SUMMARY
Pour Sea Foam in your fuel tank to clean and lubricate your entire fuel system. It works through fuel injectors and carburetors to remove harmful residues and deposits from fuel passageways, intake valves, pistons, and chamber areas.
For cleaning a gasoline or diesel fuel system, it’s safe to add more Sea Foam to fuel. In fact, the more Sea Foam you add to fuel, the better it cleans!
Made from petroleum ingredients, Sea Foam is safe and effective when used in all types of gasoline or diesel fuels and fuel blends. Sea Foam does NOT contain harsh detergent or abrasive chemicals that can harm your engine or fuel system components.

Hi, if I want to use Sea Foam High Mileage to do a piston soak on my 2006 mx5 (suspected gummed up oil rings), how much do I add per cylinder? And for how long? I’ve read in one of the answers 1/4 ounce per cylinder, which is about 7.5ml in UK measurements. It seems very little. Thanks.
Great question Ash. What I typically recommend is 1/4(7.5 ml) to 1/2 ounce(15 ml) added to each cylinder through the spark plug hole. Rotate the engine back and forth a few times, don’t make a full rotation. Let the Sea Foam High Mileage sit in the cylinders for 12-24 hours and repeat the process one additional time. Before reinstalling or replacing the spark plugs, use the engine starter to turn the engine over for 10-15 seconds to clear any remaining Sea Foam out of the cylinders, then install the spark plugs. Once the engine has been restarted and allowed to reach operating temp, we advise to change the engine oil. Any Sea Foam and dissolved contaminates will seep past the piston rings and fall down into the engine oil. Note: the exhaust will smoke a lot upon initial start-up.
How much Sea Foam can I add to clean injectors in my car?
Good question!
The best way to use Sea Foam for cleaning (injectors, chamber areas, etc.) is to create a high concentration in a small amount of fuel. Add a full 16 oz can of Sea Foam Motor Treatment or High Mileage to 2-4 gallons of gas. Then, drive at least 20 miles before refueling. The high concentration will do a great job cleaning.
Hi my question is can I use Sea Foam on my 2016 WRX STI Subaru? There is a spray called the upper engine cleaner for Subarus and I can’t find it. That’s why I’m asking if I can use Sea Foam.
Thanks for the question, Enoc!
If you’re looking for an upper engine cleaner, use Sea Foam Spray. You can find it at most auto parts stores. It is applied through the intake and cleans intake valves and upper engine areas where a fuel cleaner can’t reach. It’s safe and effective in your Subaru.
Sea Foam Motor Treatment in the gas tank would also work in your Subaru, but it won’t clean buildup on intake valves in a GDI (because fuel does not flow over them).
Will using Sea Foam harm the catalytic converter on my gas engine? 2002 8.1 Chevy
Will Sea Foam help my car pass the smog test? It’s a 2014 Chevy Equinox 4 cylinder.
Thanks for the question, Suzy!
Here’s a page with everything you need to know about Sea Foam and emissions tests. https://seafoamworks.com/use-sea-foam-to-help-pass-emissions-tests/
The short answer is that Sea Foam Motor Treatment in the fuel tank and Sea Foam Spray through the intake will help your engine run cleaner and restore lost efficiency due to fuel residues and deposits. That doesn’t hurt in a smog test.
