I'd guess they're about the equivalent of a 140HP, performance wise so yes, around that.
Joe Average does about 50 hours a season, so the penalty is approx. 300 litres or €400 in my money.

EDIT: The 2 litres of XD100 is an exact measurement. I filled the reserviors before departure and refilled them on return. The oil bottle was just
at the 2 litre mark and filled the reservoirs perfectly. Sweet.
