So what are they sensing? I doubt if their measuring acidity or moisture content. Maybe they're looking at turbidity with an LED and photosensor. Further down in that white paper they state the different regimes, and it seems like the only reason they would need to do this is if the sensing system can't tell when the oil needs to be changed based on the oil condition.

The automakers demanded the phosphorus limit be put in place by API because phosphorus will shorten the life of the catalytic converter. The amount of phosphorus going through the converter depends a lot on how much oil the engine burns. See "http://www.aa1car.com/library/converter.htm" Since there are plenty of synthetics and non-synthetics that meet the API levels, there is no reason to risk using a non-API certified oil.

If you car is burning oil you should get that fixed. The main reason for using a non-API certifided oil is because the API test is lacking. After all its brought to you by the same people that say change your oil at 3,000 miles.
