Facts not in evidence? Here we go. More gas high RPM fans to do the same as low RPM diesels.
What's high rpm and what's low rpm? I can pedal my bicycle about 70rpm for several miles before I give out. At what rpm do you suggest an engine won't survive? 2000rpm is a blur. You can't see it, much less pedal it. 4000rpm is also a blur. What makes 2000rpm "low" rpm in your mind? Compared to a 19000rpm Formula One race car, 4000rpm is real close to car and pickup truck size diesel rpm. During R&D, Chrysler ran the 5.7L Hemi 300 hours at full throttle, full load peak hp rpm. Upon tear down, only normal wear was observed. Nothing melted or broke. I gave my 5.7L Hemi no mercy. At 120k miles when I traded it, it still ran like new, burned no oil and had good power. It saw 4500rpm any time it needed it. A roofing company bought it and I still see it occasionally out working hard. Because one is afraid of 4k rpm doesn't mean it's killing the engine.
300 hrs is like 15,000 miles. There should not have been any wear. Heck, it shouldn't have been broken in yet.
The F550 I drive at work runs 2750-3000 RPM day in day out loaded very heavy. I believe it is right at 65,000 miles right now and runs like new. Run your gasser at 30,000#+ at 4500-5000 loaded that heavy for 65000 every time you take it out and tell me how it fares. This is the wonderful 6.0 also.
