And ultra thin rings


And that roll is:

Low tension rings take less soot to stick in the piston groove. Change the oil before it's saturated with soot and coating engine internals.

Cam phasers can stick.

Also, people are not used to checking oil levels anymore. Rings stick, oil usages begins. Turn fast or break hard enough to uncover the oil pickup. Oil pump sucks some air. Now the hydraulically tensioned timing chain can jump and ruin the day in a hurry.
