Re: 100:1 Mix
Ferball,Your thoughts are pretty similar to mine about what happens on a molecular level and I'm no more qualified than you to have an opinion... just trying to picture it in my mind.
As for the case of engine failure, if I remember right that was flybytaco and the oil was Amsoil Sabre, not Opti-2. I've had good luck with both, but now use just Opti-2 since last summer with good results. However it works, it does work, so I guess it doesn't matter if I understand it well or not. I appreciate the lack of stink running the chainsaw with it.
Someday when I grow up I will probably lose interest in toys with wheels, but until then...
