Gas Additives

Short and sweet - do gas additives really do anything to improve engine performance, increase gas mileage, attract hot women , etc.?

I buy the stuff every now and then and drop it in before filling up. It's cheap enough that I figure, what the hell, can't hurt. But I always wonder if it helps...

You'll get more performance out of a big "NOS" sticker for the back window.

Most will help your gas mileage a bit. Plus they clean anything the gas goes through hence, the carb or fuel injectors.
