Well it’s either burning it or leaking, it  can’t be anything else. I would put a big clean piece of cardboard under it after a long run and have a look the next day to see if there’s any oil on it. If not it’s burning it.

Are the breathers spotless?

These modern sealed engines drink oil as a side effect of the breather process... They're designed to, so the emissions tend not to be affected as long as the breathers function correctly  ;)

Mileage will also have a bearing along with previous history...

Which petrol engine? The THP150 (aka N14 in the MINI) generally drinks oil like George Best did alcohol. Known for weak blow-by control (piston rings) and poor head oil control (stem seals and valve guides both wear), coking of the inlet tract & valve backs due to the combination of excessive blow-by and direct injection providing no 'cleaning' effect on the intake..

THP150 is the 1.6 turbocharged engine (and variants).

seals were done as they needed doing. original owners couldn,t afford the towage & to pay for timing belt & all the work it entailed to put it back on the road. they eventually told the workshop to keep it & sent the guy the documents in lieu of payment.
