In Norway its 98 oct who is ethanol free, so that will approx. 102,3 Ron+Mon/2?
Maybe I need todo something with timing on ignition? Maybe it’s not wurth it... 98 oct is more expensive theb 95oct, and not all gas station have it.
However I see some report less fuel consumtion with 98 and more power?
1981 KZ650-D4, with 1981 z750L engine (Wiensco 810 big bore).

98 Ron = just under 94 oct using Ron+Mon/2 and since its ethanol free that would be my choice (mostly for that reason). ( As long as the price is not a big difference).
I have been mixing 93 and 89 for quite a while though as I feel for our compression it might run a tiny bit better.

Goggle octane rating conversion and if I read it right your 98 Ron rated gas is equal to our (US) Ron+Mon/2 ........93.5 to 94.
And your 95 oct is equal to our 91 which would be good. All depends on what you want to spend...... the ethanol free is good but at least 5% is better than 10% that were stuck with.
And I'd bet money the difference in power would be hard to feel. A few tenths of a HP ???
