Yeah mines a 56 plate and i burn about 1L per 1000 miles, known issue so its worth keeping an eye on. Not quite as bad as Adrian's was though....
Try changing your oil. I changed from using motul and castrol edge to Fuchs Titan race pro and it's cured my oil burning issue. I used to burn a litre every 2k but that was high revving and giving it the beans. I barely use any now.
So you really need to change the sticker on your car
