RELATED QUESTIONS
Can I use too much Sea Foam in my 2012 High mileage Honda Odyssey? Like every other tank?
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!
Can I add Sea Foam to my oil crankcase on my BMW 2013 316i N13?
Thanks for the question. Yes, you can absolutely use Sea Foam Motor Treatment in the oil crankcase of your BMW 2013 316i N13.
Here’s a little more info on how to use it:
- Add 1 ounce of Sea Foam per quart of oil in the crankcase. We recommend adding it 100-300 miles before your next oil change. That gives the Sea Foam enough time to circulate and clean, and it allows all the reliquefied oil residues to be drained away with the old oil. To help progressively clean up your oil crankcase, add it before every oil change.
You could also try High Mileage Motor Treatment. It’s made specifically for stubborn residues and deposits in higher-mileage vehicles. It’s a great cleaner!
How much and when should I add Sea Foam to my oil and my fuel for my Scion XB 2012?
Thanks for the question, Corrie. Here’s how much and when to add Sea Foam in your 2012 Scion XB:
- Sea Foam Motor Treatment in fuel. 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. Add it to fuel like this every 3,000 miles or once a year.
- Sea Foam Motor Treatment in oil. Add 1 ounce of Sea Foam per quart of oil in the crankcase. We recommend adding it 100-300 miles before your next oil change. That gives the Sea Foam enough time to circulate and clean, and it allows all the reliquefied oil residues to be drained away with the old oil. To help progressively clean up your oil crankcase, add it before every oil change.

Can I add Sea Foam to my oil if my 2010 Dodge Ram is burning motor oil?
Can I add 2 oz of Sea Foam per gallon to a full 10 gallon tank for the first time in a 2001 Mazda MX5?
Yes, you can add Sea Foam in that amount in a 2001 Mazda MX5.
That said, if this is the first time you’re adding it, I’d recommend adding it to a low tank to create an even stronger 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.
