This report is from my first run of Amsoil 20w-40 V-twin synthetic in my Victory Cross Country Tour. The two previous samples on the report are Victory-brand semi-syn oil. As you'll note, the wear metals have decreased slightly, but I can't say for sure it is resulting from the Amsoil--it could be an extension of the downward trend in wear metals as the engine "matures". In my opinion, the Victory oil seems to be as good (within the margin of error) as the Amsoil in this particular application. I'll continue to run the Amsoil, as I can get it cheaper than the Victory stuff. NOTE: oil filter used was a NAPA Gold, and during the two runs of Victory oil it was the Victory OEM filter.
