I read all over the internet that Seafoam has alcohol and people don't trust it in their boat tank because that's what they are trying to protect it from. I don't know if I believe them because,
At the Seafoam website they say: Sea Foam has been tested and proven to work well in Ethanol blended fuels since they first appeared in the 1990s – even the newest E-85 blend. Ethanol has the effect of stripping the protective layer of motor oil from the cylinder walls, so the addition of Sea Foam Motor Treatment to your fuel actually helps to combat this drying effect by adding upper cylinder lubrication that helps to prolong the life of your engine and its fuel system components. Additionally, Ethanol can absorb moisture and when ethanol reaches its saturation point can cause what is known as (phase separation) this is when the moisture and ethanol can separate from the gasoline causing drivability problems and potential engine damage. Sea Foam helps control moisture in fuel caused by condensation by breaking moisture into molecules and dispersing it throughout the fuel, if moisture can not pool or collect ethanol can not absorb the moisture and renders the moisture harmless.
They also say: Regular use of Sea Foam in your fuel tank will help to ensure your injectors remain free of harmful deposits that can adversely affect your engine’s performance and fuel mileage.
Any thoughts or better product like Stabil marine?
