91ron [usa 86-7pon/aki] at least equal to
98ron, first mistakenly used and compared
by this experienced road motorcyclist..
later used 95ron emergency fill one tank
[to avoid ethanol] deliberately feeling for
any differences, but nothing really..
back onto 91ron no ethanol and again
no real difference in performance in
various conditions including suburban
traffic, back streets and freeway..
addition of lv evoII slip-on exhaust
also no startling difference beyond
slight hp/torque increase and crisper
exit responses from corners[?]
higher anti-knock index fuels in this
10.7:1 compression ratio engine
are not necessary or better
in terms of combustion..
what you pay extra for is additives,
and the label 'premium'..
still, if you think it will be 'better'
then it will be, on some level..
