The testing stopped after 16 hours of heating time. I tilted the cups, sucked out excess oil, then used a little piece of paper towel in each cup to suck up a little more oil. The piece in the M1 0W-40 cup fell over, landing on some big agglomerations (“blobs”) and not letting go of them. Just imagine they are there when you see the picture of it. To see them all, requires moving one’s eyes or taking a video to get the lighting right, so my ranking of the results is based on better images than what I share here.
The M1 ESP 0W-30 and 5W-30 fans will be happy that they tied for the win in the test for resistance to forming deposits precursors (agglomerations/blobs) at 16 hours. These two oils had quite a few small blobs that don’t show up in the pictures, so they did worse than the pictures indicate. The gap between the best and worst is not large. QS 5W-40 got 3rd place and M1 FS 0W-40 got last place.
