Carlos from Spain:
I know it's not the same engine exactly but my GTS has 25,000km now and I have not had to put any oil on it whatsoever since I drive it off the lot with 0km.

Yes, I have a similar (but non-X51) motor in my GT4 and it literally does not use 1 drop of oil (doesn't matter if I drive slowly, fast, or go to the race track).  Pretty remarkable motor in this respect (never had a Porsche that drank zero oil before).

The motor in the GT3 and RS are known to drink some oil (more when tracking), but this sounds excessive (or an indicator error) in this thread...
