If you put in anything lower than 93 the bike will catch fire when you hit 80mph. Happened to me today, bike is in the shop.

But in all seriousness I am glad you guys all know that you should run 87 since the engine is made for it. Too many people think because 93 is "premium" that it is somehow better and therefore worth the extra money.

Whats everyones opinion on ethanol? I know most regular gas contains 10% ethanol.

ethanol sucks!! worse fuel economy, degrades fuel lines faster, cost more.. what is the point I dont get it.. There are a couple gas stations in my state that I stop by on road trips, they do not have ethanol gas. Whatever I am driving has noticeable more power, smoother idle and just an overall better feeling

I was putting 89 because I couldn't find what gas to put. But now that I found it, where it says nothing less than 87, meaning 87 is ok and everyone here who probably know more than me agree. Well next time ill pump 87. Which is lovely from going 91 gas to 87. SAVE ME SOME MONEY NINJA lol. Plus I almost always get that light that means your driving is being economical.

Ethanol sucks... uhhgg... unless you have one of those fancy flex fuel engines hahaha!!!

gunks up carburetors... promotes moisture buildup making them add more **** in the gas to prevent just that... clogs injectors... degrades your fuel system... clogs fuel filters.. omg the list goes on...

In the motorcycle manual, it says the Ninja 300 is capable of handling the 10% ethanol just fine. It also goes on to talk about other fuels, but that one stuck with me.

the dealer recomends 91 to help keep the bike in top running order. you can run with 87 but at only a few pennys less I will treat mine to the 91 only. you get over 60mpg so I dont see why you should use less. just for fyi there is a big difference in 87 and 91 but it is your bike.
have fun all

91 is not "better" for the engine in any way.

The higher octane rating prevents detonation under higher compression ratios. The engine was designed to run on 87 octane so there should be no benefits from running 91.

Most gasolines now contain 10% ethanol, look at the pump and you will probably see a sticker. Yes, it does lower your fuel economy.

What he said ^, lol

For shits and giggles, I ran a tank of 87 and a tank of 91 back to back. On both tanks I flogged the motor quite well, and noticed no difference between the two. There was no pre-mature detonation on the 87 at all, just as with the 91 (obviously). Low compression = low octane OK!

Its a good idea because of that ethanol crap to add a cap of fuel stabilizer to each tank to keep it clean.

Its basically equivilant to a cheaper option than using those lucas or seafoam or whatever.

Use em in small proportions every tank is much better than once in a while to clean it out.

Some gas stations do not put ethanol in their premium fuel. I have not found one near me but in Ohio there were plenty.

That is the only reason I would run premium in this bike.

US and AUS use different octane measurements. Our "premium" is 92 or 93 and most engines that require premium say 91+ (like my CBR...)

They are referring to PON I believe and you guys use a diff measurement.
