WRONG, an automotive engine doesn't turn 5200 rpms for hours on end. At 50mph
in a car a 4 cyl engine is turning an average of 2600-2800 rpm. So if you want
to further use this analogy calculate 900 hours at 100 mph or 90,000 miles.

To compare it to your car example:
at 50 miles an hour, it would take 2000 hours to travel 100,000 miles. Most
people would think that they should gt 100,000 miles out of a car before
major engine repairs.
