it will adjust itself, but reseting the ECU will speed up the ECU in learning the fuel in the car :)

Be careful with the definition of 'octane'

Do not compare US and UK figures, they are not the same.
One is (RON+MON)/2, the other just RON

I'm not sure what they use in India, not that it matters lol.
I remember getting fuel from some blokes with a barrel and a handpump, who knows what crap they had mixed in there and what had already evaporated - the bike pinged a bit but survived though.
