Ahhh, but then we'd have to calibrate it to AMSOIL anyway. Interesting though; thanks for the feedback.
BTW, the original post link seemed to indicate that the new technology was going to actually monitor the oil quality itself, claimed through some viscosity and conductance measurements. The last paragraph reads:
"One single sensor, and the intelligently processed information which is already available on board the vehicle, are sufficient to determine the various parameters of the engine oil. This onboard oil quality surveillance is currently being prepared for series application in commercial vehicles. The resulting precise calculation of due times for maintenance stops will allow oil change intervals to be extended by about one-fourth."
If applied in an AMSOIL system, might it not extend the change even longer? Everyone seems to claim that when oil analysis is done at 15k miles on AMSOIL systems that the oil still tests fine.
