I'm saying that the algorithm is telling you to change your oil (ie the mileage till service won't go up) when you put new oil in, despite the condition sensor saying the oil is ok.

And how are you an expert on what the oil condition sensor measures?

Aren't you speculating?
Reread my post. My point is, it's all based on the algorithm unless the sensor detects a LOT of conductive contamination in the oil. This would include metals and maybe water with dissolved ions, but it wouldn't include anything about silica (dust) or anything about the lubricity or viscosity of the oil. Many people, I think, are under the impression that the sensor is like an oil analysis lab in their engine.
