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.

How often should I use Sea Foam in a 4 stroke motorbike?
Good question, Dan.
Here’s what I’d do: once a year, wait until you have a low tank of fuel and add a high concentration of Sea Foam Motor Treatment (up to a 2:1 ratio of gas to Sea Foam. 32 oz of fuel and 16 oz of Sea Foam). Then, ride it until about empty before refueling. The high concentration will do a great job cleaning any fuel residue or deposits.
If it’s sitting for a while between uses, you could add 1 oz of Sea Foam per gallon of fuel to every tank. That will prevent gum and varnish from forming while it sits, as well as preserve ignition vapors and prevent the fuel from degrading.
How much Sea Foam do I add for an 11.9 gallon fuel tank?
Thanks for the question! It depends on what you’re trying to accomplish by adding Sea Foam.
For cleaning, 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. Do that every 3,000-5,000 miles and you’ll keep your fuel system and critical engine areas clean. (For boats/tractors/anything else, do it at least once per season).
That’s the best way to get the most out of a can of Sea Foam.
If you’re storing a vehicle/fuel/fuel tank, add 1 ounce of Sea Foam per gallon
Can I run my lawn mower with only Sea Foam for a good, deep clean?
Good question, Steve. A lawn mower won’t run on straight Sea Foam, but you can use a high concentration of Sea Foam in gas for a good deep clean.
I’d do something like this: run your mower until empty, and add 8 oz of fuel with 4 oz of Sea Foam (a 2:1 ratio of gas to Sea Foam). Then, run it until empty.
If I already use Stabil in my generator fuel….what does adding Sea Foam buy me?
Westinghouse WGen9500DFc generator.
Thanks for the question, Kevin. In addition to stabilizing fuel, Sea Foam cleans gum and varnish from the entire fuel system and prevents it from forming. Gum and varnish is often the cause of rough performance or hard starts. Sea Foam will clean it out, helping your generator start and run better.
