In my manual it says for Canada and Europe minimum octane rating is 87 (R+M)/2 Method? But just before it says bike needs minimum 91 octane rating. Also If that is the case it also says my bike takes up to 10% ethanol so do I use just regular 87 octane at chevron? And I don't need the 91 nor 94 octane rating I've been putting into my bike?
If it says it accepts 10% ethanol do I have to up my octane rating? or Keep it at what it says (For Canada 87 octane) becuase it has a diff section for ethanol and doesn't say if It can do 87 octane and 10% ethanol?
