Hi I have a 10 year old f22 218i that is burning oil. It asks for a litre every 500 miles. Yesterday, whilst topping it up I noticed smoke coming out from the filler. What do you think could be wrong? Is this a common problem?
That amount is probably due to worn piston rings but there could be other problems combined.
Sometimes you can mask it a bit by going up a ‘thickness’ of oil. If you aren’t already on 5w30 you could try it but I think the amount it’s burning probably needs more detailed inspection.
