    What Octane? i can't get a straight answer!

    I did my search for the correct octane to utilize in my TTSE.  The manual says 87 Octane for the U.S. manual but everyone and their dog seem to have a different opinion.  This is a very European based Forum and your octane ratings seem strange to us in the States.  Our 87 octane is the lowest octane fuel we have over here.  It contains Ethanol which is basically a derivative additive made from corn. We have one in the middle 91 octane.   I had Harley's before and they always suggested going with our highest octane of 93.  I don't want to screw up my engine but am nervous about using such a low octane in my bike.  I have been burning 93 found without ethanol for a few hundred miles with good mileage results.  The 87 octane is a lot cheaper per gallon.  I know in Europe you go by the liter and really get ripped off compared to our prices in the States.  I don't know why the charge so much for fuel where you live.  Anyways, I just need direction.  If I need to burn 87 octane I will and not begrudgingly.  Thanks for your input and please don't beat me up over my inquiry!!

    I've never run anything but 87 with 10% ethanol in mine since the day I brought it home.  No issues.

    Thanks guys! Next fill up will be 87 octane.  I will really like the price difference.

    The USA is the odd country that measures octane using the (R+M)/2 method which ends up being about 3-4 numbers lower than the RON method used by the rest of the civilized world.  Regular in most of the USA (except high altitude states) is 87 whereas the same gas in Europe would be sold as 91 octane.

    It is a myth that higher octane is always better.  If your bike is made and tuned for Regular, run Regular.  Running Premium may actually be harmful (it has shown to be true particularly with the Rocket III engine).  Running Premium in the Trophy only dumps unburnt fuel out the exhaust.

    Thanks Tdragger!

    I know we seem to be uncivilized and don't believe we would fit well in the European community due to our volatile tendencies and in particular odd way of doing things.  But I appreciate the insight on utilizing regular 87 octane in the TTSE.

    Best Regards,

    I'm using mid-grade and the bike is running great. My dealer recommended 91 Octane but with a compression ration of 11:1  mid-grade is doing just fine.  No need to run the higher octane fuel.

    Tell the dealer to read the f'n manual which clearly states to run 87.  There's no excuse for a dealer to not know better.
