Super 95 octan fuel is ok, no need to waste your money on Super Plus 98, V Power 100, Ultimate 102 octan fuel.

Ok stop... now you even have better fuel then we get in the states... 92 octane is the highest we get. Then you have Unocal 76 and Turbo Blue but they are both 110 octane, and $6 a gallon. Where 92 is $2.60 currently

In Maryland high test gasoline is 93 octane. All gas stations sell it. Ed

Europe uses the RON rating method which is higher than the (RON+MON)/2 method used in the USA.

Thank you all !

Scirocco, do you fill 98 before as last gas when the season ends, since the 98 don`t contain ethanol?

Super Plus 98 fuel contains 2 - 5 % Ethanol!!! If you need ethanol free fuel you have to fill up your gas tank with Ultimate 102 octan fuel.
I have read in other bike and car forums that Ultimate 102 octan fuel can be stored up tp 3 years without any gasoline stabilizers.

95 Ron = approx 91 oct Ron+Mon/2

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.

Just to all to the conversation this site lists fuel stations that sell non ethanol. Though many have not been updated in some time there are some with very recent comments. Keep in mind I in no way claim any of this is correct or current.

2 or 3 stations have worked out for me but they are 40 to 50 miles away. When I was working I'd be with in 12 miles so I stocked up then but gave it up after a couple years.
