This is due to manufacturers knowing that US customers do not following the factory maintenance schedule.

I just scoped my cylinders in the 2006 Prius with 215k miles and the block is junk. Regardless of the oil change intervals the previous owners did it didn't keep it from tearing chunks out of the cylinder walls. And you can't bore these engines so my engine is now junk. Three cylinders have chunks missing out of the cylinder walls and all four have grooves.
