Both lead to wear on the engine. As I said, if you are not lugging the engine, you are not loading it unduly with low RPMs. If you are flooring the accelerator all the time, you ARE loading the engine unduly. Would you want to take you car to the drag races every day? Would it comfort you to know that you are not lugging the engine?

If you are running at 6000 RPMS all the time, you are elevating friction, heat. and wear. Pistons have to reciprocate. When you move them at 6000 rpms rather than 3000 RPMs, and they have to reverse direction, at which RPM do you think there is more stress on the cranshaft and the pistons?

Think about it.
