98 RON or 91 RON

[Worm]

Whats ppls opinions on the grade of petrol to use.
IMO, using 98 RON is a waste. Does anyone have any proof or where they told from a mates brothers aunties sisters dad that 98 is the best and actually does something. I call BS.....

if you don't change the tune of your motor then you won't get any extra performance from 98, pretty much its less prone to detonation so you can run it harder with 98 before you come into trouble. I run 98 more of a security thing to help stop the motor pinging as if I don't pick it up the motor will be toast.

I have always run 98 octane on all my bikes and the pitty seems to run better with it it my opinion
