    09' FX SHO Gas Question!

    i have stock 2009 Yamaha FX SHO and I always use Shell 87 octane gas! Is there better gas station or could I use 93 octane? I know the owner manual said use only 87..

    you can use 93 octane if you want, but 87 is sufficient for your ski (in stock form)

    Okay.. Will 93 octane run the ski smoother and better? Gain any more speed?

    No. Unless it is running bad stick with the 87. Then if its running bad there is most likely something wrong.
