To rev or not to rev. That is the question.

[Sharky]

Mhhh, hadn't noticed this part of the forum. Anyway, here's my question. I've heard a lot of different opinions regarding how much should one rev up the car in normal driving. Some say that you will screw up the engine if you don't rev it up as there is poor lubrication, an uncoplete combustion and the engine is "forced". Others say that if you rev it up you'll damage the engine because there's too much friction, heat, forces, etc etc etc. I heard somewhere that one should always run the engine over the max torque mark. So, for instance, if the max torque of the car should come at 2500Rpm then one should rev it up so that when you shift down the revs fall to 2500 rpms. But, that would mean that if the max torque of the car comes at 5000 rpms then one should always keep it above that rpm level despite being very high.

So, how much should one rev up the car in normal driving.

My particular case. I have a Pug 205 and it's max torque comes at 3200Rpm and the rev limiter starts at 6200 rpms. I always run it between 3000 and 4000 rpms. Am I doing it right or wrong?
