Take the mileage of the oil , in your case, 20,000 miles, then divide it by 1000.

20,000 / 1000 = 20

This number (20)...

If your iron is higher than your (mileage/1000), then you likely have excessive wear somewhere. if it is less, then your oil is doing a decent job.

Your iron shows 16. This is less than 20 ... that is a good sign.

Which one is soot?

I guess resample next service and then compare again?
