Yep, that's true (well, except for the 'very advanced' part); STP is useless gunk, too, unless you're trying to nurse along a thoroughly whipped (worn out) engine.
In the advertising-marketeering world of words on bottles and counter displays, sure. But in the real world, it actually causes the oil to aerate (foam), greatly reducing its film strength.
Simple: because they are built much more robustly than gasoline engines.
There is no sound basis for that claim.
And me, I haven't had a water pump failure ever since I started swinging my left arm in a figure-8 pattern twelve times a day, eleven years ago. I guess it must be working!
