If you are pushing in the gas and the engine is shuddering your RPM is too low. The oil film that hangs out in your bearings can get compressed out of the bearings and you will have increased wear. I lope along at 1000 rpm frequently l, 5th gear and mph, the engine is smooth so no worries. If I try to increase my speed and the engine vibrates it means I am applying too much pressure to the accelerator or I need to down shift.

An engine is a very robust thing, you really have to be abusive to do much damage. If you are being abusive to it, it will complain if you are listening for it.
