I also read somewhere that while GM uses a computer to calculate when the oil change will occure (Cheap GM version of FSS), MB uses a sensor to check for conductivity between the 2 points on the sensor to decide how "used" the oil is. On my GM, it tells me to change the oil and when I reset it without changing the oil, it is fine to go on till the ECM tells me to change it again. I would like to try that same experiment with the MB and see if it tells me "You #$#)*% liar!! Change that #%#) oil NOW."
