Good question. Yes, soaking engine components or fuel system components (carb parts), transmission parts, and/or hydraulic system parts in a Sea Foam bath is a great way to clean parts.

Start with a slow cooker (crock pot). Either buy a new one for the kitchen (don’t use it for food again after using Sea Foam in it!), or purchase a cheap one dedicated to parts cleaning. Add enough Sea Foam Motor Treatment, High Mileage or Marine PRO to sufficiently cover the parts that need to be cleaned. Add the parts, put the cover on and turn the slow cooker on low or medium for 12-24 hours. After the “cooking time,” remove the parts and gently brush off the loosened contamination with a soft bristle brush or bottle brush to clean the remaining debris off the components. Pipe cleaners work great for small passageways. If there is still more contamination that needs to be cleaned, repeat the 12-24 hour “cooking time” and re-assess the parts. Hope that helps!

Thanks for the question!

Add one ounce of Sea Foam per quart of oil in the crankcase.

Also, check out the article on our site about oil burning and its common causes. That will help explain what Sea Foam can and can’t do for a vehicle that’s using oil.

If the oil use is caused by varnish or buildup, Sea Foam can help. Sea Foam reliquefies oil residues and deposits so they can be drained away with the old oil. I’d recommend the High Mileage version. It’s a great cleaner.

We recommend adding it 100-300 miles before your next oil change. That gives the Sea Foam enough time to circulate and clean. It also lets you drain away all the reliquefied crud (residues and deposits) when you change your oil.

Good question, Mary. Yes, Sea Foam Motor Treatment will help clean fuel injectors. I’d recommend the High Mileage version (in a silver and black can).

Here’s what I’d do: wait until the tank is low (1/4 -1/8 tank), and add the whole 16 oz can. 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.

Good question, William. As far as safety goes, you can add Sea Foam to your gas tank as often as you’d like. Adding a can to your gas tank every 3,000 miles (or 2-4 times a year) is enough to keep your fuel system clean and running strong. I’d also consider using High Mileage – it’s a strong cleaner and works great on vehicles with higher mileage.

Another tip: wait until the tank is low (1/4 -1/8 tank), and add the whole 16 oz can. Then, drive until almost empty before refueling. A high concentration like that works very well for cleaning fuel residues and deposits.

You can add Sea Foam to the oil before every oil change. However, do not exceed one treatment per oil interval, and never add more than 1 ounce of Sea Foam per quart of oil. Adding Sea Foam before every oil change will work great to progressively clean away oil residues and deposits.
