I made the switch to Mobil 1 a while back but did not have a place that could analyze oil samples, I have sense found a place locally. My first two tests involve Yamalube 10w40 and Mobil 1 10w30, I know the weights are a little different but I don't think that matters. I change my oil every one thousand miles. What I noticed was that the Yamalube dropped two grades from 10w40 to 10w20. The Mobil 1 stayed in grade that being 10w30. The wear metals that were tested for and showed up, Mobil 1 showed a drop in all of them.
Iron a 25% drop, from 12 ppm to 8ppm, Lead a 400% drop, from 4ppm to 0ppm, Copper a 30% decrease from 15ppm to 5 ppm, Chromium a 300% decrease from 3ppm to 0ppm, Aluminum a 300% drop from 3ppm to 0ppm, and Tin a 200% decrease from 2ppm to zero ppm.
I know that this is only one test for Mobil1 but I am less than 500 miles from my next oil change and will have that oil tested also. I do believe that these results will hold up at the next test.

Can you elaborate a little more on what those numbers mean? Those lower percentages of metals, are those presumably worn off from engine parts? What made you decide to try Mobil 1? I've heard that synthetics are much better in low temperatures, so this is good timing.
