If we assume that engine wear is based on mileage, hours, or use:

It's really revolutions of the crankshaft.

If you drive around at 3000rpm instead of 2000rpm, at the same vehicle speed, you are doing 50% more engine wear per mile.

it doesn't necessarily work out that way, but it is a good model to keep in mind.
Buzzing the redline all the time is tough on a motor.
