Sea Foam as ethanol stabilizer [SOLVED]

Thanks for the question, John. A quick side note about ethanol treatments: something represented as “ethanol treatment” might cause a false sense of security. Be aware that adding a fuel treatment isn’t going to change ethanol from what it is. Just know that when combined with water, ethyl alcohol has corrosive potential in a fuel system.

Anyway, to answer your question, Sea Foam’s petroleum ingredients will add protective lubricity to fuel system parts. Another key is avoid letting fuel sit for long periods of time (if you can, use and replenish it frequently…), or favor the idea of buying small amounts of fuel more frequently so you’re going through it at a faster rate. No matter what gas you’re running in your Mercury, remember that Sea Foam is always working to clean and lubricate your fuel system.
