981 Engine Oil Consumption (in-between scheduled service)

[turbo4ever]

Having read this http://www.caranddriver.com/reviews/2014-porsche-c... article, is actual engine oil consumption so high that it needs additional fillings in-between regular service events?

Please post even if your car does not require additional engine oil. State engine (2.7, 3.4, 3.4 GTS, or 3.8 GT4). Many thanks!
