2013 SLK250 Turbo, Mobil 1 10W/40

I'm a little concerned about silicon. I replace air filter at last oil change.
Maybe someone can figure out how to post this for me.

Silicon isn't an issue, besides some silicon may present in virgin oil sample.
Reasonably good metal wear rates, and used oil is still serviceable though viscosity drops quite a bit.

The slightly elevated silicon could just be the result of you replacing the air filter. Some dirt could have gotten pushed in while you were swapping it. Plus, a new filter doesn't actually filter as well as one that's already been loaded with dirt.

Thanks for the help posting and your input.
I used Fram extra guard air filter. I vacuumed out air box completely first. Used Mercedes OEM oil filter.

It is interesting comparing this to my older 1999 SLK230 supercharged 2.3L that this car has replaced.
Old SLK230 Iron 6, copper 10, and silicon 7, Newer SLK250 Iron 16, copper 4, and silicon 11. Both using M1 0W/40
And then my 1999 Sentra 1.6 Liter Iron 24, copper 10, and silicon 16 and the Sentra never burned a drop of oil.

What components use copper?

I may go to OEM filter to see if I can get silicon down.

What are the thoughts on Fram Extra guard air filters? They claim 2X the filtering.

2X the filtering of what? Marketing works wonders. The hot tip is the official what ever of NASCAR. NANO works for me.
