The first one was pretty high for only 13k, however could some of that silicon been gasket material from any repair work? Seems odd that the 13k run would have 40ppm while the 23k run had only 17ppm. That second run isn't bad at all, looks like the filter is doing ok.quote:

Hey Guys,
I'm using a Amsoil(UNI)Filter on my 00' Silverado. My oil analysis came back the first time at 13,000 miles with a silicon# of 40, the second time at 23,000 miles with a silicon# of 17.
I'm using Amsoil 0w-30 Series 2000 motor oil on both these samples with 12 months on both as well.
My question is are these high numbers of silicon?
