52,807 miles on vehicle, 6100 miles on this oil (Oct/04 - Dec/05). This oil is combination of M0304 and M02. Maybe that explains why the used oil sample has higher additives than the virgin sample wich is M0304. I am now out of M02 and could not get any analyzed. The oil filter is a Ford Long Life and a Fram air filter. One litre of oil was added during this run. Metro Tech flagged the high silicon level and advised an oil change. I'm disappointed with the silicon level. The first number represents the used oil sample, the second number the virgin sample.
