You are right on the octane but most of these engines were not designed to run on ethanolNot true at all. If the manufacturer of the engine recommends regular, then that is what you should run. If said engine requires 87-89 octane, you are sacrificing hp by running a higher octane fuel. I run regular fuel in my chainsaw, power auger, generator and quad. No issues at all
