Hello all, Any advice on the matter, "best" octane 85 thru 94? .... 2012 NC700X, only mods Delkelvic end pipe and K&N air filter. Thanks

Follow your owner’s manual’s recommendation, which is for Pump Octane Number (R+M/2) 86 or higher. This is for the rating system used in the United States. Other countries may use different octane rating systems, and the numbers will vary. Your pipe and air filter should make no difference. Air flow though the engine is likely to be primarily restricted by the cylinder head design.Hello all, Any advice on the matter, "best" octane 85 thru 94? .... 2012 NC700X, only mods Delkelvic end pipe and K&N air filter.

Thank you for the reply.My opinion...best octane is the one recommended by Honda for the machine, 87 grade with no more than 10% ethanol.
Out in the west up in the mountains I would use the 85 as it seems to be the equivalent of 87 back east.
I did use a tank of E15 this summer while travelling in the US. I hadn't seen that before (I live in Canada) and put it in by mistake. I didn't realize that the second nozzle on the pump was only for E15. Anyhow, the engine survived without any apparent issues.Never use E15 (sometimes labelled "88 octane"), the fuel system is not designed for it. Consequences are... unknown, but why risk it?
That’s the first time I’ve heard that one. Can you explain why? Funny how all those people I noticed using 85 in their FI cars in Colorado were unaware.85 octane was made for carburetors to compensate for higher elevation effects. Not reccomended for modern FI systems.
Yes, but run a search on "the history of 85 octane fuel".That’s the first time I’ve heard that one. Can you explain why? Funny how all those people I noticed using 85 in their FI cars in Colorado were unaware.
I understood that 85 wasn’t made to compensate for anything. It simply is a high enough octane rating for operating typical automotive engines in thinner air, and can be offered at a lower cost. Modern FI engines are, in general, better equipped to compensate for variables in temperature, barometric pressure, etc, than those with carburetors. Knocking is not just about the fuel-air mixture, but also about the engine’s compression ratio, heat management, cylinder head design, etc.
I was asking in post #11 if you could explain why 85 octane gasoline was made for carburetors but not recommended for modern FI systems, as you had stated. I wasn’t looking to be redirected and assigned the task of researching the topic.Yes, but run a search on "the history of 85 octane fuel".
Careful with the "everyone does it, it must be right" mind hack. Do you really think that they buy 85 octane for any other reason than it is the cheapest, regardless of if it voids their warranty?
Yet that is where you find yourself. I'm not going to try to convince you w/ back & forth when you can read and arrive at an informed decision of your own.I was asking in post #11 if you could explain why 85 octane gasoline was made for carburetors but not recommended for modern FI systems, as you had stated.

I've seen this routine before. Someone makes a statement, but can't back it up with facts or an explanation, rather they take the deflection route or easy route and say to just go read about it. Well, I have, and I disagree with your statement about 85 octane. Conversation over.Yet that is where you find yourself.

Well, that would be your routine. Typical. Suspect you did look it up and found the gov't report ref origin of the use of 85; didn't support your opinion. Can't support your opinion, so Twitter logic of everyone does it so it must be right. As expected. Conversation over.I've seen this routine before.
