Every engine has a "power band"...that is where the cam's peak hp/tq is built/delivered.....in short, just like in a racing condition where you want your gears to be set to allow when you upshift, the next gear should be at the bottom of the "power band".....use a light throttle, you get better mpg. If you are getting clutch chatter, engine lugging, etc., then you need an "Ol Timer" to show you how to drive a stick......because all of this is controlled by you understanding engine loading, etc......if gear selection, etc. is done correctly, the drivetrain should not even feel your actions as a driver..... no wear, no damage. If the drivetrain does feel it, jerking, chattering, vibration, then your slection/actions are not appropriate for the road conditions.
