The best way to clean the oil injection system in a two stroke engine [SOLVED]

I have a Johnson 150 horse two-stroke outboard with oil injection that uses a separate two-stroke oil tank. Can I add the Sea Foam marine product to my two-stroke oil to help clean the oil injection system?

Thanks for the question Kevin. Yes, it would help to add one ounce of Marine PRO per quart to your boat’s oil container. It will work to reliquefy any older/heavier 2-stroke oil residue that formed in the container, then continue to clean the oil passageways that go from the container to where the oil is injected into the crankcase.
