Mine consumes 500ml on 4000miles with everyday use and 45miles trip (home to work and back) at least. I don't fill it up since I replace the oil every 4000miles and I think that this oil consumption comes just from the turbo since it's air intake is allways oilly...

 

mines on 45k gets abused week in week out by time next service due always 3/4 up between min and max on the dip stick. I dont bother with coil changes every 3k its wsste of money and deterimental to service life imho oils moved on long way since the 90's
