Thanks for the question, Laura. Yes, you can add multiple cans of Sea Foam. I’d wait until you have a low tank (2-4 gallons) and add a can or two of Sea Foam (or Sea Foam High Mileage, which is a great cleaner.) Then, drive it until almost empty before refueling.

Using a high concentration is a great way to clean up fuel injectors. It wouldn’t hurt anything to add three cans, but it’s probably not necessary.

Great question, Alberto. We get asked about this a lot!

No, it’s not bad to add a lot of High Mileage to your fuel. In fact, a high concentration works much better and faster than a low concentration. High Mileage is made with 100% safe petroleum cleaning and lubricating ingredients, so it’s okay to add a lot to fuel.

I like to wait until I have a low tank of fuel (1/8 of a tank or so) and add an entire 16 oz can of High Mileage to the fuel. Then, I drive it until almost empty before refueling. That works very well to clean fuel residues and deposits from the entire fuel system.

I’d wait until your tank is low and add the rest of the High Mileage, drive it until almost empty, and then refill from there and drive it normally.

Thanks for the question, Dimitris! Yes, you can use High Mileage in a wet clutch engine. It’s safe and effective.

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!
