How to use Sea Foam for engine storage and stabilizing fuel

Good question, Ray. If the generator isn’t running well because of gum/varnish (one of the most common causes of small engine problems), Sea Foam needs to make it through the fuel system (come into contact and clean whatever’s causing the problem). It’ll clean as it runs, so if you’re able to run it for a few minutes, add a relatively large amount of Sea Foam (at least 8 oz per gallon of fuel) before you start it. From there, it’ll clean while it runs as long as there’s Sea Foam in the fuel. Might take a tank of gas to clean things up.

That said, I’d get a can of Sea Foam High Mileage or Sea Foam Motor treatment and follow the instructions below, especially if the fuel is old or the generator has been sitting for a long time:

1. Remove the old fuel from the tank, then drain the fuel from the carburetor (usually a screw).
2. Add a cleaning dosage of Sea Foam to an empty tank followed by a small amount of fresh fuel. Add one part Sea Foam to 3 or 4 parts fresh gasoline (1/3rd can and a pint of gas would work great).
3. With Sea Foam mixed in the tank fuel, rope pull/crank or press your primer bulb 3 or 4 times to draw the fresh fuel and Sea Foam into the carburetor.
4. Then let the engine sit overnight  to allow the Sea Foam to dissolve any fuel residues from the carburetor (older or excessive gum/varnish may need to soak two to three days).
5. Once the engine starts, the Sea Foam in the fuel will continue to clean and help restore lost engine performance.

That summarizes how to overcome a gummed-up carburetor. Your pressure washer’s carburetor is vented to the atmosphere, so while it goes unused, the lighter layers of fuel in the carburetor circuits evaporates and the heavier layers form sticky gum and varnish that will restrict fuel passageways. Sea Foam works to quickly reliquefy the heavy gum/varnish back into the fuel so everything clears up inside the carburetor! Going forward, always run Sea Foam in your small engine fuel systems to stabilize the fuel (prevent gum and varnish formation). Hope this helps!

Yes, you can use Sea Foam Motor Treatment in your diesel stand by generator. It’s safe and effective in any gas or diesel engine. Add one ounce of Sea Foam per gallon of fuel for routine/every tank maintenance. Once in a while for a stronger cleaning dose, add a high amount of Sea Foam (a full 16 oz can of Sea Foam to 2-3 gallons of fuel) and run until almost empty before refueling.

Yes, Sea Foam Motor Treatment works great for treating fuel for storage. Add 1 ounce of Sea Foam per gallon of fuel in the tank.

As far as “too much,” you really can’t go wrong. Sea Foam Motor Treatment is made with 100% safe petroleum ingredients. The more you add to fuel, the better it cleans (as long as you don’t exceed a 50/50 ratio of Sea Foam to fuel (which is very excessive!)). For storage, 1 ounce per gallon will be fine, and a little extra won’t hurt anything.

If you want to clean out your fuel system, add a high concentration (8 ounces per gallon) to a gallon or two of fuel, and ride until almost empty before refueling. That will do a great job cleaning.

Lastly, here’s a quick video on storing a motorcycle with Sea Foam: https://www.youtube.com/watch?v=U00vq6_6iTw

Yes, you can add Sea Foam. Sea Foam Motor Treatment is safe to mix with other additives.

Thanks for the question, Kenneth. No, Sea Foam Motor Treatment will not restore the fuel. Once gasoline is degraded, a fuel additive isn’t able to bring it back.

Here are a few ideas:

• Sea Foam is great for generators, especially if they’ve been run with old fuel. Add 2 ounces of Sea Foam per gallon of fuel. Once in a while, add 8 oz of Sea Foam to half a gallon of fuel and run it through to give it a good cleaning. The Sea Foam will clean out residues and buildup in the fuel system and carb passageways.
• Sea Foam is great to add to fresh gasoline that will be stored for a while. Add at least 1 ounce per gallon of fuel.
• You can gradually use up the old fuel in a car or truck if you mix it with fresh gasoline.

Hope that helps!
