Has anybody else used LiquiMoly 2 stroke oil? I bought a 6 pack of liter bottles off Amazon for $28 shipped. It seems to run great in my saws (441, McCulloch 650, 251) and is pretty cheap. I've run a few gallons of mix through my 441 and it seems to burn clean and doesn't stink like Stihl ultra did to me. I found it merely by scanning through the JASO tested list and saw it was both cheap and FD rated....
