I've been using the STP cleaners every now and then, but yeah the straight additives have been proven to even reduce power.

I also hear those octane boosters can fuck up your plugs.

Sometimes its not that the additive is bad but more of its not enough to change in a positive way on what the car is tuned on from the factory/modded.
