Amsoil Saber is good oil, don't get me wrong but the 80:1 ratio is a highly debated topic. If Amsoil says to run it at 100:1 and you are running it at 80:1 then in theory you are running to much oil in your gas which can cause (depending on the machine) excess oil in your engine. Now, I have never had an engine releated issue caused by that oil but I'm am trying to follow the actual manufacturer's recommendations. I am not an engineer so I am not going to assume I know whats better for my engine. The engineers that manufacture these machines know what it takes to make them run good. As I get older and less rogue (HAHA) I trying to follow more rules than I used too.
