All prior oil changes had been with Castrol GTX. Oil was drained & oil filter changed when each sample was taken. The 2nd sample is showing signs of the intake manifold gasket leaking. I brushed that aside after the 3rd sample came back pretty good.
I don't belive this is a very good wear report, but it's more good data for the website. Iron is high but came down to more reasonable levels on the 3rd sample. I was doing these tests to see if there were any differences in oil filters. This was long before I knew of BITOG.
Any input?
