I'm not sure what he means by that. He's implying that people with oil consumption issues downshift into high RPMs frequently? Or does doing a few high RPM downshifts then induce a persistent oil consumption thereafter?

He said Nissans' observation is that people with MT down shift more than those who drive AT's. Higher revolutions and making the engine work harder wears out faster. (Yeah no kidding). So I asked him about the SRM and should I not use it during break in. Answer: The SRM helps with engine break in and smooth shifting.

I am not 100% sure he was actually a real engineer.
