I am kind of anal but whenever I do anything where dirt can get into the oil...ie heads off, rocker covers off, oil pan off etc. I make sure all crap is out of the oil. I run an organic oil for a few minutes and drain it/replace filter. I replace it with the same oil and filter and drive it for a week. then I drain that and replace it will my regular filter/synthetic combo. To me, oil is cheap. Might be overkill but I sleep well at night
