I can't speak for ASP but my converted Saito 91 big did just fine at 22:1 fuel/oil. I took it apart when I put it back on glow, to clean and inspect, and found everything in the bottom end to be in absolutely mint condition. It had somewhere between 30 and 50 hours of run time on gasoline using Redline Two Racing Synthetic oil and Pennzoil Two Cycle Air Cooled. I think most will know the Pennz is mineral based and I couldn't tell the difference between the Redline and Pennz in performance. As I mentioned, it ran on both and looked perfect when I took it apart to inspect it before putting it back on glow.

It is now powering an AeroWorks Extra 260 doing 3D and I need every last bit of power at the absolutely lowest weight possible. That is the reason for the conversion back to glow.
