would octane booster make a noticeable differance to my 94 wrx? I always run it on optimax which i know is 98 ron and with the octane it would be 100 ron but would it make that much differance if i put some in?

i think you should do ron, ron, ron,

the do ron, ron.

how much is it?/where can i buy it from?......

Depending on what octane booster you want, NF, Millers etc, you can get Millers from Scoobymania quite cheap.
