hey all friend of mine collected his evo 6 today,quick car dont like the power delivery compared to the impreza. while talking we got on to the topic of fuel he said he was given advice from a reliable source not to use octane booster and it is safe to use normal fuel, i know there different cars, but my question is if both where designed to run on 102 ron why is one safer than the other, or is it another evo driver myth
