VW GTi burning oil

There are all sorts of possible explanations for it, from piston to ring clearance, ring tension, ring design, etc. What we know from reports we get from VW owners is that VW engines do consume oil and it's a wise practice to check the oil level regularly. An interval of 15,000 km is too long, but carmakers today are stretching the boundaries to cut running costs. If it were my car I would be changing the oil every 5000 km.
