Is there a mention of the S&S manual recommending 100 ron?
The S&S manual says to use, " a minimum octane rating of 91. Do not use fuel additives and avoid using methanol blended fuels. Ethanol blends of up to 20% may be used. Do not use E85 fuel in your S&S engine." It doesn't mention what sort of 91 (RON, MON or PON?) but I assume it is PON for the USA and that is about equivalent to 95RON for Europe.
