I was told by the dealer to user 89 (im from the states). Now i know the manual calls for 91-93Oct. They told me to use 89 due to carbon build up over time that for some reason these engines don't burn up the ethanol which causes carbon build up.

I use only 100% premium 91-93 gasoline.

95 unleaded petrol !

94

91 minimum. If there's 93 or 94 or anything above 91 where I need gas, I'll put the max.

The Owners Manual specifies fuel with a minimum octane rating of 90 (RON +MON)/2. In the US, the mid-grade fuel carries an octane rating of 89–90 so your dealer is correct. If you run a higher octane you'll make less power and get more carbon deposits secondary to partially unburned (slower burning) fuel.

I only use premium 98 and no ethanol fuels and 95 when I can't get 98. Same for my Fireblade. I ran the same in my 696 for 35,000km and no issues.

One size does not fit all apprently,

2015 821

2012 848

To answer your question I use premium (In Washington state that's 92 octane in my 848), I've read enough to come to the conclusion the opinions are vast and with out data I'm sticking to what the owners manual says...

Keep in mind that there are 4 different octane rating methods, ron, mon, aki and something else I can’t recall right now.
If the manual doesn't specifically list it as ron+mon/2 or aki then it is referring to ron rating. 95 Ron is 90 by the US standards.
So these two screenshots from the manual are exactly the same.

I always use premium.

I use 91 at Shell (here in Canada) as it is 0% ethanol. So, Shell's premium.

Like has been mentioned, nothing less than 90

Lower seems only better due to cost. I can't be bothered with shit fuel that pings (knocks)

"95" and "Premium" is an oxymoron.

Here in Europe, standard fuel is 95, premium goes from 98-100 Octane.

I use standard gasoline

 

[ChasT]

I use the standard EU95 in my 821.
In my D16RR I use the premium EU98, as the bike tends to sit about longer and I believe the 95 has ethanol, which isn't so good for the Desmo tank when it's not in use.

This is an equivalent of an oil thread ...

For me it's Shell 93. No real reason other than that's what I load my car up with.

Hmmm....I've been using 93 octane (10% ethanol) since I bought the bike. However since I've moved from MA to NY and found a few stations that carry 91 octane (100% pure), I'm thinking that's the better way to go. It may not make much or any difference, though. Thoughts?

Not having Ethanol in the fuel makes a big difference...not really that much in regards to power etc. but more so in being better for some of the parts of your engine...
