gen 1 best fuel

[Falcon 269]

Higher octane means more bang per amount of fuel used, hence better throttle response and fuel economy.

Actually, it means greater resistance to premature detonation ('knock').  It burns slower and allows the use of a higher compression ratio in tuned motors.

It's not necessary to use higher octane fuel in our Fazers.  In theory, there should be no discernible benefit, either.  However, as I predicted, several here report personal experience that suggests otherwise. 

A classic case of try it for yourself and make up your own mind, I think.
