Thread: MECHANICS: Is sea-foam a good Fuel cleaner/ additive?

I have a 2006 Chrysler 300 3.5L V-6 55,000 miles. I use a bottle of sea foam about every 4 months to help clean the carbon and grime that this ethanol they put inour fuel will deposit. Is this a good/ great fuel aditive or am I buying something that is made for older engines, outboard engines, etc... I understand that Sea-Foam has been around since the 40's -- Seems like this stuff might be a little harsh.

Any suggestions of what kind of cleaner/ additive I should use, how often, and if it is necessary at all.

By the way I do see a slight increase in fuel mileage for the tank and 1 or 2 subsequent tanks... I just dont know if its cleaning or just octane boosting.

seafoam is the best thing you can get

although you dont need to use it that often.

and ethanol isnt that bad for you engine, your being way to dramatic..
