Hi Little H
Please can you elaborate? I thought you put in octane booster to increase your RON rating to NEGATE detonation?
I ran my car with Octane booster for about 15 tanks in a row, and at first it was great and i little noticable better performance but after a while it was running rough, (idling poorly etc..) stopped using it and car went back to normal.
Also posted the question on SN and the general concensus was that if you car is not mapped to run at the higher octane ratings then dont run all the while.
I think its all down to you own experience, im not no technical wizard, and im sure someone can tell me different...[y]
