Some years ago someone, can`t remember who, did a comparison between 95 and 97 fuel in the uk.
If i remember right the 97 gave an extra 10% mileage. In theory its richer so you use less, is this correct?
On the other hand, in Malaysia they have genuine 100 ron courtesy of Petron Blaze. A test was carried out using motorbikes on a run from Ipoh to Penang and back. The result was very good with improved fuel economy and better combustion leading to a smother ride and better throttle response.
Is there a mention of the S&S manual recommending 100 ron?
