In your case though, you have a slightly lower octane fuel grade, possibly because you are at a higher altitude? Here in the States, our "regular" grade gas goes from 87 octane to 86 and then to 85 as we go up in altitude. I've used all three, in the regions where they are the standard, with no problems whatsoever.
So, your fuel is also graded using only the RON value, and, your 90 and 94 octane ratings are pretty close to 86.5 and 90.5 here in the States. I'd just assume the 90 is really 87 and the 94 is really 91.
DO NOT ask for custom 90 and 94 tunes unless you are very careful to tell Bill that you burning RON rated fuel! I'd honestly just stick with fuel grade names of 87 and 91. DO tell Bill though what altitude you live at - it has an effect on the tune he writes.
Hope this isn't too confusing.

Ok, you know way too much... ... ... ... Lol, j/k. Anyway, how do I know for sure that I'm running just RON or MON? I made an attempt to look at different gas stations, and I actually did find a few that sold 87 octane gasoline. The specific one I go to, Mohawk, doesn't have 87, just 90 and 94. How do I know for sure what I'm going to be getting, when I'm filling up? Does the gas company just pick and choose what number they want to use or is it government mandated, etc?
Thanks bud!
