Some engines will use more than others - thats just down to manufacturers tolerances, how its driven, etc. My LCR hardly uses any at all, topped it up slightly just once between the 10k & 20k services. I wouldn't have a
problem with it using a little oil - as long as there were no leaks anywhere!
Some cars use loads - Alfa's have a reputation for it, as much as a litre every 1000 miles! Sod that!
