yes, if you want or have to use the wrong octane fuel in your car, then booster will help. of course you don't know what else the booster might do or how long it will last. it may create major carbon deposits or last for only a few days (which has been known to happen). i'd rather just use the right stuff in my car and not worry about it.
my point was that if you have the proper fuel in your car and the engine is tuned correctly, then booster won't help.
