Harry: Silicon is slowly increasing, so we're wondering if maybe it's time to check or change the air filter. Then again, you had mildly elevated silicon in June and it went down thereafter. If you did'nt do anything to the air filter back then, maybe the xtra silicon was an additive in the oil, and maybe it's the case again now. Moly has increased, presuably due to the moly additive you're using. Do you notice any difference with it? (Yes) Potassium is still, mysteriously high. The TBN is strong though, and the Particle Count is clean at 16/15/12. No new problems found.
