Previous filters run during this oil change interval can be found here:
The pictures below are from the fourth filter from the second run of HPL HDEO 5w-20. The oil now has accumulated 23,500 miles of use. HPL HDEO 5w-20 has been in use for a total of 51,900 miles, again this is the second run. The UOA has been sent in and the results will be posted when I get them back.
This is the second filter with no carbon chunks, so I believe it's safe to say the cleaning is done. No carbon could be scraped off like two filters ago. There was a smaller than usual amount of metallic flakes in this filter. In the bright sunlight the flakes are visible, but to a lesser extent than we have seen in the past.
This Fram Ultra did not have a screen backing the media.
Much to my surprise I found that the crimp that joins the media ends to form the element was perforated the entire length of the crimp. Non-filtered oil certainly by-passed the media during the run of this filter. It appears that the crimp machine wasn't adjusted properly and punched holes in the media. This is the first time I have ever seen a Fram Ultra with a perforated crimp. It will be interesting to see if the UOA shows unusual wear metals. The new filter did not appear to have perforations at the crimp.
