I have been looking at octane boosters for various reasons(better perfomance blitz ecu mapped at 101 ron etc).

I know that 1 octane pt

= 0.1 and all that, but what conserns me is that most over the counter octane boosters are for lower grade fuel.

From what I understand US fuel is 88-91 octane and this is were octane booster really works.

The higher the octane the fuel if you just add any old chemical to boost octane then in theory the balance could be wrong and a waste of money?

I use 99 ron whenever possible and 97 when I have no choice but here is the question.

Is it worth using octane booster on 99 ron fuel and if so which one?
