#1727 left Marc's shop with Amsoil 10w-40, everything good. For the next oil change I did a blend of Amsoil & Mobil 10w-30...noticeable occasional chain rattle, in addition to finding out additives are reduced now.

I like to do my research one time, find the best recommendation and move on. Been using Mobil1 in everything, but the ZR-1 getting full Amsoil from now on, period.
