my friends have been trying to convence me to try using an octane booster on my car, telling me that it will vastly inprove the performance of my car, but i want to know if anyone has tried using it, and if so does it really improve the performance of our cars. the other question i have about the octane booster is if it could cause any damage to our cars?
