I was told by a friend that is a ford tech that the oil meter simply monitors the time your ignition is on,that it doesn't really monitor your oil. With that in mind the last time I changed my oil I went to reset the meter but it only reset 80% so I tried to reset it again and it dropped to 70%. Currenty the meter is reading 38% after 1200 miles. I am running full synthetic 5-20 and a Pure One filter. There is no way the oil in that motor is that depleted already. Has anyone else found inconsistencies like this.
