The first filter from this second run of HPL HDEO 5w-20 is here:
I have stated that I will change the filter every 5,000 miles until the filter no longer accumulates carbon that is being cleaned from the engine internals. When I pulled this filter, it looked pretty clean and I almost put the filter back in (cartridge) and continued to run, but decided to cut it and inspect so we could get a close-up of what the filter has collected. I always take the cut filter out in the sun so we can get a close-up in good light.
At first look, the filter looks pretty clean and we don't see the large chunks as we did in the past.
However, when I was handling the media to get some pictures, black sticky carbon was coming off on my thumbs.
When I looked closer at the filter, I could see the fine carbon that the filter had collected. The arrows point at the thicker build-ups in the filter, but if you look close, you'll see that the whole element has this fine particle carbon build-up.
I scraped some with a knife and found the filter is actually pretty loaded.
I scraped the carbon of on to my finger and found that you could make a ball out of it.
This HPL oil is still cleaning, so I will continue to change the filter at 5,000 miles and report back.
