I got some stuff called Fast Forward that cost a fortune and it seems to work ok, but adding a gallon of my racing gas is much better. The Fast Forward is supposed to work with either gas or alcohol and I carry a can of it for an emergency, but I have never found an over the shelf additive that really made a lot of difference. Only good thing about the Fast Forward is I don't have to measure the amount. But I still don't think it is anything to get excited about.
