Re: Carbonated fuel??

[David Stanton]

I do have a couple of non-gasoline uses for Seafoam.

I dump half a can of Seafoam slowly down the carb at a fast idle on my Mercruiser I/O for winter storage. An old friend that has had several inboard cruisers recommended that years ago to coat upper cylinder and valves. My I/O is Mercury’s build of a 4.3 Chevy V6. Then I make sure the tank is near full of ethanol-free.

Last fall, I bought a can of Seafoam spray and shot it in the sparkplug holes of a 1953 Buick straight 8 engine I had just purchased that I will be installing in my 51 Buick soon. Then I turned the engine over by hand a couple of times. It was a very aggressive spray pattern, so I’m sure it protected the cylinders well.
