Inspection – bring oil yourself?

Hello Jag fans, since I was used to bringing my longlife oil with me at Audi (1L approx. 6 Euro, with Audi directly 1L approx. 24 Euro) I wanted to ask how this is with Jaguar. Can you bring your own oil with me? Or are they looking at you stupid? I find it an absolute impudence like other manufacturers to get to the oil costs. I think Jaguar will be no different here, too, right?! Since I usually do everything myself on the car, but I still have 1.5 years warranty, I probably have no choice but to go to Jaguar 🙁 Maybe someone knows the cost of an oil change for a 2.2 D (6 liter oil, 5W-30) at Jaguar?
