Maybe it depends on what oil you use - perhaps you should ask for advice on which oil to use?![]()
A lot of people think they use oil because they get all out of sorts if it drops a few mm in thw window. If you overfill it just throws it out the back.
140,000 on the clock and it's never used a drop![]()
2013 around 1/3 ltr per 6000 miles as I have to top up just before serving 
Mine 2012 TC does use oil.
Started off at about 1/3 litre / 1000 miles but it's improving all the time (I bought it with 3k on it and the previous owner was an older gentleman who I think, babied it)
