Yea, It surprised me too when Randy mentioned it. I'm wasn't trying to bash any oil, but I'm sure if you ask he will confirm what I'm saying.
I can tell you I ran nothing but Redline racing @ 50:1 for quite a few years. It protected well obviously, as everything on the low ends was well lubricated (Had a nice shene of oil), and all showed little wear, but my oldest and most used saws (372/346) had a thick "Hard crusted" carbon deposits that he had a tough time removing while he was doing the port work.
I've used Amsoil also more recently @ 50:1 but the saws I sent that had only seen Amsoil were fine w/no deposits. Also have not likely used Amsoil long enough to form these deposits anyways.
I do typically cut at high altitude 6000-8000 ft and believe that could something to do with it.
Wouldn't have otherwise known as I never had a problem. Also these saws were not running overly rich.
I'm going to try his recommendation as there are few with anywhere near his experience.
Bottom line is "If you like and trust it, then stick with it".
What gasoline were you running?
