I began a test this evening with WMO for the benefit of others that do not have a CF.
This is a sock filter, 5 micron, that I "prefiltered" the WMO before the test run thru the CF. The photo is taken with the filter turned inside out after use. Te bottom of the filter had enough sediment that it could be removed with a teaspoon.
This photo shows the the accumulation on te CF wall. This test was conducted with only about 13 quarts of WMO fom my personal truck. The oil was used for 5000 miles. Note in the bottom of th image how the sediment appears rippled, as it was very thick and sticky.
I smeared the debris on the CF wall with my finger and it was somewhat dry and tacky, like half dried paint.
Notice when the CF wall was wiped with a dry paper towel, the rotor has what almost seems like sand still clinging to the CF wall.
To conclude, this very short CF run of about 13 quarts of WMO was centriguged at about 65*F. I surprised how the particulates were tacky, and would stick to the wall. The more abrasive matter on the CF wall could be felt between your fingers when wearing latex gloves. The thick, tacky stuff clinging to the wall still seemed slick to the touch, but the particles could easily be felt between the fingers.
