Archoil 2nd video. AR6400-D update and just added AR9100 to oil change.

Following up on my results with the AR6400-D and I just added the AR9100 during my oil change.
Just making these videos to share the results I’m getting so far.
I will continue to make some videos here and there to show results.
So far, I’m liking the product and it seems to be doing exactly what it advertises.
