How much Sea Foam in a Tecumseh 8hp snowblower engine? [SOLVED]

Thanks for the question, Bill.

If you’re asking about oil, add 1 ounce of Sea Foam per quart of oil.

Here’s what I’d recommend for adding it to fuel:

• If the engine isn’t running well, use a strong cleaning ratio (up to a 1:2 ratio of Sea Foam to gas). Run it until empty (using it as normal). That will do a good job cleaning up any gum or varnish in the fuel system that might be causing problems.
• If you’re using it for regular preventative maintenance, use 2 oz of Sea Foam per gallon in every tank. That will prevent gum and varnish from forming and the gas from degrading while it’s not being used.

Hope that helps and let me know if there’s anything else!
