Can anyone more technically astute on the eta engine go into further detail > on the low friction, but consequently quicker wearing aspects of this motor?
The main area where the eta motor is ‘low friction’ is the valvetrain. The eta cam only has 4 bearings, as opposed to the 7 on other small-6 motors, and the valve springs are considerably softer too. Other than that, the lower revs inherently brings about less frictional losses, and the tall gearing/high load reduces pumping losses by forcing the driver to use a larger throttle opening for a given speed.
