Sea Foam in lawnmower for winter storage [SOLVED] Asked by Laurie E. In Nebraska Can you put Sea Foam Motor Treatment in a lawnmower engine for winter storage?
Yes – Sea Foam Motor Treatment is very popular for winter storage.
Add at least 1 ounce of Sea Foam for each gallon of tank fuel. Run the engine long enough for the treatment to work through the entire fuel system. When possible, adding more Sea Foam when the tank is low will increase the cleaning and lubricating ratio when working the treatment into the engine.
