Lohring,
Your post was misleading. You said modified Zenoah, without stating any details. Also lacking was the article you referred to., so you made it sound like Coleman fuel in general was AOK, which it is not.
Thanks for correcting that Coleman with octane boost is OK in some engines, mostly the ones that require regular 87PON only.
I tried Coleman with octane boost. It was a total bust. It detonates much worse than plain Coleman. I even tried running it in my lawn tractor. When I open the throttle it pings badly as the rpms increase. I have a gallon of junk.
