Little confused with your AKI, MON and RON talk.
Searched and read alot of threads....So heres the story
I hope to run 150psi and i have a 4*Keyway
and you guys are talking about 87 and 91 octane...
the lowest here to buy is RON95 unleaded,
and in my car i put the Super RON98 and did the same on my 2005GPR
I have found a link what should clear up a lot i hope....
Hope you can explane the differance on your 91 and our 98
i think 98 is overdone for my ski....
i sure hope....freaking expensive 95 is cheaper.
I pay $2.44 dollar a liter....(1 L ≈ 0.2641720523 US liquid gallon)

AKI = anti knock index (r+m/2)
95ron is somewhat equivalent to 90 r+m/2
98ron is somewhat equivalent to 93 r+m/2

So my RON98 would be USA AKI 93-94...?
What would be to much or not

I would run 98 with that setup. I run 98 with just the timing, better to be safe than sorry.

Here you go.
100 octane UK-= 95 octane US
98 octane UK-= 93 octane US
95 octane UK-= 91 octane US.
I know there's lots of talk about running the higher octane the better, but you need only to run the right octane for your setup. i.E-if your ski needs 93 octane US and it runs good on that, running 95 octane US might actually slow you down, because the higher the octane, the slower the fuel burns.
