What brand and spec oil is used in the Jaguar? Is this a Turbo engine?
Maybe you require something with a more aggressive detergent package or you have a ringer for a motor.
That oil is not golden, and it is hard to visualise the colour on the stick. If it is somewhat chocolate brown appearing on the dipstick, it could well be very contaminated.
On the exhaust soot, I would say since most vehicle have two converters, that the soot occurs during startup and just the first few minutes of driving. After the converter gets hot I would assume it would catalyse carbon to CO2

It has 0w20 Shell Helix Ultra in it.
The engine is a 2l turbo direct injection engine.
You are probably right about the soot. I highly doubt it'd produce much during normal operation, just on the initial high fuel ratio start and warm up.
