners manual called for regarding viscosity ? 0W-40 doesn't seem likely, however your results speak for themselves.

Jaguar manuals of that era usually detailed a large range of acceptable viscosities, pretty much anything from 0w30 to 20W50 so long as the weather permitted.
not quite the story. despite of owning the rights to build a lighweight and powerful V8 they chose to dump a lot of money developing a ridiculously heavy and inefficient V12.
when smog standards started tightening they redesigned it into the “HE” V12 which produced pitiful numbers in all configurations. a few years after that they quietly admitted defeat by building the AJ6 family.
all the factory sanctioned race cars used the older “flat” head V12. much later on the 6.0 V12 addressed the glaring issues but by then it was already time to move on.
anyways 10w30 energy conserving was what they prefer you use for best economy

Yeah, post as little info as you can/want. No MFG, no model, no driving style/attributes.
This car is definitely not a short tripper.

Did you not read his posts in the thread? It was rather interesting to guess which motor was pictured, just had to read a bit. Kinda wished all valve cover shots were handled this way..

They’re selling like hot cakes with long delivery delays. This post just doesn’t make sense…
Selling like hot cakes, not so much, long delivery and low inventory probably, like every other car manufacturer, Jaguar only sold about 100,000 cars last year world wide, less than 20,000 in the USA, BMW, Mercedes-Benz, Audi, Cadillac, and Lexus way outsold them.

No they’re selling better than they ever have here in God’s country. Just too hard to get though due to semiconductor shortage and COVID.
Tata group Jags are definitely not forgotten in my area and are very popular as well with the old money and hip hop money crowd - Jags and Land Rovers are about as common as a Mercedes E & S and BMW 5 & 7. Toss a rock in traffic and you will hit one or more of the above.
