Alcohol additive to gasoline

Yes Hammer it is. It helps remove moisture from your tank. It's primary purpose I believe is to remove harmful deposits in your cylinders especially carbon and in your carbs and or fuel injectors.
It comes very highly recommended by some of the mechanics around here and many guys on THT and other sites have been using it for years.
I don't know what else it does but those are the main reasons I use it. A good friend of mine who has been around boats and engines for 60 years says that he has heard nothing but good things and seen nothing but good results from it's extended use.
