370Z oil consumption

ZeeYouLater

There are only two possibilities for hight oil consumption

may quality issues including normal human overload because of cost reduction on the powertrain production (price orientated hight power product not hand crafted) or coustomer rpm abuse at cold oil
a) piston and ring surface (honing in production)
b) intake valve

are the heads replaceable in the engine bay or does the engine has to be removed because of the abnormal "low" noise that was mentioned , this sounds more like a head problem. Abnormal piston noise is louder :-)

I have no oil consumtion @ 10k km with the first oil, what is normal for proper brake in and of course no abuse and all todays engines behave like this if there was no quality issue in production.. oil type of course didnt matter because of API (for the oil popes who belive in healing through blessed fluids..best indulgence discussions)
