How much Sea Foam can I place directly into a chainsaw or a weedeater? [SOLVED]

Thanks for the question!

You can safely use Sea Foam in both a chainsaw and a weedeater. The amount you add depends on what you’re trying to achieve:

For regular use / preventative maintenance: Add 2 ounces of Sea Foam per gallon of fuel. This will prevent gum and varnish from forming as well as prevent the fuel from degrading.

For a strong cleaning (if it’s running rough or hasn’t been cleaned before): Create a high cleaning concentration with something like the following ratio:

• 8 oz of Sea Foam in 16–32 oz of fuel (up to a 1:2 ratio of Sea Foam to gas)

Run the engine for a few minutes to pull the treated fuel into the carburetor, then let it sit and soak overnight. After that, run it as normal. The high concentration works very well to clean varnish and residue from small engine fuel systems.

It’s safe to use a lot of Sea Foam in small equipment like that and it works well to clean.
