Actually, although slightly off topic (apologies), talking about topping up oil, my Scirocco is my first with the CR (common rail) engine, and I have to say in 2½ years of ownership, I have never once - ever needed to top up my oil. It never moves between services. My older Golf 5 with the PD engine would regularly go through 1-1½ litres in between the annual services.
TBH, I know more mates with TSI and TFSI engines (especially Polo GTI) that drink oil much more than any diesel
