some european vehicles do have an oil quality sensor but non of the US vehicles do.

Why wouldnt you consider it an oil quality sensor? The sensor from what I read is based of you would think the recomended oil for the car and when it should break down based on all the data it has collected. In my eyes if you use the correct oil for the car IT IS an oil quality sensor. It just does it another way.
