All engines are produced with a certain amount of slack built in around all moving components (piston rings, valve seats, guides etc) to account for thermal expansion of the metal

The higher the RPMS the engine sees the more metal wil wear and the more likely you are to consume oil.

I really struggle to understand all those who swear by red lining ALL the time in every gear. Just because the engine is designed to rev high doesnt mean living in the high rev zones wont have consquences.
