I recently started a post asking if an Italian Tune Up is really benefitial for a engine, I got answers from various people saying how hard you have to drive the car for it to be benefitial and to be called a ITU, but this reports were a little confusing for me because they went against my conception of engine wear relation to WOT driving for extended periods of time.

I was averaging about 115MPH in Upstate NY in regions so remote no radio stations came in. For a long time. THEN did normal speed moves with fast (90-ish, about normal for Upstate NY) and hard driving for two hours or so.
Never redlined except for short periods of time on hard acceleration.
You could really get on it for about a half hour AFTER FULLY WARMED UP and achieve an ITU. Maybe a little bit longer. A fast, LONG highway drive could achieve the same.
Doesn´t this kind of engine load for extended periods of time causes premature engine wear?
Can normal passengers vehicles take this abuse and still last 300k miles at least?
How long engine last for the car enthusiast that do thousands of miles on canyon drives and track days?
