The best I have used a and still do today is simple mineral spirits AKA charcoal starter fluid . Use 1 pint to 10 gallons of fuel for cars and 6 oz for 6 gallons premix boat fuel .
To test if this is true take some seafoam and mix it with some water. If you see a phase separation then it's not alcohol but instead more oil based. It the seafoam and water will not mix if it's not alcohol based.

This is the first I've ever heard or read that SeaFoam is Alcohol and water? I figure it was more like xylene or toluene instead.

And it works. It will dissolve all the old burn carbon out of your engine and make it run better especially if it's an older engine. I use it in my truck, law mowers, chain saw, grass trimmber, gas blower, and boat all the time. Every one of my gas engines get seafoam and stabil in the gas they burn.
