I've read the entire Moly & AW additive tutorials on the home page, and searched & read through much of BITOG forums & molakule's section, and *still* can't find a definitive answer. The one thing I found refers to how Moly plates up, then qualifies it by saying something about "...at least on ferrous metals...". Will it plate & protect well on the aluminum cyl wall of a new air-cooled Honda OHC lawn mower engine? Or will the zinc compounds have to do the lion's share of the work? Now, I know this is splitting hairs. With all those 20 to 30+ yr old Briggs engines still running out there, I'm sure any decent oil will be more than good enough. Still, I'm curious. All help appreciated.
