Warning message pops up when the oil level gets to low. "add 1 litre!"
Excessive oil consumption is not normal.
My excessive oil consumption was due to oil leaking through the turbo seals -common on the N54 engine.
Yours will be N55 so may not be such an issue...
Car: 2010 Jaguar XFR (Cat-back exhaust)
