I was wondering which is better to run In these little 2-strokes, regular (87 octane), premium (91) or ethanol free gas? From my understanding on reading up on it a little, it’s better to put premium for how it burns in air cooled 2-strokes but I haven’t found any reliable info on it. I’ve used regular for about a year in my old engine and it has no real issues. But with my new one I’m shooting for longevity (2 years+) so I’m curious if it would make a real difference to fill up with regular as opposed to ethanol free or premium? I’ve ran all of them in my engine and noticed no difference between them, but I’ve heard it’s not something that you notice and it’s something that is better for your engine in the long run? Any info or thoughts? Thank you.
