Can I use too much Sea Foam in my 2012 High mileage Honda Odyssey? Like every other tank? [SOLVED]

Thanks for the question, Debbie.

You can’t really use “too much” Sea Foam in the fuel tank of your 2012 high-mileage Honda Odyssey — Sea Foam is made from petroleum ingredients that are safe for your Odyssey and will not harm your engine when used as directed.

That said, for a vehicle that’s driven weekly, Sea Foam doesn’t need to be added to every single tank, unless you want to use it that way. For regular fuel system maintenance, we recommend adding the treatment to your fuel about every 3,000 miles. 

If your vehicle isn’t driven often or if fuel sits in the tank for longer periods, adding Sea Foam at every fill-up is also fine and will help keep fuel fresh and prevent gum and varnish from forming — there’s no downside to having Sea Foam in the tank more often.

Hope that helps and let me know if there’s anything else!

2015 Dodge charger v6 will it hurt it and how much is too much 110.00miles runs great

Hey Percy,

It won’t hurt anything. As far as how much to put in the gas tank for high cleaning concentration, I like to wait until the tank is low (1/4 -1/8 tank), add the whole 16 oz can, and then drive for at least 10-20 miles before refueling. It’s safe to add a high concentration like that and it works very well for cleaning fuel residues and deposits. One can in 2-3 gallons works great and is sufficient. The most you should add is a 1:2 ratio of Sea Foam to gas. But a can in 2-3 gallons is just fine. Hope that helps!
