ihatetochangeoil,
Thank you for posting the UOA. Pertaining the the Silicon level, would you please update us with the brand of air filter you are using? Also, with the oil you are using, is it known for having a high dose of Calcium, because I usually see cCalcium levels around 1,600 to 2,300 in the VOA / UOA posted on this site. In addition, have you opened up the Centrifuge to see the amount of particles that it has removed from your oil? I'm just asking these questions since your engine is the only one I have ever heard of being upgraded with the two diferent external oil filtration units. I look forward to the next used oil analysis.
