That's interesting. I have a Honda tiller/cultivator and a Honda mower, and they both are specified to run on unleaded octane 86 or higher. The tiller is older and the manual doesn't even mention ethanol. I think I do them both a better favor by feeding them 87 octane ethanol-free gas, rather than E10 at a higher octane. (of course it's the opposite with the civic)On the other hand, my mower shop reccomends mid-grade in my Honda lawnmower.
What's also interesting, the tiller manual says if you hear some knocking/pinging at high load, don't worry about it. But if you hear persistent knocking at low speed, use a different fuel. If you keep using it with persistent pinging it will not be covered by warranty.
That's sort of similar to what Honda says about the civics Sport. If you use 87 and hear an occasional knock, it's fine.
Well, that may be true, but I prefer to never hear any knocks and then be afraid when trying to push it a bit.
