Actually, my company supplies the oil quality sensor. So it exists. Furthermore, it is stated in the technical handbook.
For sure, the oil quality sensor is not the sole determinant of the approximative oil life left, but it is one factor in the computer's determination.
If you consider that most of my mileage is on free-flowing roads at highway or autobahn speed, the wear and tear I put on the engine is relatively low compared to suburban stop-and-go.
But I'm not imposing my opinion on anyone.
