I did the research....what is in Kymco book=92 but the number is what the Europeans use .....multiply by .95 and you come out with 87 something----so reg is fine. Then I looked under seat, decal, there it says 87 Octane for US use----I see no use to spend more money for what the machine doesn''t need.
Sometime long hard, uphill runs in the west---I buy a tank of super....but it really makes no difference. Long trips, every 1000 miles, I try to buy tank of Shell Super....for its cleaning capabilities.....probably all in my head.
