Although I am sold on Coleman for my G23 and plan on using it for other engines, I would be reluctant to recommend it for other peoples engines unless I tried it first in mine. The gas helicopter and gas boat people use Coleman in their Zenoah engines with no problems. I used it once in my Craftsman 22cc blower and it ran fine. I use it because it smells good and runs good for me, and it does not go stale. Maybe talk around to your resident expertrs or online and make your determination. I would follow the manufacturers recommendation during warranty at least and then experiment after if you want to. Another option for fuel is aviation gas which is higher octane, smells ok and does not go stale. Problem is a supply, unless you know a full scale pilot or a friendly airport FBO.

I like to experiment a little and have not had any problems doing so. But, I do read about my intents and then try to make a non-damaging decision.

Good luck, I think you will like gas. (have you considered a conversion for rc use of one of your lawn equip engines? Lots of info here on RCU in the engine conversions forum).
