My latest was a couple weeks ago and it showed zero silicon. Silicon is dirt. Also my oil showed very low for iron. Iron indicates machine part wear.

Whoa, what oil brand are you using? Many oil companies add a tiny bit of Si as an anti foamant (off the top of my head, Blackstone labs recommends Si levels less than 5 or 6 (whatever units it is they use). I'm not calling BS - just curious (I usually range between 1 and 3 on the Si level - I get oil analysis done at every oil change every 10K miles).
