I have a Banshee & my son has a Blaster. Neither of them require fuel with an octane rating of 91 (pump gas). Are there any downsides to running high octane (100+) ethanol-free unleaded in a motor that doesn't require it? The cost is obvious, I'm referring to performance or reliability. Honestly, I'd happily pay a few extra bucks just for the smell of Klotz. Haha! Let me know what you think. Thanks.
